ANTH 2700 Chapter Notes - Chapter 2: Gregor Mendel, Mendelian Inheritance, Phenylthiocarbamide
Document Summary
Blending theory: an early and incorrect idea that the inherited characteristics of offspring are intermediate between maternal and paternal genetic characteristics. True-breeding: showing the same traits without exception over many generations. Hybrids: individuals that are the result of a cross or mating between two different kinds of parents. Dominant: the trait that is seen in the hybrid is said to be dominant. Recessive: the trait that is not seen in the hybrid is said to be recessive. Model: representation of a phenomenon on which tests can be conducted and from which predictions can be made. Principle of segregation: in the formation of sex cells, the process in which paired hereditary factors separate, forming sex cells that contain either one or the other factor. Back cross: the process of crossing a hybrid with its homozygous recessive parent. Principle of independent assortment: differing traits are inherited independently of each other. Phenotype: the observable and measurable characteristics of an organism.
