What is the probability of producing a child that will phenotypically resemble either one (one OR the other) of the two parents in the following crosses?
a) Aa bb cc dd X AA BB CC DD
b) Aa Bb Cc Dd X Aa Bb Cc Dd
c) Aa bb cc dd X aa bb cc dd
Make sure to show your work in details.
What is a reciprocal cross?
Cross 1: Purple Stem (P1) x Brown Stem (P2) = F1 Generation (all purple stem plants).
Cross 2: F1 x F1 = F2 Generation (295 purple stem plants and 102 brown stem plants).
a) What is the phenotype ratio of the F2 generation?
b) What is the geneotype ratio of the F2 generation?
c) Which trait is dominant?

A) What cross could you perform to help your friend determine the genotype of his petunia plant? B) How will this cross help you determine the genotype of your friend's red- flowered petunia?
