Unformatted text preview: Codominance: One allele is said to exhibit codominance with respect to another allele when each allele produces its full phenotype in the heterozygote. Polymorphism in the loosest sense means that there exists in a population more than one discretely different forms of a character. In the most qualified sense, polymorphism refers to the existence of more than one allele at a locus in a population. At least two of the alleles have to have a proportion greater than . 01. Multiple allelism refers to the existence of more than two alleles at locus. Usually, of course, MA means that a population has the strictest sense of polymorphism. May not necessarily be the case. The ABO blood type system in humans provides examples of poly, MA, dominances. HW: C3 p. 89 106 Skip recombination go to p. 112. (Section 3.5) 114: stop no cytoplasmic segregation. 116: Stop.
