In humans no of tetrads formed during mitosis is __________?
Correct answer: C. 0
- A. 23
- B. 46
- C. 0
- D. None of These
Explanation
Tetrads form in prophase I of meiosis when homologous chromosomes pair and undergo crossing over. Mitosis does not pair homologous chromosomes, so the number of tetrads formed during human mitosis is 0. Students may choose 23 by confusing tetrads with the 23 pairs of human chromosomes.
