Document Summary
Male semen is magical and increase women semen. Female just held the little person to grow. Eve held 200 million generations in her ovaries. Early bio thought genetics were like paint. Black + white horse = grey horse. Lifetime of observations of hair color and other features for a list a natural variation. Genetic material contributed by the two parents mixes. Like blue and yellow paints make green paint. Everyday observations and animal breeding experiments contradicted. Failed to explain traits skipping a generation. Parents pass discrete units (genes) that can retain separate identities of offspring. Genes can be shuffled and passed along in an undiluted. Developed his theory before chromosomes were under a microscope. First born got estate but second became a teacher or a monk. Inheritance is governed by factors that each parent passes to the children. Factors separate when the gametes are formed and only one factor of each pair is present in each gamete.
