<span>All of the above apply EXCEPT incomplete dominance. </span>
multiple alleles - Blood type has three alleles (more than two): A, B, O
<span>codominance - The A and B alleles are
codominant to each other. Neither allele is dominant and both are
expressed in the phenotype of the heterozygote (AB). In other words,
individuals with blood type AB have the characteristics of both type A
and type B blood. </span>
<span>principle of dominance - Both the A and B alleles are dominant to the O, which is recessive. </span>
<span>segregation of alleles - Alleles for
blood type separate (orr segregate) during gametogenesis (gamete
formation) and end up in different gametes, so that one allele is
inherited from each parent. </span>
<span>(Note: Incomplete dominance is not
demonstrated. It is also called partial dominance and is a form of
intermediate inheritance in which one allele is not completely expressed
over its paired allele. This results in a third phenotype in which the
expressed trait is a combination of the phenotypes. In sum, one trait
doesn't completely dominate over the other allele, thereby creating a
new phenotype. This is not exhibited in blood types.)</span>
