How many chromosomes are present in each human somatic cell?

Previous problemNext problem

Verified step by step guidance

Understand the concept of somatic cells: Somatic cells are any cells forming the body of an organism, excluding germ cells which are involved in reproduction.

Recognize that human somatic cells are diploid: This means they contain two sets of chromosomes, one set inherited from each parent.

Identify the total number of chromosomes in human somatic cells: Humans have 23 pairs of chromosomes, which totals to 46 chromosomes in each somatic cell.

Differentiate between autosomes and sex chromosomes: Out of the 23 pairs, 22 pairs are autosomes and the 23rd pair consists of sex chromosomes (XX or XY).

Conclude that the correct number of chromosomes in human somatic cells is 46, based on the diploid nature and the pairing of chromosomes.
