WebIntroduction. Genomic imprinting is the monoallelic expression of a subset of genes in a conserved, parent-of-origin fashion. This process is regulated by epigenetic mechanisms, including DNA methylation and histone modifications. 1 Complete loss of imprinting status, leading to either functional nullisomy or biallelic expression of specific imprinted genes, … WebFor example, Lorenz found that when a bird sexually imprints on a human, the bird will try to mate with a human — but not the one who raised it.
