The Y chromosome has surprisingly little information/genes in it. Basically it contains one gene that activates all of the male-only genes on other chromosomes. So no, maternal chromosomes/genes contribute to male genital formation too and half of your father’s chromosomes/genes (that affect genital formation) will not be inherited by you

Reply to As there is no genetic information regarding the looks of a penis in our mother, all the information about our penis comes from our father. Thus, there is an insane high probability that our penis looks like our father's penis. by Shreyash_Jha_5813
