The process of imprinting in nature
This process of erasure and reprogramming is necessary such that the germ cell imprinting status is relevant to the sex of the individual. In both plants and mammals there are two major mechanisms that are involved in establishing the imprint; these are DNA methylation and histone modifications. Visa mer 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. Partial … Visa mer Unfortunately, the relationship between the phenotype and genotype of imprinted genes is solely conceptual. The idea is frameworked using two alleles on a single locus and hosts three different possible classes of genotypes. The reciprocal heterozygotes … Visa mer 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 … Visa mer In diploid organisms (like humans), the somatic cells possess two copies of the genome, one inherited from the father and one from the mother. … Visa mer That imprinting might be a feature of mammalian development was suggested in breeding experiments in mice carrying reciprocal Visa mer Imprinting may cause problems in cloning, with clones having DNA that is not methylated in the correct positions. It is possible that this is … Visa mer A similar imprinting phenomenon has also been described in flowering plants (angiosperms).

For example, precocial baby birds (such as ducks, geese, and turkeys) begin the process of imprinting shortly after hatching so that they follow the appropriate adult, providing them with safety.
Webb1 okt. 2005 · One of the key elements of the imprinting mechanism is DNA methylation, controlled by DNA methyltransferase enzymes. Germ cells undergo reprogramming to ensure that sex-specific genomic imprinting is initiated, thus allowing normal embryo development to progress after fertilisation.
