Imprinting affects the phenotype when
WitrynaRecessive alleles are only expressed when no dominant allele is present. In most sexually reproducing organisms, each individual has two alleles for each gene (one from each parent). This pair of alleles is called a genotype and determines the organism's appearance, or phenotype.

C)one allele is imprinted and the other is inactivated or deleted. D)an embryo arises from two female genomes or two male genomes. WitrynaGenomic imprinting is the biological process whereby a gene or genomic domain is biochemically marked with information about its parental origin. Genomic imprints may be covalent (DNA methylation) or non-covalent (DNA-protein and DNA-RNA interactions, genomic localization in nuclear space), and the process of imprinting encompasses …
