Short / Long Answer Type Questions :
During mitosis sister chromatids separate and migrate to opposite poles. Why does this- not occur during meiosis I ?

Answer 1

During mitosis, there is a separation of chromatids as to maintain the same number of chromosomes in both parent and daughter cells whereas in meiosis the chromosomes separate as it is a reductional division in which the number of chromosomes is reduced to half after first meiotic division.

so to reduce the DNA content to half the chromosomes separate attached to their centromere rather then separation of chromatids.
