Question

in human cells 2N = 46. how many chromosomes would you expect to find in a sperm cell? in am egg cell? in a white blood cell? Explain

Answer 1

Sperm=23

Egg cell=23

White blood cell=46

Step-by-step explanation:

During cell division Meiosis produce haploid number of gametic chromosome 23.

The somatic cell contains 46 chromosome i.e diploid chromosome number. During cell division in meiosis gametes cells contains haploid number-23 chromosome which is half of the somatic cell chromosome.

During conjugation, haploid chromosome is donated by each parent to give a diploid organism with 46 chromosome number.

White blood cell contains 46 chromosome because it doesn't undergo cell division it is a somatic cell.

Answer 2

There will be 23 chromosomes in a sperm cell, 23 chromosomes in an egg cell, and 46 chromosomes in a white blood cell

Step-by-step explanation:

Human cells are diploid in number i.e they exists in two basic sets (2N =46, where N is 23). So, cells of human body such as blood cells like white blood cells have two basic sets of chromosomes i.e 46 chromosomes, since they are produced by mitosis.

On the other hand, cells of humans involved in sexual reproduction such as the gametes (sperm and egg) have only one set of chromosomes since they are produced by meiosis - so they are haploid (N =23).
