The concept of natural selection is a mechanism of evolution where environmental pressures select for phenotypes that exist in populations based on genetic variation. Which process below would not contribute to the genetic variation in a population of mice?
A) mitotic growth
B) sexual reproduction
C) mutations resulting from errors in DNA synthesis
D) crossing over of homologous chromosomes during meiosis

Mitosis produces two identical daughter cells, which should have no new diversity as a result. Meiosis (including crossing over), sexual reproduction (including fertilization), and mutations (from changes to the DNA) all contribute to genetic diversity and new phenotypes.

The concept of natural selection is based on genetic variation so mitotic growth would not contribute to the genetic variation in a population of mice. Hence option 4 is the correct option.

What is mitotic growth?

At the time of mitosis, a cell duplicates all of its contents, including its chromosomes, and splits to form two identical daughter cells without variation.

The concept of natural selection is a mechanism of evolution where environmental pressures select for phenotypes that exist in populations based on genetic variation is a property of meiosis or physical reproduction.It allows genetic variation by a process of gene shuffling which happens when the cells are dividing. Where the sperm and egg cells unite, and contribute 23 chromosomes each to result an embryo.

Hence, as mitotic growth does not show genetic variation, option 4 is the correct option.
