When male chickens inseminated female turkeys, both male and female embryos form, but the males are much less viable and usually die in the early stages of development.
In particular, they observed males, and females who had male spermalege structures, were inseminated less often than females with female spermalege structures.
Under scramble competition to inseminate females, the early matured males are smaller than the rest of the population and can attain the highest mating success.
The importance of these myths and their transmission is that they inseminate a particular self-image and world view, which forms a specific type of reading of, or relating to, reality.
