Why does mate choice copying exist?
Mate-choice copying has evolved to eliminate the possible costs—including time and energy —of mate-choice. The fact that mate-choice copying exists in various species is due to the differential abilities of females in choosing a desirable male with good quality genes.
Why females are usually more selective in choosing mates?
Females tend to be the choosier sex when it comes to selecting a mate, part- ly because males can produce millions of sperm, whereas females' eggs are few and far between. Thus, females may be more selective because they have more invested in each gamete and in the re- sulting offspring.
What are the two types of mate selection?
Two types of mate selection occur: intersexual selection (the choice of a mate where individuals of one sex choose mates of the other sex) and intrasexual selection (the competition for mates between species members of the same sex).
How does cryptic female choice work?
Females achieve cryptic choice through a variety of mechanisms, including by altering copulation duration and sperm transfer, ejecting sperm of non-preferred males and selective use of sperm of the preferred male to fertilize eggs [32,34,35].
