Document Summary
Units of inheritance exist and predicted their behavior in the formation of gametes. Transmission genetics: how genes are transmitted from parents to offspring. Mednel used a model experimental approach to study patterns of. Organism that was easy to grow and to hybridize artificially. Self-fertilizing in nature, but it is easy to cross-bread experimentally. Reproduces well and grows to maturity in a single season. Visible features, each represented by two contrasting forms or traits. Seed shape and color, pod shape and color, and flower color and position. True-breeding strains - those in which each trait appeared unchanged generation after generation in self fertilizing plants. Restricted his examination to one or very few pairs of contrasting traits in each experiment. Monohybrid cross: made by mating true-breeding individuals from two parent strains, each exhibiting one of the two contrasting forms of the character under study. Selfing: self-fertilization of individuals from this first generation. F2: individuals resulting from the selfed f1 generation.
