Question

Norway rats have 42 chromosomes in their diploid cells. If such a cell enters meiosis, how many chromosomes and double-helical molecules of DNA will be present in each daughter cell at the end of meiosis II?
a. 21 chromosomes and 21 double-helical DNA molecules
b. 21 chromosomes and 42 double-helical DNA molecules
c. 42 chromosomes and 42 double-helical DNA molecules
d. 42 chromosomes and 84 double-helical DNA molecules

Accepted Answer

Hello everyone. And today we have a very short video. So let's jump straight into it. We have that. The deployed number of chromosomes in chimpanzees is 48 will be the number of chromosomes in the cell after Mayo's is too. And we need to do some math to solve this problem. But it's very simple. First of all, remember that deployed can be represented by to end. So the deployed number of chromosomes in the chimpanzees is 48. However, remember that this is deployed. However, my aosis use the general process relies on the creation of gametes And these gametes are Hap Lloyd because they must be mixed with other gametes in order to create a new organism. That is 48 chromosomes in total. So since these gametes are going to be Hap Lloyd, they're going to be represented by N. So we need to find this number. So let's make this calculation up here. We have that to n Equals 48. So and must be equal to 48 divided by two. And it's going to be equal to 24. So here we have the end or the hotline number in the cell after meals is two is 24 chromosomes. So it's going to be answer choice A and that will be the final answer to our problem. I really hope this video helped you and I have to see you on the next one
