How many chromosomes are found in a typical human somatic cell?

• A. 23 chromosomes
• B. 46 chromosomes
• C. 48 chromosomes
• D. 44 chromosomes

Answer: (B)

In a typical human somatic cell, there are 46 chromosomes. This number is significant because humans are diploid organisms, meaning they inherit half of their chromosomes from each parent. The 46 chromosomes consist of 23 pairs, with one chromosome of each pair coming from the mother and the other from the father. Each pair includes one homologous chromosome from each parent, and the full set of 46 chromosomes contains both autosomes (the first 22 pairs) and sex chromosomes (the 23rd pair, which determines the biological sex of the individual). The presence of this specific number of chromosomes is essential for normal growth, development, and functioning, as they carry the genes that dictate the traits and characteristics of the organism. In contrast, the other options represent incorrect chromosome counts for human somatic cells, as they do not account for the diploid nature of human genetics.
