1. False. They are similar, though.
meiosis- A kind of cell division involving having the chromosome number. It is responsible for genetic recombination.
Gametogenesis- It's the process when gametes or germ cells are produced in an organism. They undergo meiosis to form gametes.
2. Spermatogenesis- happens in the testes of males. 4 gametes are produced. Spermatogenesis involves a metamorphosis stage called spermiogenesis. Spermatogenesis produces small, motile spermatozoa
Oogenesis- takes place in the ovary in a female. 1 gamete produced. in oogenesis there is no metamorphosis stage. In oogenesis the ovum is spherical, and isn't motile and is bigger with more food reserves and cytoplasm.
3. Because The one egg cell that results from meiosis contains most of the cytoplasm, nutrients, and organelles.

Explanation:
Answer:
Self-antigens are not recognized and attacked by the T cells.
Explanation:
In immunology, the antigens are those substances which are bound by the antibodies. The antigens can be originated from within the bodies, known as self antigens or from outside the body, known as non-self antigens. The immune system identifies and attacks non-self invaders or the foreign harmful objects present in the body. It does not attack the self-antigens under the normal conditions. This is due to the negative selection of T cells of the thymus.
