Question

1. In a cross between two parents (the P generation) where one is a homozygous short pea plant (tt) and the other is a homozygous tall pea plant (TT) you find that all of the offspring are tall (all the F1 are tall). What allele is dominant? How do you know? Use a Punnett square to answer. 2. If you mated two of these offspring pea plants together to make an F2 generation, what types of offspring would you see? and in what proportion? Use a Punnett square to answer.

is a homozygous short pea plant (tt) and the other is a

Step 1

In this case, since all the offspring are tall when one parent is homozygous dominant (TT) and the other parent is homozygous recessive (tt), we can conclude that the dominant allele is T. Show more…
