Chapter 10-genetics Genetics - selectively breeding for thousands of years. Plants were used to study genetics. They can be grown in large quantities, produce a lot of offspring, relatively short generation time, reproduce quickly, easy to see products. They have both male and female reproductive parts, makes self-pollination/self-fertilization. Anthers-pollen (male) Stigma- pollinated by pollen Joseph Kolreuter - originally the big guy in genetics. Proved: male & female parents contribute equally to the characteristics inherited by the offspring. (Meiosis proves this to be true). Proved by reciprocal cross: Equally contributed to the phenotype/offspring. Through the reproduction of the offspring theory of Gregor Mendel 1800s -pea experiments (disproved Kolreuter’s theory). Mendel picked characteristics that had distinguishable traits-a characteristic that is observable feature-what you are looking at. Character= shape. Shape= wrinkled or smooth.
