How many genes does a female have for blood clotting?

A female typically has two copies of each gene, just as males do. This is because during the development of gametes (eggs and sperm), the cells divide in a way that ensures that each cell receives one copy of each gene. Therefore, if there are genes for blood clotting, a female would have two of those genes, just like a male.

However, it's important to note that females can be carriers of certain genetic disorders that affect blood clotting, such as hemophilia, due to the presence of a mutated copy of the gene on one of their chromosomes.
