Question

After completing meiosis II, human sex cells have a total of _____ chromosomes

Answer 1

Ans.

Meiosis involves a type of cell division in sexually reproducing organisms that results in formation of four daughter cells from a single parent cell, having half of the genetic material as in parent cell. Meiosis is divided into meiosis I and meiosis II.

In gamete forming cells of humans are diploid cells and have 23 pairs of chromosomes (or 46 chromosomes). Each gamete forming mother cell undergoes meiotic division to form haploid daughter cells or gametes, each with 23 chromosomes.

Thus, the correct answer is 'twenty-three' as there are 23 chromosomes present in human sex cells at the end of meiosis II.

Answer 2

After meiosis is complete, human sex cells (of the new cell) have a total of 46 chromosomes - 23 from the mother and 23 from the father.
