Question

Two pink-flowering plants are crossed. The offspring percentages are 25% red, 25% white and 50% pink.

If a red-flowering plant was crossed with a white-flowering plant what would the phenotypes of the offspring be?
A. all red
B. all white
C. all pink
D. half red, half white

Answer 1

C. Assuming the gametes for red flowering plant is heterozygous and the white is homozygous, it will be all pink

Answer 2

Answer:

D. half red, half white

Explanation:

We just have to follow the simple parallel ratio from Parent to F1 progeny. The half red and half white flowering plants will be produced because in F2 progeny there will no phenomenon of co-dominance as was in F1. This will produce a very simple allele transfer by showing both of phenotypes in the same proportion at the same time.
