If you have P generation where one parent is homozygous dominant
for both traits and the other parent is homozygous recessive for
both traits, what will the F1 genotypes be?
If you then cross F1 x F1, what will the F2 genotypes be?
Assuming that the trait is one of “complete dominance”, what will
be the F2 frequency of offspring with 1) both dominant traits, 2)
one trait dominant and one trait recessive, 3) one trait recessive
and one trait...
