适应度和选择系数
|
加入三个基因型的存活子代数目是：
基因型: A1A1 A1A2 A2A2
后代数： 10 5 2
则适应度fitness
w11=10/10=1;
w12=5/10=0.5;
w22=2/10=0.2
Fitnessis defined as the relative reproductive success of a genotype.
选择系数s
selection coefficient s=1-w
s11=0; s12=0.5; s22=0.8
selection coefficient (s) is the relative intensity of selection against a genotype.
We usually speak of selection for a particular genotype, but keep in mind that, when selection is for onegenotype, selection is automatically against at least one othergenotype.
