释义

Genotype frequency

中文百科

基因型频率

在群体遗传学中基因型频率指在一个种群中某种基因型的所占的百分比。

它可以这样表示:

f(\mathbf{AA})

比较等位基因频率。

哈蒂-温伯格定律预测在特定条件下得知等位基因频率时可以这样计算基因型频率:(p为A的等位基因频率,q为a的等位基因频率)

f(\mathbf{AA}) = p^2
f(\mathbf{Aa}) = 2pq
f(\mathbf{aa}) = q^2

基因型频率可以用de Finetti 图表来表示。

Genotype frequency 基因型频率

A de Finetti diagram. The curved line is the expected Hardy–Weinberg frequency as a function of p.

Genetic variation in populations can be analyzed and quantified by the frequency of alleles. Two fundamental calculations are central to population genetics: allele frequencies and genotype frequencies. Genotype frequency in a population is the number of individuals with a given genotype divided by the total number of individuals in the population. In population genetics, the genotype frequency is the frequency or proportion (i.e., 0 < f < 1) of genotypes in a population.
