Question

Bees pollinate red snapdragons in one part of the garden then fly over to another area and pollinate white snapdragons. After a few generations, the seeds from the white snapdragons start to produce pink snapdragons. Identify the mechanism that brought this change in gene frequencies. Select one of the options below as your answer:
A. Genetic drift
B. Gene flow
C. Reproductive isolation
D. Disruptive selection

Answer 1

disruptive selection is also called as incomplete dominance.
RR gives red colour
rr gives white colour
Rr gives intermediate colour ie in this case pink...

Answer 2

Disruptive selection, also called diversifying selection, describes changes in population genetics in which extreme values for a trait are favored over intermediate values. In this case, the variance of the trait increases and the population is divided into two distinct groups.[1][2] This evolutionary process is believed to be one of the main driving forces behind sympatric speciation.
this is the exact definition.

Answer 3

I know white and red make pink and its incomplete dominance i couldn't remember what the other word incomplete dominance was. But thank you so much!
