The diagram shows a cell of an organism formed by reduction division. What is the diploid number for this organism?
Correct answer: E. 44
- A. 10
- B. 20
- C. 30
- D. 40
- E. 44
Explanation
Haploid cells are formed by reduction division, which has half the number of chromosomes than diploid cells. To calculate the diploid number of cells just multiply the chromosome number in the haploid number by 2. So, 22x2=44.

About Chromosomes
Chromosomes are DNA-protein structures that carry genes and become visible during cell division. Coverage includes chromatin, centromeres, sister chromatids, homologous chromosomes, chromosome number, and the distinction between diploid and haploid cells, with links to DNA replication, mitosis and meiosis.
