Imagine that for a maternally imprinted gene, allele a encodes an inactive version and allele A is the wildtype version. Do you expect the following individuals to exhibit an abnormal phenotype? Why or why not? a) a female of genotype Aa in which the wildtype allele came from her father? b) a male of genotype Aa in which the wildtype allele came from his mother?

Solution Summary

Imprinted genes are genes whose expression is determined by the parent that contributed them. Imprinted genes violate the usual rule of inheritance that both alleles in a heterozygote are equally expressed.
