Heritability Flashcards
1
Q
heritability
A
how much phenotypic variation is due to genetic variation in a population
2
Q
broad sense heritability
A
H^2
ratio of total genetic variance to total phenotypic variance
Vg/Vp
3
Q
narrow sense heritability
A
h^2
ratio of additive genetic variance to the total phenotypic variance
Va/Vp
4
Q
total number of phenotypes =
A
alleles + 1
5
Q
total number of genes
A
(total # phenotypes -1) / 2
6
Q
Phenotypic variation =
A
genetic variation + environmental variation
Vp = Vg + Ve
7
Q
Genotypic variation =
A
additive variation + dominant effects + interactions
Vg = Vd + Va + Vi
