People say there is evidence that humans basically imprint to some extent on the opposite sex parents so that if you, the traits that you look for in your partner or the traits you find attractive in the other, other sex are somewhat determined by your parents' traits. Sexual imprinting in juveniles is something that from a evolutionary perspective often makes a lot of sense. You're reared by individuals who were successful at reproducing. So by imprinting sexually on something that you've experienced in your early childhood, you're picking an individual that has attributes that probably made them successful at mating. Some of the earlier studies that were done in domesticated animals looked at the effects across fostering the two closely related species of sheep and goat. So giving nanny goats a young sheep to look after and giving female sheep young goats to look after. And the extraordinary thing about these studies is the orientation of the individuals later in life towards forming sexual partners was influenced by early life experiences and that's particularly strongly affected in the males and not in the females. So a belly goat brought up by a sheep. Well, the first few years of life prefer to mate with or select a female sheep to mate with rather than the female goat, which would be the correct species.
