Explanation:

The female has two X chromosomes; all egg cells normally carry a single X. The eggs fertilized by X-bearing spermatozoa give females (XX), and those fertilized by Y-bearing spermatozoa give males (XY). The genes located in the X chromosomes exhibit what is known as sex-linkage or crisscross inheritance.
