In the context of meiotic genetics, how many chromosomes are present in a typical human skin cell (a diploid somatic cell)?

• A. 48 chromosomes
• B. 92 chromosomes
• C. 46 chromosomes
• D. 23 chromosomes

Answer: (C)

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 (n) for humans is 23, which represents the number of chromosomes in gametes (sperm or egg cells).
3. Since somatic cells are diploid (2n), multiply the haploid number by 2 to find the total number of chromosomes in a typical human somatic cell.
4. Express this calculation as an equation: \(\text{Diploid number} = 2 \times n = 2 \times 23\).
5. Conclude that the total number of chromosomes in a typical human skin cell is 46 chromosomes.
