    Hi I have a question. I’m confused when you explained at 2:30 how the cell at the start has 8 chromosomes then your dived into to cells. Each cell will get 4 and then you divide again. Shouldn’t then each cell get 2. I don’t understand how it’s still 4. Even in the diagram the there are 4 chromosomes in the first picture and 8 chromatids. Then in but the end each cell has 2 chromosomes
