Mendel crossed true-breeding plants having yellow peas with true-breeding plants having green peas. The resulting plants all had yellow peas. An F1 cross resulted in 3/4 of the plants having yellow peas and 1/4 of the plants having green peas. What does this tell you about the alleles for color?

Ainsley Boyle · Answer 1

The alleles for the yellow peas were dominant.

Explanation:

If 3/4 of the pea plants came out yellow and 1/4 of the pea plants came out green then the yellow pea plants are more common making them dominant.
