For example, the gene encoding insulin-like growth factor 2 (IGF2/Igf2) is only expressed from the allele inherited from the father. Although imprinting accounts for a small proportion of mammalian genes they play an important role in embryogenesis particularly in the formation of visceral … Zobacz więcej Genomic imprinting is an epigenetic phenomenon that causes genes to be expressed or not, depending on whether they are inherited from the mother or the father. Genes can also be partially imprinted. … Zobacz więcej That imprinting might be a feature of mammalian development was suggested in breeding experiments in mice carrying reciprocal chromosomal translocations. Nucleus … Zobacz więcej Imprinting may cause problems in cloning, with clones having DNA that is not methylated in the correct positions. It is possible that this is due to a lack of time for reprogramming to be completely achieved. When a nucleus is added to an egg during Zobacz więcej In diploid organisms (like humans), the somatic cells possess two copies of the genome, one inherited from the father and one from the mother.
