Heritability

Question 1

heritability

Answer 1

how much phenotypic variation is due to genetic variation in a population

Question 2

broad sense heritability

Answer 2

H^2

ratio of total genetic variance to total phenotypic variance

Vg/Vp

Question 3

narrow sense heritability

Answer 3

h^2

ratio of additive genetic variance to the total phenotypic variance

Va/Vp

Question 4

total number of phenotypes =

Answer 4

alleles + 1

Question 5

total number of genes

Answer 5

(total # phenotypes -1) / 2

Question 6

Phenotypic variation =

Answer 6

genetic variation + environmental variation

Vp = Vg + Ve

Question 7

Genotypic variation =

Answer 7

additive variation + dominant effects + interactions

Vg = Vd + Va + Vi
