I have got information on how eye colour is determined. There it is suggested that eye colour is determined by eight genes where each gene is either for or against storage of a pigment named melanine in the outer iris of the eyes, and hence, there are nine eye colour tones. A little melanine gives blue eyes, a little more melanine gives green eyes and lots of melanine gives brown eyes. If you believe that this is wrong, please tell me what you believe is correct.
Now, I am wondering if there is anyone in here who can tell me how hair colour is determined and inheritated. I have read that it's inheritance is very complex. Any suggestions?
