Do males or females produce gametes?
Females generally produce a few large gametes, while males typically produce astronomical numbers of tiny gametes. 2) Investment. The disparity in gamete size sets the stage for sex differences in investment throughout the entire reproductive cycle.
Is the gamete produced by females?

Which gender has which gamete?
Here, females carry two X chromosomes (XX) and only produce gametes with X chromosomes. Males, on the other hand, carry only one X chromosome (XO) and produce some gametes with X chromosomes and some gametes with no sex chromosomes at all (Figure 5).
