Chapter 11: Inherited Traits A. Mendel and Pea Plants Plants were self-fertilizing, producing both female and male gametes (sperm and egg) Patterns in traits told Mendel about inheritance (heredity) recognizing dominance and recessiveness in traits B. Theory of Segragation (sister chromatids) Diploid cells have pairs of genes on homologous chromosomes. End up in different gametes because of separation during meiosis Punnett-squares, and test crosses are used in prediction and showing possibilities of offspring Used monohybrid crosses to show how genes are segregated C. Theory of Independent Assortment (homologous pairs) Contributes to genetic variability due to the random orientation of homologous pairs of chromosomes at the metaphase plate during meiosis I. There is a fifty-fifty chance that a particular daughter cell of meiosis I will get the maternal chromosome of a certain homologous pair and a fifty-fifty chance that it will receive the paternal chromosome. Each homologous pair of chromosomes segregates independently of the other homologous pairs during metaphase I. Uses dihybrid crosses to show how pairs of genes are sorted into gametes
