There are many organisms (mainly protozoans) in which the nuclear membrane remains intact during mitosis. The chromosomes separate within the nucleus and then the nuclear membrane pinches off, to form two nuclei which migrate to the two poles.
The reason that this is seldom mentioned is that textbooks usually only describe the most common examples of processes due to space limitations

How would the doubled genetic material get to the daughter cell if all was locked in a unbroken nuclear membrane.

it relatively is been awhile as a results of fact I took bio, yet i understand that mitosis is the branch of cells, and meiosis is the branch of intercourse cells. i do no longer bear in mind lots extra advantageous than that, sorry =(

The cell would not divide in to two cells. You would be left with one cell, with chromosome number of 4n - twice the number of chromosomes in a normal cell (which is 2n).
Most animal cells cannot survive such a drastic chromosome number increase, but there are many plants that can be shown to actually be a 4n arrangement of an ancestral 2n plant.

the process of mitosis would go on without the chromosomes and it would make a daughter cell with no chromosomes and then the daughter cell and the other cell would die off
