3.circular DNA tightly wrapped around histones
4.long, linear DNA with no histones

Answer;

d. when the majority of a population is decimated and there are only a few remaining organisms left to rebuild the population

Explanation;

-Genetic drift can have major effects when a population is sharply reduced in size by a natural disaster (bottleneck effect) or when a small group splits off from the main population to found a colony (founder effect).

-Population bottlenecks occur when a population's size is reduced for at least one generation. Because genetic drift acts more quickly to reduce genetic variation in small populations, undergoing a bottleneck can reduce a population's genetic variation by a lot, even if the bottleneck doesn't last for very many generations.
