Gregor Mendel found the patterns of simple inheritance in 1860 which are the basic principles scientists still use today. He identified the hereditary unit, genes. The principle of segregation states that during the formation of gametes, the two traits carried by each parent separate. This can be shown in the following figure:
Mendel's principle of independent assortment states that during gamete formation, the alleles of a gene for one trait (Tt), segregate independently from the alleles of a gene from another trait (Yy). This principle applies when a cross takes place between two indivi…
