In a species with sex role reversal, males contribute more parental investment than females. In this species, you could also predict that

A) there will be more sexually active males than females.
B) there will be equal reproductive variance in males and females.
C) females are more likely to be larger and have ornaments to compete for mates.
D) sexual selection will be weaker than natural selection.

In species with sex role reversal, where males contribute more to parental investment, females often compete for mates. This competition can lead to females developing larger sizes and ornaments, traits typically associated with males in species where males compete for females. This is because the sex that invests less in offspring (in this case, females) is often more competitive for mating opportunities.
