The body's immune system thinks what he/she is eating or inhaling is a pathogen. The immune system sends white blood cells to attack. This triggers an allergic reaction.
For example: I am allergic to asparagus (I'm not joking, I really am) and walnuts. Anytime I eat one of those, my body's immune system thinks it's a pathogen for some reason and attacks and triggers an allergic reaction in me. This makes my breathing hard and makes it really itchy. Good thing it's not that severe so I can eat some if I want, but sometimes allergic reactions could cause hospitalization or death.

During spermatogenesis, some diploid spermatogonia become larger in size and transform into primary spermatocytes. These diploid primary spermatocytes enter meiosis to produce haploid spermatids. One primary spermatocyte enters meiosis-I and produces two secondary spermatocytes. These secondary spermatocytes are haploids. Each of these two secondary spermatocytes enters the meiosis-II and produces two haploid spermatids. In this way, one diploid primary spermatocyte produces four haploid spermatids.
