How many times does DNA replicate during meiosis?
Once! Interphase is the stage at which Dna replicates itself. During Mitosis, there is one interphase. During Meiosis, there is also one interphase. We are trying to create 4 haploid cells in meiosis and there are two divisions. With that, we only need one interphase.
(Interphase II does not exist!)
Here you don't see two interphase, the stage at which DNA is duplicated. There is only one interphase at the very beginning of the cycle so we could have two divisions and create 4 haploid cells.
Hope this helped! :D
