If u have 2 plants one homozygous dominant for yellow seeds and 1 recessive for green how many will be yellow?

Question

Out of 100 offspring, how many could be yellow seeds.

Answer 1

Let:

Y=yellow

y=green

The cross would look like this:

YY x yy= all Yy (all yellow seeds)

All 100 ffspring would have yellow seeds.

Answer 2

I would think 75% yellow and 25% green.

But my final answer is No Solution.
