There are a few errors with the article. The ploidy of a cell undergoing mitosis does not change. Ploidy refers only to the number of chromosomes in the cell. Following S-phase the cell still has the same number of chromosomes (despite the fact the chromosomes now consist of two DNA molecules). The tissue discussed would contain cells with a DNA content of 2C and 4C, however ALL of these cells are diploid (none are tetraploid). Also, saying that the 4C cells have two genomes is misleading; it would make more sence to say that they have 4 haploid genomes... although it is of course best to say they have a DNA content of 4C. —Preceding unsigned comment added by 24.65.79.143 ( talk) 04:24, 6 September 2010 (UTC)
