... ascertained, one of the parental alleles is unmethylated and the other is heavily methylated. Possibly, the paternal allele of cottontail Impact may be exclusively expressed like rabbit Impact [12]. ... reliable. In species from the Glires clade, Impact bears a differentially methylated region, whereby the maternal allele is hypermethylated. Analysis of this regio...
