Comments "Animals and their organs seem to know roughly what total cell mass they should have, rather than how many cells they should contain. The cells in a tetraploid salamander, for example, are twice the size of those in a diploid salamander (see below), yet the corresponding organs in the two animals are the same size because the tetraploids contain half as many cells as the diploids (primary source). Thus, the central question of size control is how total cell mass is determined."
