Document Summary
A. scientist and mathematician, augustinian monk: mendel"s law of inheritance. 1. character- heritable feature that varies among individuals, such as flower color. 2. trait-each variant for a character, such as purple or white. 3. short generation time, large number of offspring, character that occurred in two distinct alternating forms, true breeding over many generations. 2. if the two alleles t locus differ than one dominant determines the. 3. two alleles for a heritable character segregate during gamete formation and copies: two alleles appearance, the other, recessive has no noticeable effect end in different gametes. 1. homozygote- organism that has a pair of identical alleles for a gene. 2. heterozygote- organism that has two different alleles for a gene. G. the law of independent assortment- two or more genes assort independently, each pair of alleles segregates independently of any other pair of alleles during gamete formation. 1. incomplete dominance- mix of two diff traits (pink) 2. codominance- both phenotypes observed at once (has red and white)
