Document Summary
Learned associations, such as appearances - innate preferences: female peacock can be raised in isolation and still choose the male with the largest tale. Sign of good genes honest signal: frogs with the deepest croak, male species that fight. In some species, mated males and females will form lasting pair bonds, living together before and long after copulation. Appetitive behaviour establish, maintain, or promote sexual interaction (leads up to the behaviour: a pro(cid:272)epti(cid:448)e fe(cid:373)ale rat (cid:373)ay approa(cid:272)h (cid:373)ales or perfor(cid:373) (cid:862)ear-(cid:449)iggli(cid:374)g. (cid:863, male appetitive behaviours include staying near the female, sniffing, singing, and nest- building. Copulation (coitus) involves one or more intromissions in which the male penis is inserted into the female vagina: following stimulation, the male ejaculates sperm-bearing semen into the female. Refractory phase follows after copulation, length varies with species: coolidge effect refers to the faster resumption of mating behaviour with a different partner.
