The sex ratio is low owing to the inherent bias in the number of sperm

1.	The sex ratio is low owing to the inherent bias in the number of sperms that carry Y chromosome.(a) True(b) FalseThe question was asked by my college director while I was bunking the class.My doubt stems from Human Reproduction topic in section Human Reproduction of Biology – Class 12
Answer» Right OPTION is (b) False The best explanation: The HUMAN males have XY as their sex chromosomes. Thus upon undergoing meiosis, the PROBABILITY of sperm having an X chromosome is the same as that of having a Y chromosome. There is no natural bias here. The lower sex RATIO hence cannot be accounted to such a biological phenomenon.
