How many chromosomes do most human cells have? (a) 12, (b) 23, (c) 46, (d) 69.

Answer :

Option C, In humans, there are typically 46 chromosomes, or 23 pairs, in each cell. There are 22 of these pairs, known as autosomes, and they have a similar appearance in both sexes.

The number of chromosomes in sperm or egg cells, often known as gametes, is sometimes referred to as haploid. In humans, gametes are haploid cells with 23 chromosomes—one of each chromosomal pair found in diplod cells—and are hence haploid. For humans, each diploid cell has 46 chromosomes. There are 22 pairs of autosomal, or non-sex, chromosomes among them, and two of them determine sex. Two times as many chromosomes as those in a haploid cell, or 2n, make up the total number of chromosomes in diploid cells (n).
