Document Summary
Individual (incl. kin to avoid inbreeding) and sexual recognition (sexual imprinting) is important o: identification of good genes cues are important: phenotype. If a female coyote spends too much time around stray dogs, they can be impregnated by dogs. their own species but to males of another species. What males want and what females want. Men and women do not want the same thing. What females want and what is actually fit . What males want and what is actually fit . Females in birds and mammals ((and actually most vertebrates) typically invest more energy and time in gametes than males. Males have important secondary sexual characteristic called epigametic sexual characteristics to influence female choice. Those characteristics are used in displays to showoff and impress the females. The basic assumption is that females are strongly attracted to epigametic sexual characteristics that are highly correlated with good health (immune system integrity) and good reproductive capability (reproductive system integrity).
