# [[亲 ]]
'''育种'''('''Breeding''')即生育后代。在[[十字军之王 III]]中,这个概念也包括了旨在增加某些[[先天特质]]遗传可能性的策略。过程通常涉及到与拥有期望特质的[[角色]]结婚,故意剥夺那些没有遗传到期望特质的[[继承人]]的继承权。
 
== 特质遗传 ==
先天(也称为遗传)特质可以遗传给角色的后代。虽然先天特质必须是可见([[#激活和未激活特质|激活]])的才能提供能力增益和其他效果,但是角色也可能拥有不可见([[#激活和未激活特质|未激活]])的特质,这些不可见的特质也可以被子女遗传。<ref>"[Genetic traits are] visible, though characters can also carry recessive traits... those are not visible, but can be inherited by their offspring!" [https://forum.paradoxplaza.com/forum/threads/ck3-dev-diary-07-characters-portraits.1295264/page-3#post-26089470 rageair's reply] in CK3 Dev Diary #7 - Characters & Portraits thread</ref>
 
有些特质可以被子女遗传,但不适用激活/未激活遗传机制。本条目中的“先天特质”不包含这些特质,也不包含那些[[后裔特质|不是先天但也可遗传的特质]]。
 
=== 激活和未激活特质 ===
一个先天特质可能是激活或者未激活的,激活特质可见并且提供效果,而未激活的特质被隐藏。先天版本的{{iconify|Melancholic|抑郁}}、{{iconify|Lunatic|精神错乱}}和 {{iconify|Possessed|附身}}特质[[#先天特征列表|总是未激活地遗传]],而在之后的人生中变为激活状态:<ref>{{cite file|game\events\trait_specific_events\trait_specific_events.txt}},<code>trait_specific.0500</code></ref>

==== 激活遗传的概率 ====
遗传到一个激活的先天特质的概率取决于父母拥有的特质的状态(激活或者未激活):<ref name=Defines>{{cite file|common\defines\00_defines.txt}},<code>NChildbirth</code></ref>

=== General logic for trait with tiers inheritance ===
# Start from highest trait
# Calculate active chance. Lower tiers ( including inactive ) count as inactive of the tier. Each level down beyond the first multiplies chance by a define
# If active, use it; DONE
# Otherwise, go down a tier, if inactive pretend 1 more parent has that tier active, otherwise 1 more parent has it inactive.GOTO 2
 
When trying to inherit a tiered genetic trait, and the other person has one of lower tier, we pretend that means they've  got the higher tier one recessively, and reduce the chance of inheritance by 20% per tier further down than 1 the other parent's trait is.
 
When going down a tier, add 40%.<ref name=Defines />
 
=== 先天特征列表 ===
下表包含了所有使用上述遗传机制的先天特征。<ref name=Traits>{{cite file|common\traits\00_traits.txt}}</ref><ref>"[If genetic = yes, the trait's] inheritance will follow the following rules: The trait can be inactive. Children can inherit the trait from both active and inactive parent traits. [...] An active trait is inherited with 100% chance, an inactive trait with a 50% chance. If the trait is successfully inherited from both parents, it becomes active. [...] If it's inherited only from one parent, it's inactive." Developer comments in {{cite file|common\traits\_traits.info}}</ref> 某些特质不列入此表,例如 {{iconify|Sayyid|赛义德}},它可以从角色的非亲生父母处遗传(秘密私生子的情况), 或者 {{iconify|Inbred|近亲繁殖}},它使用单独定义的遗传概率。''天然概率'' 一列表示角色不是从父母处遗传,而是出生自带该特质的概率(某种意义上,类似于突变)。如果特质拥有天然概率,其随机概率(也就是生成的角色拥有的概率)也可以假 是相同的值。<ref name=Traits /> 注意,某些特质不能同时遗传,因为他们是不相容的;如果特质属于同一组,将会表明。

== 近亲繁殖 ==
近亲繁殖是两个有亲缘关系的角色生育后代的过程。有亲缘关系的角色拥有至少一位[[#共同祖先|共同祖先]]。Such children can be born with [[#Traits gained from inbreeding|negative congenital traits]] even if neither parent has them, or the {{icon|Inbred}} [[#Inbred|Inbred]] trait in advanced cases. However, there is a [[#Pure-blooded|small chance]] for the child to gain the {{iconify|Pure-blooded}} trait instead.
 
In the first generation, small-scale [[incest]] such as cousin marriage may not have a massive immediate impact. Nonetheless, repeated instances over successive generations may have an accumulative effect through negative inherited traits and a [[#Common ancestors|narrowed gene pool]].
 
=== Chance of inbreeding ===
[[File:Chance of inbreeding.png|500px|thumb|right|A line graph showing chance of inbreeding based on common ancestors.]]
The chance of a child being considered inbred can be found from the product of the following:<ref>"The final chance [for inbreeding] in percent is given by the number of common ancestors X corresponding level factor X inbreeding chance modifier" Developer comments in {{cite file|game\common\defines\00_defines.txt}}.</ref>
* Number of [[#Common ancestors|common ancestors]]
* [[#Inbreeding factor|Inbreeding factor]] based on number of common ancestors
* Inbreeding chance modifier. Currently, only the {{iconify|Pure-blooded}} trait [[#Effect of Pure-blooded on inbreeding|provides such an effect]].
 
==== 共同祖先 ====
The more common ancestors two parents have within four generations (up to their great-great grandparents, and including themselves), the more likely their children will be inbred.<ref>{{cite file|game\common\defines\00_defines.txt}}, <code>NChildbirth|INBREEDING_ANCESTOR_GENERATIONS = 4</code></ref> Some potential incestuous marriages are noted below. The value provided for common ancestors assumes that ancestors were otherwise non-incestuous and monogamous. Cousins are not removed. Additionally, the value is relative to the breeding couple.
{| class="wikitable sortable"
|-
! Relation
! data-sort-type=number | Common ancestors
! Explanation
|-
| Full siblings
| 30 (maximum possible)
| By definition, (full) siblings share parents, and thus by extension all other ancestors. The maximum amount of ancestors from ''n'' generations can be found from <math>\text{Max Ancestors} = 2 ^ {n + 1} - 2 </math>, thus being 30 from 4 generations. Or, written out, full siblings share both parents (2), two sets of grandparents (4), four sets of great grandparents (8) and eight sets of great-great grandparents (16).
|-
| Parent-child
| 15
| In the case of a partner being the other partner's ancestor, they are counted as a common ancestor.<ref>The fact that the parents themselves are included in the common ancestor count is implied in the wording of developer comments found at {{cite file|game\common\defines\00_defines.txt}} (emphasis added): "How many generations are checked for common ancestors of the both parents '''(including the parents)''' for the purposes of getting the inbreeding trait and the pure-blooded trait"</ref> As a result, the common ancestors are the following (perspective is child/parent): parent/self (1), one set of grandparents/both parents (2), two sets of great-grandparents/standard grandparents (4), four sets of great-great grandparents/great grandparents (8). Note that the parent's great-great grandparents are the child's 3×-great grandparents, and are therefore not counted.
|-
| Half siblings
| 15
| They share one parent, and therefore share only half of the maximum amount of ancestors. Alternatively, they share one parent (1), one set of grandparents (2), two sets of great grandparents (4) and four sets of great-great grandparents (8).
|-
| First cousins
| 14
| First cousins share grandparents (2), two sets of great grandparents (4) and four sets of great-great grandparents (8).
|-
| Uncle-niece/aunt-nephew
| 14
| Similar to first cousins, but rather than sharing grandparents, the nibling's grandparents are the uncle/aunt's parents. Note that since the uncle/aunt's great-great grandparents are the nibling's 3×-great grandparents, who are 5 generations away from the nibling's perspective, they are not counted.
|-
| Second cousins
| 6
| Second cousins share one set of great grandparents (2) and two sets of great-great grandparents (4).
|-
| Third cousins
| 2
| Third cousins share one set of great-great grandparents.
|}
 
==== Inbreeding factor ====
The inbreeding factor for a given amount of common ancestors can be found through the following:<ref name=Defines />
{| class="wikitable"
! Common ancestors
! Factor
! Chance before modifiers
|-
| 0-14
| 0.33
| Between 0% and 4.62%
|-
| 15-16
| 0.75
| Between 11.25% and 12%
|-
| 17-19
| 1
| Between 17% and 19%
|-
| 20-21
| 2
| Between 40% and 42%
|-
| 22-30
| 3
| Between 66% and 90%
|}
 
==== Effect of Pure-blooded on inbreeding ====
The Pure-blooded trait provides {{green|−50%}} chance of inbreeding per parent. If two parents have the Pure-blooded trait, this effect combines to no chance of gaining traits due to inbreeding. Note that this excepts the chance of gaining the Pure-blooded trait [[#Chance of gaining the Pure-blooded trait|naturally]], as well as the inheritance of such traits [[#List of congenital traits|via parents]]. It is unknown whether the Pure-blooded trait has an effect on gaining the Inbred trait.<ref name=TalkPagePureBloodedEffect/>
 
=== 通过近亲繁殖获得的特质 ===
The following traits may be gained from inbreeding. Note that these ''general inbred traits'' may also be [[#List of congenital traits|gained naturally]] and are congenital. Offspring only have a chance to gain these traits as a result of inbreeding if their parents do not possess any of these traits (plus the {{iconify|Inbred}} trait).<ref name=TraitsInfoFile>"[enables_inbred = yes] enables the children of the character to be considered for the inbred trait (no by default). It only enables the inbred chance if there are common ancestors of the parents, so there is no risk of 'inbred' if the parents are not related. If inbred is not enabled by parents' traits, but there are common ancestors, there's a chance (same as for inbred trait when it's enabled) the child will get a random trait with enables_inbred = yes." Developer comments in {{cite file|game\common\traits\_traits.info}}</ref> The traits below appear equally likely.<ref name=TalkPagePureBloodedEffect />
 
* {{iconify|Barren}} / Sterile
* {{iconify|Scaly}}
* {{iconify|Club-footed}}
* {{iconify|Wheezing}}
* {{iconify|Spindly}}
* {{iconify|Giant}}
* {{iconify|Hunchbacked}}
* {{iconify|Bleeder}}
* {{iconify|Dwarf}}
 
Additionally, there are two traits that may only be gained initially through inbreeding and have special requirements: {{icon|Inbred}} [[#Inbred|Inbred]] and {{icon|Pure-blooded}} [[#Pure-blooded|Pure-blooded]].
 
==== Inbred ====
The {{iconify|Inbred}} trait may be inherited from one's parents. It may also be gained if a character with a ''[[#Traits gained from inbreeding|general inbred trait]]'' has children with someone with whom they share a common ancestor.<ref name=TraitsInfoFile /> The chance of gaining the Inbred trait as a result of this is unknown. Note that even with highly incestuous marriages, no children will gain the Inbred trait if the parents do not possess any of the enabling traits.<ref name=TalkPagePureBloodedEffect />
 
==== Pure-blooded ====
The Pure-blooded trait may be [[#List of other inherited traits|inherited from one's parents]]. Otherwise, it may be gained naturally. Similar to the chance of inbreeding, the chance of gaining the {{iconify|Pure-blooded}} trait naturally is based on the number of common ancestors, multiplied by the corresponding level factor for that amount of common ancestors:<ref name=Defines />
{| class="wikitable"
! Common ancestors
! Factor
! Final chance
|-
| 0-19
| 0
| 0%
|-
| 20-21
| 0.15
| Between 3% and 3.15%
|-
| 22-30
| 0.3
| Between 6.6% and 9%
|}
As a result, parents must have at least 20 common ancestors for a child to gain the {{iconify|Pure-blooded}} trait naturally. This does ''not'' apply to inheriting it from parents.
