If a female has XX and a male has XY, what do you think will be the outcome of 100 babies?

Fifty babies will be females while fifty babies will be males.

Explanation: A cross between XX and XY will yield 2 XX and 2 XY. This means that 50% of the offsprings are females while 50% of the offsprings are males. What this means is that fifty out of one hundred babies will be females while the remaining fifty will be males

See the punnett square attached for the details of the cross
