Question

Condensation of chromosomes occurs in
(a) prophase I (b) prophase II
(c) anaphase (d) metaphase

Answer 1

Answer:

Condensation of chromosome occur in mitosis in prophesy.

Answer 2

Answer is option "a"

Explanation:

• Prophase I includes the pairing of homologous chromosomes and cross over. Anaphase I and anaphase II include separation and movement of homologous chromosomes and sister chromatids to opposite poles respectively. Prophase II is marked by condensation of chromatin material. Homologous chromosomes align themselves at cell's equator during metaphase I.  
• Condensation of chromatin occurs during the prophase stage. In meiotic cell division, the mother cell divides twice after one round of replication. In meiosis, condensation occurs during prophase I which is long and complex stage. Condensation also occurs in prophase II, even though prophase II is not elaborate as prophase I.
• Hence, the right answer is option a "prophase i".
