What Student Need to Know about The Key Differences between Mitosis, Meiosis, and Inheritance.

Genetics owes a great debt to good drawing. Handmade graphic depictions of mitotic chromosomes by Walther Flemming and meiotic chromosomes by Walter Sutton provided an early record of the physical path of chromosomes during cell division. The physical movement of chromosomes could then be correlated with cells’ patterns of genetic inheritance. Meiosis is important because it ensures that all organisms produced via sexual reproduction contain the correct number of chromosomes. Meiosis also produces genetic variation by way of the process of recombination. Later, this variation is increased even further when two gametes unite during fertilization, thereby creating offspring with unique combinations of DNA. This constant mixing of parental DNA in sexual reproduction helps fuel the incredible diversity of life on Earth. In 1902 American scientist Walter S. Sutton reported on his observations of the action of chromosomes during sperm formation in grasshoppers. Sutton had observed that, during meiosis, each
