Question

Separation of sister chromatids occurs during which stage of meiosis

Answer 1

Answer:

Separation of sister chromatids occurs during the Anaphase - II stage of meiosis

Explanation:

• Meiosis is also called reduction division because by it results in the reduction of the number of chromosomes in daughter nuclei
• A single meiotic division leads to the formation of 4 daughter nuclei, each with half the number of chromosomes as that present in the parent nucleus
• Meiosis is divided into two phases and consists of two occurrences of nuclear division and a single occurrence of cell division.
• The first nuclear division, termed Meiosis I, results in the separation of the homologous chromosomes
• Anaphase-I of Meiosis I results in the separation of the two homologous chromosomes but the sister chromatids remain attached at the centromere and move towards the same pole
• During Anaphase - II of Meiosis - II, the sister chromatids split at the centromere and each of the sister chromatids moves toward the opposite poles.
• These two instances of nuclear division (karyokinesis) result in the formation of four haploid daughter nuclei.
