Question

Quizplus · Accepted Answer

A recessive allele will only be expressed if it is present on both chromosomes of a homologous pair. If a dominant allele is present, it will be expressed regardless of whether the other allele present is dominant or recessive. Incomplete dominance describes a situation where the heterozygote expresses an intermediate phenotype between the two homozygotes. Phenotypic refers to the observable physical characteristics of an organism, not to a specific type of allele. Autosomal refers to genes located on the non-sex chromosomes.
