In genetics, eye colours (brown, green and blue) are determined by bey2 and gey genes. But what about hazel, grey and amber and more? I read a webpage about hazel eye colour and saw that there is a 3rd gene called 'hey' with 'codes' H and h Other than B(brown), G(green) and b(blue) but now what does H and h mean when there is one hazel?

  • $\begingroup$ Welcome to Biology StackExchange! According to the guidelines of this site, your question might seem a little bit under-researched. You should also provide references to your statements. For example: "eye colours are determined by bey2 and gey genes" is not an accurate statement because (as you can read on Wikipedia) "The genetics and inheritance of eye color in humans is complicated" and "So far, as many as 15 genes have been associated with eye color inheritance". $\endgroup$

    $\begingroup$ Therefore, I suggest you read some more (online) resources on this topic, and then try to edit your question into a more detailed and focused one, along with the references you have read :-) There are also some useful answers on this StackExchange, such as Why are human eye colours limited? and How is eye color in humans inherited?. $\endgroup$
