Metaphase-II of meiosis differs from metaphase-I in possessing

Options

  1. Asame number of chromosomes in cells and same number of chromatids in each chromosome
  2. Bhalf number of chromosomes in cells and half number of chromatids in each chromosome
  3. Chalf number of chromosomes in cells and same number of chromatids in each chromosome
  4. Dhalf number of chromosomes in cells and double number of chromatids in each chromosome

Correct answer

B. half number of chromosomes in cells and half number of chromatids in each chromosome

Step-by-step solution

In metaphase I of meiosis disjunction of chromosomal pair occurs and chromosome number is reduced to half, but each chromosome has two chromatids. In metaphase II centromere splits and chromatids are separated thus each chromosome has one chromatid.
