Is it the sperm or egg that determines twins?
Sperm contains either an X(female) chromosome or a Y(male) chromosome, whereas the egg contains only an X(female) chromosome. Neither the egg nor the sperm can be said to have a"sex." The combination of an X-bearing sperm with the (X-bearing) egg produces a female baby. The combination of a Y-bearing sperm with the (X-bearing) egg produces a male baby. It might seem that the man (sperm) that determines the sex of the baby, but this assumes that the egg is passive, accepting the first sperm to arrive at the egg. Some recent evidence indicates that this is not so. See the Wikipedia article on "Maternal influence on sex determination.
How many different combinations of sperms are possible in a human male?
There are only two possible combinations of sperm that a male can produce. A single sperm will either be X bearing or Y bearing. If an X sperm splits one egg, the result will be female. If a Y sperm splits the egg, the result will be male.
