Answer #1

A) True, during S phase of cell cycle before cell division, Replication of DNA from the normal 2C takes place to yield 4C DNA content. Therefore in meiosos 1 stages the cell is 2N and 4C, before cell division.

B) True The cell is still 2N 4C, the homologous chromosomes have separated but the cell is still one

C) True, At the end of meiosis 1 we get two cells with 1N 2C, which continues in meiosis 2 (which is similar to mitosis)

D) True, gamete formed at the end of meiosis 2 has 1N and 1C.
