This is certainly As an illustration the case if both of those homologs of chromosome 15 originate from the identical parent, a situati

In a little subset of mammalian genes, one of the two inherited copies (alleles) is switched off. Which allele is issue to “genomic imprinting” is depending on whether or not it absolutely was inherited with the mom or the father. Genomic imprinting is actually a developmentally identifi
