Document Summary

Chapter 14: the basics of mendelian genetics. Gregor mendel: father of genetics , austrain monk, ~1860: breeding experiments in monastery garden. Mendel started with strains of peas with variable characters: character: feature that differs between individuals. Example: flower color: trait: differences in a character, eg. , purple flowers and white flowers . Starting strains were obtained from seed suppliers and were true-breeding: true-breeding: all individuals are identical, and self-fertilization gives rise to offspring like parents, generation after generation. Peas will self-fertilize, but can be made to hybridize: stamens (male organs) removed to prevent self-fertilization, pollen (male gametes) transferred from white to purple. * hybridize: produce offspring between genetically different strains. Monohybrid cross: a mating in which one character is followed. Nomenclature: p (parental) generation, f1 (first filial): offspring of the p mating, f2: offspring of an f1 mating, x indicates a mating, or a cross.
