Question

The number of chromosomes in normal humans is $46$. After meiosis in sperm production, the number of chromosomes and the number of resulting cells would be

• A. $46,2$
• B. $23,2$
• C. $46,1$
• D. $23,1$
• E. $23,4$

Answer 1

The correct option is E $23,4$

Meiosis is the reductional division that reduces the number of chromosomes to half in the daughter cells and makes total 4 cells per division. Meiosis in primary spermatocytes (2n=46) produces four sperms, each carrying 23 chromosomes. Thus, the correct answer is option E.
