Question

Puppies born too large experience difficulties in birthing and tend to have respiratory and other problems. puppies born too small often can’t compete with their siblings for their mother’s milk. thus, puppies born not too large or too small have a survival advantage. this is an example of ___ selection.

Answer 1

The answer would be natural selection

Answer 2

Stabilizing selection

Step-by-step explanation:

This type selects individuals with intermediate phenotype, that is, closer to the average. The extremes, in this case, have a disadvantage over the others, not being selected.

This selection can be seen in the question above, which shows that puppies too small or too large have serious survival disadvantages, while puppies with the intermediate phenotype, which are medium-sized puppies, have survival advantages when compared to the other two phenotypes.
