Document Summary
What is the role of chance in heredity: napp presided over the monastery where mendel began his seminal genetic experiments in 1864. Mendel"s law of segregation: two alleles for each trait separate during gamete formation, two gametes, one from each parent unite at random during fertilization. Mendel"s experiments: the organism: the garden pea good because within a short amount of time he could obtain a lot of individuals. 1 self fertilization the egg and pollen come from the same plant cross-fertilization brushing pollen from one plant onto a female organ of another plant the ovary becomes the pea plant. Mendel"s law of independent assortment: during gamete formation, different pairs of alleles segregate independently of each other. 2: y is just as likely to assort with r as it is with r, y is just as likely to assort with r as it is with r.
