Question

During meiosis, the content of DNA per
chromosome reduced half in
1) Anaphase – I 2) S - phase
3) Anaphase – II 4) Metaphase – I

Answer 1

Answer:

The correct answer is option A.

Explanation:

Chromosome number reduces to half during anaphase I of meiosis. The sister chromatids remain together while the homologous obtained from the other parent seperate. Kinetochore microtubules shorten, pulling homologous chromosomes to opposite poles. Non-kinetochore microtubules lengthen, pushing the centrosomes farther apart. The cohesin from the chromosome arms is degraded while the cohesin surrounding the centromere remains protected.

Answer 2

anaphase 1 .............
