Most American robins lay an average of 3 - 4 eggs at a time. Laying more eggs often leads to malnourishment of the young. Laying fewer eggs typically leads to a decrease in viable offspring. Which evolutionary process does this best describe?

Question

(1 point)

Odirectional selection

Odisruptive selection

Ostabilizing selection

Increased selection

Answer 1

This best describes stabilizing selection, as it is favoring the average number of eggs laid (3-4) rather than extreme values, which could lead to negative outcomes for the offspring.
