Two populations of the same animal species live in separate habitats. Each population initially contains the same number of individuals. Population P reproduces asexually; population Q reproduces sexually.
After several generations, Q contains more individuals than P.
Which conclusion is justified?
survival and reproductive success can sometimes outweigh a faster reproductive cycle
sexual reproduction must have a shorter reproductive cycle in every habitat
asexual reproduction must produce much more genetic variation in every habitat
survival depends only on how many parents are needed for reproduction
