During mitosis, the original cell produces two daughter cells. How many daughter cells will be produced if 250 mouse cells undergo mitosis?

There would be 500 daughter cells if 200 mouse cells went through the process of mitosis. (If that's what your asking)

Explanation:

During mitosis, the organism (which would be an asexual producer) doubles the amount of chromosomes and they divides the doubled number by two. So the organism will always end up with two daughter cells with the same number of chromosomes as itself. (That is the way with asexual producer's-their offspring is always an exact replica of the first). Now, if you take one mouse, it would end up with 2 daughter cells. If 250 mice reproduce, each with two daughter cells, then there would be 500 daughter cells in total, because you would multiply 2 by 250.  

it's unlikely a majority of a large population would agree on issues

hope this : )
