Genetics Principles – Lesson 5: Meiosis
5.1 Meiosis Defined
Meiosis produces gametes (egg and sperm cells).
During meiosis, hereditary info is exchanged amongst the maternally and paternally inherited copies of a couple of chromosomes so that you can produce brand new combinations of genes. This technique of hereditary recombination helps you to increase variability that is genetic a species. It permits for the transmission of practically unlimited combinations of genes from moms and dad to offspring.
The ensuing gametes have actually 23 brand brand new chromosomes, one person in each one of the 23 pairs, representing unique combinations for the maternal that is original paternal copies.
5.2 Meiosis Terminology—Homolog
Homologous chromosomes , or homologs, comprise of this known people in any provided chromosome set. One person in the homolog could be the chromosome through the mom and also the other member is through the dad.
During meiosis, homologs pair together. (more…)
