Question

Which of the following statements about genomic imprinting is FALSE? A minority of genes in the mammalian genome are imprinted. For a maternally imprinted gene, the copy inherited from the father is expressed only in his male offspring. According to the genomic conflict theory of imprinting, paternally imprinted genes encode proteins that, when expressed, restrict embryonic growth. Imprinting evolved at least twice: in mammals and in flowering plants. Offspring that inherit a mutant copy of a maternally imprinted gene from their father will have a mutant phenotype.
