If the DNA content of a diploid cell in the G1 phase is x, what would be the DNA content of the same cell at metaphase I of meiosis?

  • A: 0.25x
  • B: 0.5x
  • C: x
  • D: 2x

Explanation

A diploid cell in G1 has a certain amount of DNA x . Before meiosis I, the cell goes through the S phase, where its DNA is replicated. Therefore, at metaphase I, the cell contains double the amount of DNA, which is 2x.
