Some basic principles of heredity were established by Gregor Mendel. In his experiments, he crossed large numbers of pea plants and then:
AMapped the location of various genes
BAnalyzed the mathematical ratios of certain traits in the offspring
CDissected the chromosome of the offspring
DDetermined how many genes had mutated
