Question

Define the term broad-sense heritability. What is implied by a relatively high value of H2? Express aspects of broad-sense heritability in equation form.

Answer 1

Broad-sense heritability is a measure of the fraction of phenotype variation in a population that can be attributed to genetic differences among individuals. A high value of H2 indicates a strong genetic influence on the trait. It can be expressed as H2 = VG / VP in equation form.

Step-by-step explanation:

Broad-sense heritability is a measure of the fraction of phenotype variation in a population that can be attributed to genetic differences among individuals. It reflects the extent to which genetic factors influence a trait. A relatively high value of H2 implies that a large proportion of the phenotypic variation is due to genetic factors. In equation form, broad-sense heritability can be expressed as:

H2 = VG / VP

Where H2 is broad-sense heritability, VG is the genetic variance, and VP is the phenotypic variance.
