Question

Assume that you were examining a first polar body and noted that it had one copy (dyad) of each chromosome except chromosome 21. Chromosome 21 was completely absent. What would you expect to be the chromosome 21 complement (only with respect to chromosome 21) in the secondary oocyte? What consequences are likely in the resulting zygote if the secondary oocyte was fertilized?

Accepted Answer

Hello everyone and welcome to today's video. So during my aosis of O genesis, a cell that contains a nucleus separates from the outside. The cell is a non functioning egg that usually cannot be fertilized. The cell is referred to as well. Let's visualize this process of genesis so that we can get a better idea of what's going on here. We have this primordial germ cells that are going to divide via mitosis to form the algo nia. These oregonians are going to keep dividing to form all sides, which is where the question really starts here, we have it. Now this all sides can produce either polar bodies or the actual album. Now the album is going to be fertilized. On the other hand, these polar bodies are going to be these cells that separate from the outside that have a nucleus will have very little cytoplasm and their faith is used to undergo apoptosis and basically be eliminated. They're never going to be fertilized at least not enough in the general set of things. Because of this the cell which is a non functioning egg that cannot be fertilized is referred to as a polar body. Because of this. The correct answer choice is going to be answer choice. C I really hope this video helped you and I hope to see you on the next one
