Document Summary

This hypothesis proposes that genetic material contributed by each parent mixes in a manner analogous to the way blue and yellow paints blend to make green. With blending inheritance, a freely mating population will eventually give rise to a uniform population of individuals. Genes can be sorted and passed on, generation after generation, in undiluted form: modern genetics began in an abbey garden, where a monk named. Gregor mendel documented a particulate mechanism of inheritance. Pea plants are available in many varieties with distinct heritable features, or characters, with different variant traits. Mendel could strictly control which plants mated with which. Each pea plant has male (stamens) and female (carpal) sexual organs. In nature, pea plants typically self-fertilize, fertilizing ova with the sperm nuclei from their own pollen. However, mendel could also use pollen from another plant for cross-pollination: mendel tracked only those characters that varied in an either-or manner, rather than a more-or-less manner.
