Question

An inflated green pod is dominant over constricted yellow pod. When a pure pea plant is crossed with an inflated green pod and a pure pea plant is crossed with a constricted pod, what proportion of the phenotypes in the offsprings could be expected to have inflated green pods and constricted yellow pods?

Answer 1

Answer:

Explanation:

I'm assuming this is a simple case as used in high school textbooks with each trait only needing 2 copies of the same gene to express. In that case parent plant #1 with the inflated pod will have gametes that all contain one copy of only the gene for inflated pods. Parent plant #2 will have gametes that all contain one copy of only the gene for constricted pods. Which means, since every pea seed that is successfully fertilized is the result of 1 gamete from each parent meeting, that each seed will be heterozygous for both traits. Which trait expresses will depend on which is dominant.
