第十章 族群遺傳 (Population Genetics)

第十章 族群遺傳 (Population Genetics). 大綱 幾個重要的定義 族群內個體的多型性 Hardy-Weinberg 的理論 何計算對偶基因頻率與基因型頻率 影響族群內對偶基因頻率與基因型頻率的因子 近親繁殖 . 族群 (Population) 某特定地區內,一群可以互相交配的生物個體。 族群是由同種的生物組成,如一座山內所有的白頭翁總和,就 組成一個白頭翁的族群 基因池 (gene pool) 一個族群內所有的生物個體對偶基因的總和。 人類基因池 : 是指一個族群內所有人類基因的總和

Evolution

Evolution

Evolution. Change in a population over time. Evolution is a Theory. You do not have to believe in the theories of evolution presented in these chapters. Many different theories will be presented. You are responsible to know about all the theories.

Hardy- Weinberg Equilibrium

Hardy- Weinberg Equilibrium

Hardy- Weinberg Equilibrium. Hardy- Weinberg. Establishes a benchmark from a non-evolving population in which to measure an evolving population. Investigates the properties of populations that are not evolving. Hardy- Weinberg Theorum. States that:

A Hardy Weinberg

A Hardy Weinberg

A Hardy Weinberg. Problems. Calculating new Allelic frequencies. All of the alleles at a locus must equal 100%. If there are two alleles let p=the dominant and q=the recessive So p+q must equal ??? 100% or “1”. Practice. If p = 0.6 what is q? P + q = 1 0.6 + q = 1 q= 0.4.

Selection and Genetic Variation

Selection and Genetic Variation

Selection and Genetic Variation. 1) selection against recessive alleles If alleles are recessive lethal, then selection can only act on them when they are homozygous consider Dawson’s flour beetles: started with population of all heterozygotes, + / l

Dominance

Dominance

Dominance. Refers to an allele’s phenotypic effect in the heterozygous condition NOT its numerical prevalence For example, a Dominant allele may be LESS common than a recessive allele!. Dominance. If the dominant and recessive alleles A and a (with freq. of p and q) are in H-W Equilibrium
