Question

Two pink-flowering plants are crossed. The offspring flower as follows: 25% red, 25% white, and 50% pink. What pattern of inheritance does flower color in these flowers follow?

Answer 1

Co-dominance

Step-by-step explanation:

Considering the allele for red pigment as CR and that for a white pigment CW, a pink flower will equally express both the pigments in its phenotype and will thus have a genotype of CR CW.

Crossing CR CW × CR CW you'll get,

25% CR CR - red flowers

50% CR CW - pink flowers

25% CW CW - white flowers
