1. possible gamete genotypes produced by an individual of genotype ppdd are
a) pp and dd
b) all ppdd
c) pd and pd
d) pd, pd, pd, and pd

D) PD, Pd, pD, and pd

Explanation:

You need to draw a Punnet chart and put P (represent a dominant character) and p (represent a recesive character) abobe. Then D (represent a dominant character diferent than P) and d (represent a recesive character different tan d).

When you do the cross over, you will end with four possibles gamete genotypes and those are PD, Pd, pD and pd.

after making a punnet square using bv bv bv bv you will find that the ratio will be 9: 7 or a 128.6% probability.

hope this
