BIOL 1100 Lecture Notes - Lecture 20: Pea, Walter Sutton, Mendelian Inheritance
Document Summary
Gregor mendel worked out rules of inheritance through series of experiments on garden peas; walter sutton and boveri formulated the chromosome theory of inheritance (meiosis causes the patters of inheritance that mendel observed) Genetics: branch of biology that focuses on inheritance of traits: uses model organisms (conclusions drawn from them can be applied to other species) - dr. qi (arabidopsis) plant. Heredity: the transmission of traits from parents to their offspring. Mendel chose the common garden pea because it is easy to grow, short reproductive cycle, produces large numbers of seeds, its mating are easy to control, its traits are easily recognizable. How did mendel arrange matings: peas pollinated themselves (self-fertilization/selfing) Mendel worked with pea: seed shape/color, pod shape/color, flower color/pod position, stem length: phenotype: observable features (2 distinct for each of 7 traits, pure lines - identical offspring when self-pollinated (homozygous) Used to create hybrids (crossing 2 different pure lines)
