It is called the Epidermis. The epidermis, the outermost layer of skin, provides a waterproof barrier and creates our skin tone. The dermis, beneath the epidermis, contains tough connective tissue, hair follicles, and sweat glands.
A gamete is a haploid cell, a cell with only one pair of chromosomes. Say the skin cell of a human has 46 chromosomes (2 pairs), a gamete would have 23 chromosomes (1 pair) because gametes are sex cells. When a sex cell (Egg and sperm) come together, they together will create a dipole cell (46 chromosomes, 2 pairs).
