In pea plants, tall plants are dominant over short, and green pods are dominant over yellow. If you were to cross two plants that are both heterozygous for both traits, what portion of their offspring would you expect to be short and yellow-podded?

Final answer:

When crossing two heterozygous plants for both tall and green pod traits, 25% of the offspring would be expected to be short and yellow-podded.

Step-by-step explanation:

When two plants that are heterozygous for both tall and green pod traits are crossed, the offspring can inherit different combinations of alleles. For the short trait, the recessive allele is needed, so the offspring would need to inherit two recessive alleles from both parents. Therefore, the portion of offspring that would be short would be 25 percent.
