Nastasia [14]
I presume your question is, how many chromosomes would be found in the resulting daughter cells of meiosis?

If parent cell has 16 chromosomes, the first division in Meiosis of the cell will result in 8 chromosomes, and the second division (I.e. the separation of the sister chromatids of the 8 chromosomes) results in 8 daughter chromosomes.

The number of chromosomes in each cell resulting from meiosis is 8.

Hope this helps! :)

URGENT!!!!!!!!!!!!Which are examples of convection currents? Check all that apply.
Aloiza [94]
I believe a pot of water that is being heated by a electric burner. This is because the warmer water moves to the top and the cooler water moves down to the bottom of the pot. This causes a circular motion. The next example of convection heat is a hot air ballon rising and falling in the atmosphere. A radiator is also because the hot air is drawn out the top and the cooler air is drawn to the bottom.
