- There are a small number of genes in which the maternal or paternal copy that an organism inherits is methylated. In one case in mice there are known mutations in the gene. If a mouse inherits a mutated gene from its mother, the mouse is normal. However, if the mouse inherits a mutated gene from its father, the mouse is much smaller than normal. Based on this information which allele is normally methylated, the paternal allele or the maternal allele?
