>>11194685>What advantages or disadvantages would it produce?In the equilibrium the expected value of a female should be the same as the expected value of a male.
Now, the total offspring from all males in a population is the same as the total offspring from all females in a population, since offspring comes from one male+one female.
If there are more males than females, then it means that a female has lower expected offspring. However if a female is in some sense "cheaper" than a male, perhaps because it's more diminutive and requires less resources, then the lower amount of expected offspring can be balanced by lower resource requirements.
To give an example: Because more females then males are born females on average 1.7 children, while males have on average 2.3 children. Female cost 170k to bring to maturity and male costs 230k to bring to maturity.
