Hey, if a person had an immune system consisting of only Th1, Th2, NK-cells, DC and B cells, which type of pathogens would not be cleared/would be fatal? Thank you very much.

Hello, Gene for cataract is located on X chromosome. This disease is gonosomally recessive. Let's say two healthy parents have twins (both males - sons). I am supposed to decide whether those twins are monozygotic or dizygotic if: A) both sons have cataract; B) one son is healthy, the other one has cataract; C) both sons are healthy Also could you decide in this case about twins being monozygotic/dizygotic if they were females? Thank you for your help
