उत्तर
XY chromosomes are present in male children. A boy is born when sperm from a Y chromosome unites with an ovum, whereas a girl is born when sperm from an X chromosome fuses with an ovum. This implies that the father cannot pass on the X chromosome to the son. The mother gives him the X chromosome.
