Guida verificata passo dopo passo1
Understand the term 'somatic cells': Somatic cells are any cells forming the body of an organism, excluding germ cells (sperm and egg cells). In humans, somatic cells are diploid, meaning they contain two sets of chromosomes.
Recall the basic chromosome number in humans: Humans have a total of 46 chromosomes in their somatic cells. This includes 22 pairs of autosomes and 1 pair of sex chromosomes.
Consider the diploid nature of somatic cells: Each somatic cell has two sets of chromosomes, one inherited from each parent. This results in a total of 46 chromosomes.
Differentiate between somatic and gametic cells: Gametic cells (sperm and egg) are haploid and contain only 23 chromosomes, which is half the number found in somatic cells.
Verify the options given: Among the options provided (92, 44, 23), the correct number of chromosomes in human somatic cells is 46.
