The short stem trait (t) is recessive to the tall stem trait (T). If a homozygous short pea plant is crossed with a heterozygous tall plant, what is the chance that the offspring will be short?

Question

A. one out of four
B. three out of four
C. all four
D. two out of four

???

Answer 1

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

Answer 2

I think I get what your saying so B right?

Answer 3

nope: how many short (tt) are in the offspring....

Answer 4

I don't want you to think I'm guessing because I'm trying. So 4 right?

Answer 5

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.

Answer 6

Can you help here?

Answer 7

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?

Answer 8

I am not much help in biology, but it looks as though you've got it, Amber.

Answer 9

Thanks Mrs. Sue I just got confused. :)

Answer 10

I thought it was Two At and Two tt
Well thanks anyway
