Question

If one individual is Tt and another individual is tt, which of the following is true?

Answer 1

This sounds like a multiple choice question.

It would probably help if you listed all of the choices.

Let's assume that capital T means Tall,
and lowercase t means short.

Here's a Punnett Square, to show how one parent with (T t)
and another parent with (t t) would cross:



You see on this Punnett Square...
Two boxes have the genotype (T t)
and the other two boxes have the genotype (t t).

There are four boxes in all.

What this means is that if one parent with (T t)
mates with another parent, with (t t),

Then there's a 50% chance that the offspring will be tall (T t)
because 2 out of the 4 boxes are (T t).

And there's a 50% chance that the offspring will be short (t t),
because 2 out of the 4 boxes are (t t).
