Problem: Suppose that phenotypic variation in the tail length of mice is summarized in the table below.What is the narrow-sense heritability (h2) of tail length? What is the broad-sense heritability (H2) of tail length?
FREE Expert Solution
Broad Sense Heritability: estimates percentage of genetic variance using all components of genetic variance
: ratio of genotypic variance to phenotypic variance
Narrow Sense Heritability: estimates percentage of genetic variance using only additive variance
: ratio of additive genotypic variance to phenotypic variance
Variance Components of a Quantitative Trait:
VP = VG + VE + VGE
where: VP = phenotypic variance
VG = genetic variation
VE = environmental variation
VGE = variation associated with the genetic and environmental factor interactions
