Sexual dimorphisms are described as arising particularly where there is more variability in:
ATotal population size
BYearly rainfall amount
CMale reproductive success
DFemale body size only
Answer & Solution
Correct answer: C. Male reproductive success
1. Dimorphism tracks how unevenly reproduction is distributed.
2. Sexual dimorphisms arise in many populations, particularly animal populations.
3. They arise where there is more variability in the male's reproductive success.
4. That variability is greater than that of the females.
