Thread: Genomic imprinting in humans

    I've just been doing some reading in my textbook (Biology, an Australian Focus, 4th ed) and came across imprinting in autosomes (non-sex chromosomes). The textbook describes that imprinting in relation to autosomes, is where there is inactivation of a small number of genes, and how it's not a problem as the homologous chromosome from the other parent does not have the same deactivation. Is this determined randomly or are there processes that determine that the same inactivated gene is not deactivated on both chromosomes? Or is it just simply inherently rare?

    P.S I originally started with a completely more confused stance, but in the process of writing my question, discovered my error and my problem was solved before I even posted it :P (I got mixed up between X-chromosome imprinting and non-sex chromosome imprinting).

    I can never know I'm right, but I can know that I'm wrong.
