Document Summary
Walter sutton & theodor boveri realized meiosis could explain mendel"s rules. Explains principle of independent assortment and principle of segregation. Other for wrinkled seeds: these alleles also segregate into different daughter cells during meiosis i, when homologous chromosomes separate. Physical allele separation during anaphase of meiosis i. If alleles for different genes are on different chromosomes, they assort independently of one another at meiosis i: physical basis for independent assortment. Over many meiotic divisions, four types of gametes will be produced in equal proportions. Chromosome theory of inheritance - mendel"s rules can be explained by the independent alignment and separation of homologous chromosomes at meiosis i. Sutton and boveri"s hypothesis that genes are located on chromosomes was untested. Possible to identify interesting phenotype variation among individuals: doesn"t have common phenotypic variants like mendel and his round/wrinkled seeds. Thomas hunt morgan instead had access only to flies with most common phenotype for each trait.
