Hello everyone. And in today's video we have the following problem. In order to create gametes a blank must go through the same number of blank in both human men and females. And so in order to solve this problem let us quickly just lend over answer choices to see what can see these first blank that we have here. So it can either be germ cells, stem cells or somatic cells. Now somatic cells are just regular cells in the body that don't really just create gametes. So we're going to cancel our option D because of that. Moving on we have stem cells and these stem cells are going to be just undifferentiated type of cells usually present in the fittest of the humans. Which are not going to directly create gametes. These gametes are created from another type of cells which in this case are going to be germ cells. So now in order to pick between A. N. C. Let me quickly remind you how gametes are created. Well as we said every gamma comes from a germ cell. However this germ cell is going to be able to perform one of two processes in order to divide. It is either going to divide by mitosis were a similar or just an equal cell will be created after the division. So mitosis will result in a germ cell or it can divide by may aosis which is going to create what we see here which is a gamut. So a germ cell. So in order to create gametes age cell must go through the same number of biotic cell divisions in both human males and females as that's the way that gametes are created, which makes options see the correct answer choice. So thank you very much for watching until the end of this video, and I really hope I helped you.
