In humans, how many chromosomes are present in each typical somatic (body) cell?

• A. 92
• B. 44
• C. 23
• D. 46

Answer: (D)

Verified step by step guidance

1. Understand that human somatic cells are diploid, meaning they contain two sets of chromosomes—one set inherited from each parent.
2. Recall that the haploid number (number of chromosomes in gametes like sperm and egg) in humans is 23.
3. Since somatic cells have two sets, multiply the haploid number by 2 to find the diploid number: \(2 \times 23\).
4. Calculate the total number of chromosomes in a typical human somatic cell, which is the diploid number.
5. Recognize that this total corresponds to 46 chromosomes in each typical human somatic cell.
