Which of the following comparisons between natural selection and
sexual selection is FALSE?
Under natural selection, fitness is compared across all
individuals; in sexual selection comparisons of fitness are only
relevant among individuals within a sex (e.g., males or females
only)
Both natural and sexual selection require variation in traits
that affect fitness.
Variation underlying traits must have a genetic basis and be
heritable under both natural and sexual selection.
Under natural selection, fitness is measured only by survival,
whereas under sexual selection fitness is defined by offspring
number..
