Write a 5 pages paper on coloration in reptiles. The production of color for the skin of reptiles is usually dependent on two sets of cells. chromatophores and melanocytes. However, the absence or presence of the cells and their distribution and density when present in each layer is the greatest determinant of coloration among reptiles. Melanocytes, which are usually present throughout the epidermis’ basal layers, are essential during the skin renewal process of epidermal growth since they send the pseudopodia into the keratocytes that bear the melanin. thus, initiating the transfer of the said melanin into the skin. In reptiles such as crocodiles, snakes and iguanids, the keratocytes are obtained in the β-layer while, in other reptiles, they may exist in both α and β layers. On the other hand, chromatophores are usually layered upon each other in the exterior portion of the dermis to provide the pigment cells xanthophores (yellow) and erythrophores (reddish-purple) plus other fat-soluble pigment cells for use in the construction of the basal membrane.
In this study, the main focus shall be on the understanding of the process of coloration among reptiles taking into consideration the evolution and genetics of variations in color among reptiles. The achievement of this shall be through the scientific review of about fifteen research articles conducted in various studies with the concept of coloration as the key theme. This broader coverage is to ensure adequate and in-depth analysis of the reptilian coloration. As such, the study shall be categorized into the genetically, evolutionary and morphologically impacts on coloration. The reviews shall mainly be from scientific papers written by different scholars under different themes but, centered on coloration.
