A- Parental investment is high in females than male

Reason - Eggs are much larger than sperm.

Females are responsible for gestation and lactation.

B - Parental investment is high in males than female - very rare

C- Parental investment of males is equal to female

Degree of mate choice should be equal between the sexes.

No sexual dimorphism
