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 epidermis is the outermost layer of the skin. Categorized into five horizontal layers, the epidermis actually consists of anywhere between 50 cell layers (in thin areas) to 100 cell layers (in thick areas). The average epidermal thickness is 0.1 millimeters, which is about the thickness of one sheet of paper.
