ANTHRO 7 Chapter Notes - Chapter 2: Mendelian Inheritance, Mitosis, Gamete
Document Summary
Variants: a number of traits with only 2 forms. Pea color was the trait he focused on. 1st = f0, 2nd = f1, 3rd = f2. Characteristics from 2 particles, one from mother, other from father (genes) Each gene is equally likely to be transmitted when gametes (eggs and sperm) are formed > independent assortment. Chromosomes > discovery allowed genetics to be understood better/located in cells and replicated during division that creates gametes. Ordinary cell division with division of nucleus > mitosis. Meiosis: cell division > produces gametes, 1/2 chromosomes are transmitted from. Original set is duplicated > daughters exact copy same chromosome when united. Dominant vs. recessive: d is shown as long as it"s present. Recombination: sexual reproduction shuffles genes that affect different traits > new combos > maintains variation. Segregates independently > don"t always effect one another when on different chromosomes. Links between location on the same chromosome alters the pattern of segregation.
