Sex determination at birth is decided on the chromosomes the baby has. A female has two X chromosomes, whereas a male has one X and one Y chromosome.
According to Medline Plus, in every cell, humans possess 23 pairs of chromosomes, among which the sex chromosomes constitute one pair. The X chromosome, comprising roughly 155 million DNA base pairs, makes up around 5% of the total DNA in cells.
The Y chromosome extends over more than 59 million DNA building blocks (base pairs) and accounts for nearly 2% of the total DNA found in cells.
However, according to The Conversation, the Y chromosome is degrading at a concerning rate.
