4 chromosomes, how?During Mitotic cell division, a parent cell with 4 chromosomes will produce 2 daughter cells each containing?
If you start with 4 chromosomes, DNA replication occurs so you now have 8 chromosomes in the cell, then mitosis steps occur and the 8 chromosomes get split into two separate cells, when you are all done you will have two cells each containing 4 chromosomes. There is no longer a parent cell.During Mitotic cell division, a parent cell with 4 chromosomes will produce 2 daughter cells each containing?

```please read whole thing, i am very confident u will understand when finished. if it seems like im not answering ur ? at first, that because im building up to it and filling in a picture that makes the concept much more comprehensible````
when a cell divides, it multiplies. in your case what your wondering is how a cell can halve itself n produce 2 complete cells...This happens because its not splitting during its normal metabolic phase.
If we resolve things deeper, and looks whats going on in the nucleus, u will be able to concentrate on whats going on in the nucleus (more specifically the genome) during this division phase aka mitosis.
Normally a cell is just doing whatever it is designed to do, say digesting in the stomach(at this point has 4 chromosomes). After some time the cell the will want to replicate. it may want to do this for many different reasons that i wont mention cuz im just trying to fill in the picture here. After the cell commits to this decision it will actually duplicate its dna(chromosomes) by a process known as replication. After replication is complete, the cell now has in its nucleus, 8 chromosomes. the cell will then grow much more in size.
when the cell finishes growing, it will now have enough mass (and chromosomes) to separate into 2 independent cells. This is the phase known as mitosis. during mitosis, the 8 chromosomes will be pulled apart to opposite ends, of this now huge cell body. after at opposite poles, the cell body will split down the middle, creating 2 new cells containing 4 chromosomes each.
sum up:ur not splitting it at its normal size. it doubles the chromosomes and doubles the size, then divides.
-in case math will have u c it better...1 divided by 2 is a half. n thats what is initially confusing u cuz u think they r saying 1 divided by 2= 2.
but what actually happening is, 1 is going to 2 and then it will be divided into 2, n 2 divided by 2 is 1. thus ul have two 1's. or, 1 doubled cell to 2 reg cellss
Because each chromosome replicates itself to prepare for mitosis. That way, the two new cells have all of the genetic info needed.
