The Origins of Genetics

Traits and heredity patterns were observed by Gregor Mendel's careful analysis of genotypes and phenotypes in monohybrid and dihybrid crosses. Mendel's discoveries improved the understanding of genetic patterns, while providing a way to predict the physical traits of future generations. Using probability to predict ratios, the chances of specific traits being passed from one generation to the next can be calculated. Because of Mendel's discoveries, heredity can be explained at a molecular level. Scientists still use the work of Mendel to make future advancements in the field of genetics.
