Question

Robins typically lay four eggs. Four eggs allow the offspring to be well fed, whereas larger clutches may result in malnourished chicks that have a lower chance of survival. Fewer than four eggs per clutch may result in no surviving offspring if the eggs are preyed upon. Which pattern of natural selection most likely acts to keep four eggs the most common clutch size>

Answer 1

Answer:

Stabilizing selection

Explanation:

Stabilizing selection is one of the types of natural selection. In this process, some members of the particular specie do not survive. The one who survives helps to reproduce.

As per the given question, the pattern of natural selection that is acted to keep the common clutch size is four. In case more eggs are laid, some would be preyed on. The remaining eggs are exposed to better nourishment and a good survival rate.
