A common biological study specimen, the fruit fly, has four pairs of chromosomes in each cell. As it grows, it reproduces more cells via mitosis. How many chromosomes would you expect to find in each new cell?

Each new cell will have four chromosomes

Explanation:

In mitotic cell division, one cell divides to produce two identical cells with exactly the same amount of genetic amount i.e chromosome as that of the parent cell.  

In this case the total numbers of chromosomes in parent cells are four which means each new cell will have four chromosome i.e exact amount of genetic material.  

your answer is rna to the question.

ya the other dude is right
