Variance and Evolution

Question 1

what is used to measure discrete variation?

Answer 1

gene and genotype frequencies
Hardy-Weinberg castle which looks at gene and genotype frequencies as well as mating frequencies and derivation
binomial expansion

Question 2

what are the assumptions underlying HWC?

Answer 2

infinite pop size - no genetic drift
no selection
random mating
no mutation or migration etc

Question 3

what is used to measure continuous variation?

Answer 3

mulitple alleles and multiple genes
P = G + E and the basis for quantitative genetics
additive genetic variance and heritability
- mean p^2a - q^2a
- variance 2pqa^2
- heritability h^2 = Va/Vp
