Answer 15

For number 2 what do you think it is?

Answer 16

2. D
3. B

Answer 17

Number two is Stabilizing selection is the opposite of disruptive selection. Instead of favoring individuals with extreme phenotypes, it favors the intermediate variants. It reduces phenotypic variation and maintains the status quo.

Answer 18

Number three is Disruptive selection, also called diversifying selection, describes changes in population genetics in which extreme values for a trait are favored over intermediate values.
