In humans, is a stomach (somatic) cell haploid or diploid?
A
Haploid (n)
B
Triploid (3n)
C
Diploid (2n)
D
Aneuploid by default in all tissues
Verified step by step guidance1
Understand the definitions of ploidy: Haploid (n) means having one set of chromosomes, diploid (2n) means having two sets, triploid (3n) means three sets, and aneuploid refers to an abnormal number of chromosomes that is not an exact multiple of the haploid number.
Recall that in humans, the haploid number (n) is 23 chromosomes, which is the number found in gametes (sperm and egg cells).
Recognize that somatic (body) cells in humans contain two sets of chromosomes, one inherited from each parent, making them diploid (2n), which totals 46 chromosomes.
Note that aneuploidy is a condition where cells have an abnormal number of chromosomes, but this is not the default state for all tissues; normal somatic cells are diploid.
Conclude that since stomach cells are somatic cells, they are diploid (2n), containing two complete sets of chromosomes.
