Within a given species, which two types of cells have the equivalent amounts of dna?
kiruha [24]
The original question has a set of choices. This is within the context of cell division. The choices are:

A. A cell in G1 of interphase and a cell in G2 of interphase
B. A cell in G1 of interphase and a cell immediately after the completion of meiosis II
C. A cell in G1 of interphase and a cell in metaphase II of meiosis
D. A cell in G2 of interphase and a cell in metaphase II of meiosis
<span>E. None of the above.
</span>
The correct answer is C. A cell in G1 is diploid and the cell in meiosis II is haploid but the amount of DNA still equivalent as each chromosome in the haploid cell consists of two chromatids. G2 cells already had been through the S phase therefore the genetic material is already doubled. A cell immediately after meiosis II has half the genetic material.
