Question

Variation in offspring is important in maintaining genetic diversity within a population. Which of the answer choices indicates a mechanism of introducing genetic variation in a population? Select all that apply.

A) crossing over during meiosis
B) fertilization of an egg by a sperm
C) independent assortment during meiosis
D) mitosis producing two new daughter cells
E) binary fission resulting in two bacterial daughter cells

Answer 1

The answer would be A, B, and C.

Step-by-step explanation:

Since genes shuffle and assort randomly in meiosis, this is a cellular process that results in greater genetic diversity. Because haploid gametes form a diploid zygote in fertilization, this also increases genetic variation. However, binary fission and mitosis only result in daughter cells that are clones of the parent cell.
