Question

The phenotypic variance for scutellar bristles in an isogenic line (i.e. all
individuals are genetically identical) of Drosophila is 1.7. An outbred line
from the same source population from which the isogenic line was
derived has a phenotypic variance of 2.5. Assume no genotype by
environment interactions.
a. What is the genetic variance in the isogenic line?
b. What is the environmental variance in the isogenic line?
c. What is the heritability in the isogenic line?
d. What is the genetic variance in the outbred line?
e. What is the environmental variance in the outbred line?
f. What is the heritability in the outbred line?​
