But, it was not until the early 1900s that any scientific studies were done of the phenomenon. Austrian naturalist Konrad Lorenz became the first to codify and establish the science behind the imprinting process. Lorenz found that when young birds came out of their eggs they would become attached to the first moving object they encountered. In most cases in the wild, that would be their mother.
In genes that undergo genomic imprinting, the parent of origin is often marked, or âstamped,â on the gene during the formation of egg and sperm cells. This stamping process, called methylation, is a chemical reaction that attaches small molecules called methyl groups to certain segments of DNA.nly a small percentage of all human genes undergo genomic imprinting. Researchers are not yet certain why some genes are imprinted and others are not. They do know that imprinted genes tend to cluster together in the same regions of chromosomes.
