In humans, how many chromosomes are present in each somatic (body) cell?
A
44 chromosomes
B
48 chromosomes
C
46 chromosomes
D
23 chromosomes
Verified step by step guidance1
Understand that humans are diploid organisms, meaning each somatic (body) cell contains two sets of chromosomes—one set inherited from each parent.
Recall that the total number of chromosomes in a human somatic cell is the sum of these two sets.
Know that each set, called a haploid set, contains 23 chromosomes, which are found in human gametes (sperm and egg cells).
Calculate the total number of chromosomes in a somatic cell by multiplying the haploid number by 2: $2 \times 23$.
Conclude that the total number of chromosomes in each human somatic cell is 46.
