Quizplus · Accepted Answer

A dominant allele will produce a phenotypical trait regardless of whether its pair is homozygous or heterozygous. In contrast, a recessive allele will only produce a phenotypical trait when both pairs are homozygous for the recessive allele. Imprinting refers to differential expression of alleles based on whether they were inherited from the mother or father, and an SNP (single nucleotide polymorphism) is a genetic variation that occurs when a single nucleotide in a DNA sequence is altered.
