It is like tossing a coin. Heads or tails. There are usually only 2 choices.
That said an animal's sex is often determined by the sex chromosomes it inherits. The new research reveals that species with X and Y sex chromosomes, including mammals, generally have female-skewed populations.
Species where males are the sex that has different sex chromosomes are significantly female-biased,
with adult sex ratios slanting more than 56 percent female. The human male has a Y chromosome that is much different than the female X.
Researchers suggest whichever sex has two different sex chromosomes may suffer a higher rate of mortality after birth.
