In humans the number of tetrads formed during mitosis is___________?
Correct answer: C. 0
- A. 23
- B. 46
- C. 0
- D. 4
Explanation
A tetrad is formed during prophase I of meiosis when homologous chromosomes pair, with each homolog consisting of two chromatids. Mitosis does not involve pairing of homologous chromosomes, so no tetrads are formed in human mitosis. Students may choose 23 or 46 by confusing chromosome number with the number of homologous pairs involved in tetrad formation.
