Homework Statement
A geneticist studying the number of bristles on the second leg of fruit flies determined that a wild-type strain has a mean number of 486.3 bristles per leg. A sample of males and females from this population with 420.0 bristles were bred and the offspring had a mean bristle number of 432.0
a) what is the heritability of bristle number?
b) if you were to select a group of flies with 500.0 bristles and breed them, what would be the mean bristle number in the progeny?
c) If we wished to generate a population of flies that had a mean leg bristle number of 450.0, what parents should we select?
Homework Equations
Vp = Va + Vd + Vi + Ve + V(g)(e)
Vg = Va + Vd + Vi
H^2 = Vg / Vp
h^2 = Va / Vp
The Attempt at a Solution
I honestly don't even know where to begin. I have tried contemplating for 20 minutes on what to freaken do and I'm getting very frustrated. If someone could PLEASE at least point me in the right direction (I get it if you don't want to solve it) then I would really appreciate the help. My teacher is no good.
Thank you very much
