Document Summary

3. 1 gregor mendel discovered the basic principles of heredity. Used the pea plant pisum sativum bc it was: easy to cultivate, had it in his garden, peas grow rapidly (1 generation per year) He used 7 characteristics of pea plants to study: 1) seed (endosperm) color. Axial (along stem) terminal (tip of stem: 7) stem length. Unlike other investigators who described the results of the crosses, mendel formulated hypotheses based on initial observations and then conducted additional crosses to test his hypothesis. Genes come in diff versions called alleles in mendels crosses, seed shape was determined by a gene that exists as. A genotype is a set of alleles that an individual organism possesses. A diploid organism with a genotype that has 2 identical alleles is homozygous for that locus. A diploid organism with a genotype that has 2 different alleles is heterozygous for that locus.
