Detailed explanation-1: -When a sperm and egg fuse, their genetic material combines to form one complete, diploid set of chromosomes. So, for each homologous pair of chromosomes in your genome, one of the homologues comes from your mom and the other from your dad.

Detailed explanation-2: -Among the many things parents hand down to their children are 23 pairs of chromosomes – those thread-like structures in the nucleus of every cell containing the genetic instructions for every person. We inherit a set of 23 chromosomes from our mothers and another set of 23 from our fathers.

Detailed explanation-3: -People usually have two copies of each chromosome. One copy is inherited from their mother (via the egg) and the other from their father (via the sperm). A sperm and an egg each contain one set of 23 chromosomes.

Detailed explanation-4: -And since we get 23 sets of chromosome from each parent, humans have 46 total chromosomes. This is notated as 2n=46. Therefore most cells in your body have 46 chromosomes in 23 homologous pairs, one chromosome from your mother (maternal chromosome) and one from your father (paternal chromosome).
