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 AND Explanation:
Classification is the orderly arrangement of organisms into groups based on their similarities. The modern method of classifying organisms was devised by Carolus Linnaeus. The characteristics used include:
- Anatomical structure- whether the organism is prokaryotic or eukaryotic
- Biological processes for example photosynthesis in plants and production of hormones.
- Cell structure
- Body type- unicellular or multicellular
- Mode of nutrition- heterotrophic or autotrophic
