Best Answer: In humans, you would find 23 chromosomes in a sperm cell; 23 chromosomes in an egg cell; and 46 chromosomes in a white blood cell. All human body cells contain 46 chromosomes (two sets of 23 chromosomes). Only the gametes (i.e., the sperm & eggs) contain 23 chromosomes (one set of 23 chromosomes) because two gametes combine to form a new person with 46 chromosomes in his body cells. Body cells grow and reproduce by the process of mitosis.
exists and is an alternate of . Haploid, or gametic, human Cells have a chromosome number of n which is 23 individual chromosomes. The Gametic human sperm Cell has the chromosome number n = 23 [unpaired] chromosomes; in the also gametic human Oocyte (egg Cell), n also = 23.
