please help, phenotypic proportion

Post by clarissatania » Tue May 22, 2012 6:40 am

If the a and b loci are 40 cM apart and an AA BB
individual and an aa bb individual mate:
a. What gametes will the F 1 individuals produce,
and in what proportions? What phenotypic classes
in what proportions are expected in the F 2 gen-eration (assuming complete dominance for both
b. If the original cross was AA bb 3 aa BB, what
gametic proportions would emerge from the F 1 ?
What would be the result in the F 2 generation?

So how could we find the phenotypic proportions?Is it like A_B_, A_bb, aaB_, and aabb?

Cis or trans? That's what matters.
