It seems that there are still genes involved that have yet to be discovered. I assume that no family members related to the Asian mother have green or blue eyes which could indicate that she might be a recessive carrier. Still, the scenario is still possible based on what I read from this response from Dr. Barry Starr, a geneticist at Stanford Univ: http://www.thetech.org/genetics/ask.php?id=2 Iris stromal melanocyte density was found to be similar in Caucasians with blue, green or hazel colored irides, but was found to be significantly lower in Asians even with dark brown irides (Albert DM et al 2003). The contribution of these racial-ethnic differences in melanocyte density may play some indirect role in the iris appearance of Hapa.
