Solution

The correct option is A 5
Metaphase I of meiosis I
  • The homologous chromosomes are arranged on the equatorial plate during metaphase I.
  • In the question, at this stage, the cell has 10 chromosomes (5 pairs of homologous chromosomes) arranged on the metaphase plate.
  • This is followed by cell division and the homologous chromosomes get segregated into the two haploid daughter cells (each daughter cell will have only 5 chromosomes).
Metaphase II of meiosis II
  • During metaphase II, the chromosomes align on the equatorial plate.
  • Since the daughter cells only have 5 chromosomes at this stage, the number of chromosomes at the equatorial plate during metaphase II will be 5.
