That's the number of complete sets of chromosomes the gamete contains. Typical human cells are diploid, meaning 2n, meaning they have one complete set from their mother and one complete set from their father. An ovum is haploid, meaning just n.

When a sperm comes in contact with an egg, the sperm releases enzymes to help it penetrate the egg's outer layer.

How does a human reproduce?
Every 28 or so days a female matures and releases an egg cell. The male can produce sperm cells. During human intercourse (coitus or mating) the sperm cells will reach the egg and only one sperm cell will fuse and enter into the egg for fertilization. The DNA of egg and sperm cells (n+n) unite together to form a zygote (2n) which will be then implanted in the lining of the uterus for embryogenesis (formation of a fetus or baby from single fused cell).

Why does the egg's covering change after a sperm has entered the egg?
The change in the egg's covering is due to a process called the zona reaction, which is triggered by the entry of the sperm into the egg. This reaction helps prevent other sperm from entering the egg, ensuring that only one sperm fertilizes the egg.
