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
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.
if we`ll not classify living beings then it`ll become difficult to study all of beings one by one. In order to make their study easier biologists have classified all living beings into five major groups.
