Population and population genetics 群体与群体遗传学 Population: entire group of organisms of one kind an interbreeding group of plants and animals; the extensive group from which a sample might be taken.群体是由交配和亲子关系相连的个体构成 的集团 Mendelian population: A natural interbreeding unit of sexually reproducing plants or animals sharing a common gene pool孟德尔群体是指能相互交配 以有性方式产生个体的集团

The Hardy-Weinberg equilibrium in animal populations 动物群体的平衡 ➢ Allele frequencies and The Hardy-Weinberg equilibrium 基因频率与Hardy-Weinberg 平衡 ➢ Calculation of allele frequencies in randombreeding populations 随机交配群体基因频 率的计算 ➢ The Hardy-Weinberg equilibrium for over one locus 一个以上座位的平衡
Allele frequencies and The hardy Weinberg equilibrium 基因频率与 Hardy-Weinberg平衡 Y Allele frequency: The proportion of one allele relative to all alleles at a locus in a population 个群体内某一定等位基因的频率叫做基因频 率,其中A1的频率为 X1=(2Nn+Nn)(2N)=X+x12/2 A2的频率 X2=1-X1=X12/2+X22
Allele frequencies and The HardyWeinberg equilibrium 基因频率与Hardy-Weinberg平衡 ✓ Allele frequency: The proportion of one allele relative to all alleles at a locus in a population 一个群体内某一定等位基因的频率叫做基因频 率，其中A1的频率为： x1 = (2N11+N12)/(2N) = X11+X12/2 A2的频率 x 2 = 1-x1 =X12/2 + X22
