      Hi folks!

      First of all, great forum!
      I have a question which I know is stupid, but I have to aks none the less, because it’s been bugging me a lot.

      Why are cells in interphase (before S-fase, eg right after mitosis) called diploid cells??? As far as I know, diploid means double set of chromosomes. Is there a double set of chromosomes in eg somatic cells? Because I thought that during anaphase a chromosome was separated into two one-chromatide chromosomes and that "double set" ment a two-chromatide chromosome.

      Would appreciate any help here!

      Diploid is in comparison to the gamete. After the S-phase, you have double the double, 4X DNA compared to gamete.
