Question

explain how offspring and parents of organism reproducing sexually have the same number of chromosomes
​

Answer 1

Answer: Meiosis

Parent organisms have 23 pairs of chromosomes in each normal cell. But due to meiosis in sex gametes (sex cell), chromosome in each gamete is 23. 23+23=46. 46 chromosomes in offsprings. 23 from father 23 from mother

Answer 2

Explanation:

Parents and offspring have the same number of chromosomes because of meiosis.

It is a type of cell division in which the number of chromosomes is halved in the reproductive cells, so that on fusion of the gametes, the normal chromosome number is regained.

Extra information:

Meiosis is called reduction cell division because of the chromosome number being halved.

The halved chromosome number is also called haploid number, represented by n.

The normal chromosome number is called diploid number, represented as 2n.
