Sep. 8th, 2015 06:54 pmPartial dominance: when one allele partly exhibits its phenotype in a heterozygous individual.
Codominance: when both alleles fully exhibit their phenotypes in a heterozygous individual.
Blood types show codominance, as when both A and B antigens are formed.
Polymorphy: when multiple alleles are present in appreciable frequencies in a population.
Epistasis: When one allele prevents the phenotypic expression of another allele. Since this has to do with pathways, a recessive allele can be epistatic over a dominant allele, or vice versa.
Pleiotropy: When one genotype corresponds to multiple phenotypes.
