Question

Quizplus · Accepted Answer

The presence of a group of antigens that determine blood type is an example of a multiple allele system, as there are three different alleles (A, B, and O) that can determine an individual's blood type. Semilethal alleles refer to alleles that have an intermediate effect on an organism's survival, sex-linked traits are genes located on the sex chromosomes, and incomplete dominance refers to a situation in which the heterozygous phenotype is intermediate between the homozygous dominant and homozygous recessive phenotypes.
