Question

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

What pattern of inheritance does flower color in these flowers follow?

A.) multiple alleles

B.) incomplete dominance

C.) polygenic traits

D.) codominance

Answer 1

Hello!!!!

when experiment on peas were repeated using other traits in other plants it was found that sometime the F1 had a phenotype that did not resemble either of the two parents and was in between the two the inheritance of flower colour in the dog flower ( snap dragon or Antirhhinum species) is a good example to under stand incomplete dominance

it is result of incomplete dominance, hence option B) is correct...

hope this help you!
