Question

1. How many different phenotypes are possible in the offspring of two parents with genotypes AA and aa, where A is the dominant allele for a trait and a is the recessive allele for the same trait? (1 point)
one
two
three
four

I believe it's one, but wanted to make sure.
Thanks :)

Answer 1

Four I believe.

Answer 2

I thought
Genotype is the group of letters.
Phenotype is the look.
and since A is the dominant allele they all the offspring would be tall?
So there would be only one phenotype?

Answer 3

one is right don't listen to them
