The dog genome is basically the human genome divided into about 70 different pieces and rearranged on a greater number of chromosomes, according to a new map of the dog genome.While making the map, the researchers lined up each chromosome segment in the dog with its corresponding region of the human genome.he dog genome is basically the human genome divided into about 70 different pieces and rearranged on a greater number of chromosomes, according to a new map of the dog genome.
There are three main layers if skin but there are layers within two of these layers. One of these layers is the epidermis; the epidermis is the top external layer and has five layers within that layer.
The skin is the largest organ in the human body. For the average adult human, the skin has a surface area of between 1.5-2.0 square metres (16.1-21.5 sq ft.), most of it between 2â3 mm (0.10 inch) thick.The average square inch (6.5 cmÂ²) of skin holds 650 sweat glands, 20 blood vessels, 60,000 melanocytes, and more than 1,000 nerve endings.uman skin is similar to that of most other mammals, except that it is not protected by a fur.
