Maybe this genetic study can be taken as a prototype to understand cultural traits too. How man created things like male god/s have negative effect on females or how patriachal ideals get perverted expression among females.
This battle, observed across many species and known as intralocus sexual conflict, happens when the genes for a trait which is good for the breeding success of one sex are bad for the other -- sparking an 'evolutionary tug-o-war' between the sexes.
It has previously been thought these issues were only resolved when the trait in question evolves to become sex-specific in its development -- meaning the trait only develops in the gender it benefits and stops affecting the other.
However, a new study by the universities of Exeter (UK), Okayama and Kyushu (both Japan) published Nov. 4 in Current Biology shows this doesn't always bring an end to conflict -- as even when the trait becomes sex-specific, knock-on effects can still disadvantage the other sex.
Kensuke Okada, also from Okayama University, said: "The view that sex-limited trait development resolves this kind of genetic battle of the sexes is based on the assumption that traits are genetically independent of each other, which is frequently not true.Via Science Daily
"What we're seeing here is that genetic architecture can provide a general barrier to this kind of conflict resolution."
