Type towards prices away from the color loss of sight for the guys
The fresh new L (OPN1LW) and you may M (OPN1MW) opsins are located after this new long arm from brand new X-chromosome (Xq28). These types of much the same family genes changed out-of duplications of just one gene and you will next mutations and get across-more situations starting crossbreed family genes to help you a variety of genes, for each and every with assorted level spectral susceptibility. Certainly those with typical the color vision, discover variability on the number otherwise homology away from pictures-pigment family genes and their arrangement from inside the a combination selection allows for a premier mutation rates (Fig. 15).
