Answer:
To understand the tanning process one first needs to realize that the skin is comprised of several different types of cells. Each type of cell has a specific function. The cells involved primarily in the tanning process are called melanocytes. Melanocytes are located at the base of the epidermis between the epidermis and the dermis below. Melanocytes use the amino acid tyrosine to produce melanin. This melanin leaves the melanocytes and travels up through the epidermis where it reacts with the UVA and UVB radiation through a chemical reaction darkening the pigmentation of the skin. As we already know the skin consists of three layers of tissue: The epidermis or outer layer, the dermis or inner layer and the subcutaneous layer

A typical human karyotype has 23 types of chromosomes arranged from largest to smallest. In males and females 22 of these chromosomes look exactly the same and they are called autosomes. The 23rd pair of chromosomes is the sex chromosome which differentiates males from females. Females have 2 copies of the x chromosome. Males have a copy of both x and y chromosome to make the 23rd pair. <span>
<span>Chromosomes can also have abnormalities that result to different conditions and identifiable traits. A most common chromosomal abnormality is the condition called Down Syndrome, where chromosome 21 has a third copy because of an abnormal cell division.</span></span>
