Question

Which processes lead to most genetic variation in sexually reproducing organisms? select all that apply. select all that apply. crossing over cytokinesis independent assortment of chromosomes in meiosis random fertilization?

Answer 1

The answers are crossing over, independent assortment of chromosomes in meiosis and random fertilisation. Crossing over, especially, causes genetic recombination and results to traits that are different from either parents.
Another process that leads to genetic variations is genetic mutations.

Answer 2

The processes that lead to most genetic variation in sexually reproducing organisms are the following;

-          Crossing over – the process of exchanging genetic material that occurs during sexual reproduction

-          Independent assortment of chromosomes in meiosis – the process where maternal chromosomes are not separated in a cell with the parental chromosomes separated

-          Random fertilization – responsible for the sperm and the egg to meet
