Question: Explain how sex determination take place in humans?

Sex determination in humans takes place at the genetic level and is based on chromosomes. Humans are born with 46 chromosomes, and the sex of an individual is determined by the 23rd pair of chromosomes. People who are XX are female, and people who are XY are male. The presence of the Y chromosome triggers male gonadal development, including testicle production and the production of male hormones; this leads to the development of male characteristics, such as facial hair and a deeper voice. The absence of the Y chromosome triggers female gonadal development, including the production of female hormones and the development of female characteristics, such as a higher pitched voice and the lack of facial hair.
