The Principle of Segregation. The principle of segregation says that in diploid organisms genes come in pairs and that when gametes get produced each gamete gets one gene at random from each gene pair but not both. When developing this idea Gregor Mendel conducted a series on monohybrid crosses using pea plants.

Monohybrid cross: A monohybrid cross is a cross in which the breeder starts out with parents that are true breeding for alternate forms of a characteristic, for example flower color.
