Meiosis because each one is a part of your body but meiosis is a cell division process which is not a part of your body.
hematopoietic stem cells in long bones.
No part of the female reproductive system produces a sperm cell. Sperm is produced in the seminiferous tubules of the male testes.
Sperm cell of mammals has three parts which are the head, mid-piece, and the tail. The part that lashes for the sperm to move is the tail which is also called flagellum.
The nucleus of a sperm contains the DNA, seeing as a sperm is just another eukaryotic cell of the human body.
The tail.
Once a sperm fertilizes an egg, division begins to occur very rapidly so a mutation from either of those cells will affect any of the daughter cells. Sperm and egg cells are undifferentiated, meaning they are able to turn into any type of cell in the body. So a mutation in either the egg or sperm could potentially travel to every part of the body. Heart cells are differentiated (specialized) and are only able to divide into that type of cell, so a mutation in a heart cell will only stay in that area of the body.

The tail is the part of a sperm cell that is responsible for locomotion. Without a tail the sperm cell could not make it to the egg for fertilization.
