In meiosis 1, it is said that chromosome numbers become halved in the two daughter cells.
For example, in a 2n human cell there are 46 chromosomes.
During meiosis 1, the cell will undergo interphase and probably the S-phase, where chromosome number becomes duplicated.
Now the cell is 4n (i.e. 92 chromosomes). During anaphase 1, 46 chromosome out of 92 would go towards one pole and 46 would go opposite.
Thus the resulting two cells will have 46 chromosomes in each. So why should we say that, in meiosis 1, the chromosome number is reduced?
