Answer:
Parent cross= ttrr (short, wrinkled) × TtRr (hybrid)
POSSIBLE GAMETES BY EACH PARENT:
ttrr - tr, tr, tr, and tr
TtRr - TR, Tr, tR, and tr
Explanation:
This question involves two genes in a certain plant. One gene is coding for height while the other is coding for seed shape. The alleles for tallness (T) and round seeds (R) is dominant over the alleles for shortness (t) and wrinkled seeds (r).
According to this question, a parent that is short and wrinkled (ttrr) is crossed with another parent that is hybrid (TtRr) for both traits. This means that the parent cross is as follows: ttrr × TtRr
The possible combination of gametes that will be produced by each parent is as follows:
ttrr - tr, tr, tr, and tr
TtRr - TR, Tr, tR, and tr
See attached image for the punnet square using these gametes.
