For thousands of years, humans have understood that characteristics such as eye color, hair color, or even flower color are passed from one generation to the next. The passing of characteristics from parent to offspring is called heredity.
Blending Theory of Inheritance
During Mendel’s time, the blending theory of inheritance was popular. This is the hypothesis that posterity have a mix, or blend, of the qualities of their folks. Mendel noticed plants in his own garden that weren’t a blend of the parents.
Genetics is the branch of biology that focuses on heredity in organisms.
Modern genetics is based on Mendel’s explanation of how traits are passed from generation to generation.
Mendel’s use of mathematics in his pea plant studies was important to the confidence he had in his results.
