Document Summary
Monohybrid crosses: mendel"s principles of : dominance, segregation. In peas, the structure of the flower enforced self-fertilization between the plans own male and. Mendel"s peas were highly in-bred: genetically similar for given traits. female gametes: therefore, the plants are said to be (cid:498)true-breeding. (cid:499) Mendel"s experiments were carefully designed so that he could study the transmission of one trait at a time. Homozygous: both alleles are identical (aa, aa, bb, bb) Heterozygous: the two alleles are different (aa, bb) Their immediate offspring represent the first filial (f1) generation. In a genetic cross the parents are referred to as the parental (p or po) generation. One of mendel"s first experiments: a monohybrid (single trait) cross. Each trait behaved the same way (table 3. 1) Each trait was controlled by a heritable factor that came in one of two forms: dominant, recessive. Dominant & recessive forms of the gene are alleles.
