A) polygenic inheritance
B) incomplete dominance
C) dominant-recessive inheritance
D) genomic imprinting

Question

Quizplus · Accepted Answer

Genomic imprinting is a phenomenon where the expression of a particular gene depends on whether it is inherited from the mother or the father. This is because certain genes are "marked" or imprinted with chemical tags that affect their expression, based on which parent they were inherited from. Polygenic inheritance refers to traits that are determined by the combined effects of multiple genes. Incomplete dominance refers to a situation where neither allele is dominant, and the phenotype is a blending of the two. Dominant-recessive inheritance refers to a situation where one allele is dominant over the other, and determines the phenotype in heterozygous individuals.
