Es führt dazu, dass bei bestimmten Genen das Allel eines Elternteils inaktiviert ist ("Gen-Silencing") und daher nur das Allel des anderen Elternteils exprimiert wird.

[65] Inherited imprinted genes of offspring are believed to be monoallelic expressions. A single locus will entirely produce one's phenotype although two alleles are inherited. 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.

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 In diploid organisms (like humans), the somatic cells possess two copies of the genome, one inherited from the father and one from the mother.
