Why do chromosomes come in pairs?

Answer 1

Chromosomes come in pairs as a result of sexual reproduction. In humans, one set of 23 chromosomes comes from your mother and one set of 23 comes from your father. When the sperm fertilizes the egg, the two sets of chromosomes come together to make the zygote, which has two sets of 23 chromosomes, for a total of 46. All the body cells of a human have the same number of chromosomes, which is 46.

Answer 2

Chromosomes come in pairs because one set is inherited from the mother and the other set is inherited from the father. This pairing ensures genetic diversity and allows for the exchange of genetic material through processes like recombination during reproduction. It also helps maintain genetic stability by providing a backup copy of each chromosome.
