D. two out of four

tt(homozygous) x Tt(heterozygous)
offspring: tT,tt,tT,tt
T is a dominant gene
tT is tall
tt is short

I think I get what your saying so B right?
Answered by bobpursley
nope: how many short (tt) are in the offspring....
Answered by Amber
I don't want you to think I'm guessing because I'm trying. So 4 right?
Answered by bobpursley
of this offspring
Tt
tT
tt
tt

How many short (tt) are there. I dont count four at all. You have four pairs of genes ( , ) from which to look for t,t. Tt do not make a short plant, only tt.

Can you help here?
Answered by Amber
Oh!!! That's how I messed up I thought since Tt had a short t in it that it counted, but it doesn't so it would be 2 right because tt and tt?
