Genomic imprinting is an inheritance process independent of the classical Mendelian inheritance. It is an epigenetic process that involves DNA methylation and histone methylation without altering the genetic … 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 Unfortunately, the relationship between the phenotype and genotype of imprinted genes is solely conceptual. The idea is frameworked … Zobacz więcej Imprinting may cause problems in cloning, with clones having DNA that is not methylated in the correct positions. It is possible that … Zobacz więcej A similar imprinting phenomenon has also been described in flowering plants (angiosperms). During fertilization of the egg cell, a second, separate fertilization event gives rise to the endosperm, an extraembryonic structure that nourishes the embryo in … 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 … Zobacz więcej That imprinting might be a feature of mammalian development was suggested in breeding experiments in mice carrying reciprocal chromosomal translocations. Nucleus transplantation experiments in mouse zygotes in the early 1980s confirmed that … Zobacz więcej In insects, imprinting affects entire chromosomes. In some insects the entire paternal genome is silenced in male offspring, and thus is involved in sex determination. The imprinting produces effects similar to the mechanisms in other insects that … Zobacz więcej
