How Does Meiosis Promote Genetic Variation? Independent Assortment - Each chromosome is randomly sorted independently of other chromosomes during metaphase I & II (chromosomes are like cards being shuffled then dealt)

How Does Meiosis Promote Genetic Variation? Crossing Over - During prophase 1, chromosomes come together in homologous pairs forming tetrads. Sometimes, these pairs will swap the same segment of genes (crossing over).

How Does Meiosis Promote Genetic Variation? Random Fertilization – the fertilization of an egg and sperm is completely random

Asexual Reproduction (Mitosis) A method of reproduction where a single parent gives rise to two genetically identical offspring, without the use of gametes.

Sexual Reproduction (Meiosis) Reproduction that involves the exchange of genetic material between two organisms.
