Genetically. They are genetically alike both to each other and to the parent cell. Mitosis: duplicates the number of chromosomes ------- divides the nucleus ------ then divides the cell into two new cells each having the same number of chromosomes (and of course genetic makeup) as the parent cell had. <= [notice the word "had"]. The parent cell is no longer there after mitosis. Example: If a cell had 23 two pairs of chromosomes [[i.e 46 chromosomes total]].... It duplicates them to have 46 two pairs of chromosomes... 23 two pairs move to one of the new cells and the remaining 23 two pairs move to the other. Now we say they are alike in having 23 two pairs each and in that those pairs are copies of each other and therefore are composed of the same DNA sequences (at least theoretically).
