Alrighty, where to start... I feel like I have so many questions but it's probably just a few. Welp, my first question about genetics: If someone has a heterochromic eye, would they be a chimera and therefore have Blaschko's lines? 2nd Q: Do all chimeras have Blaschko's lines? I realize that some chimeras do have similar skin tones with both sets of DNA but you could still see the difference with a black light. 3rd Q: Hazel eyes... If Brown eyes have only slightly but noticeably green (only in a certain lighting) on the edges, they are considered Hazel then, right? Even though they are mostly brown? That seems to be all of my Q's in a nutshell. x3 Thanks for reading and I hope to read your replys soon. :3 Edit: Corrected Typing Errors
