The gal is real! As to the blue eyes, she had 'em. Contacts maybe?

 

Actually, the gene combinations could very easily result in a blue-eyed child of mixed race. Although brown is dominant, all it might take is for four blue-carrying alleles to attach to the proper chromosones. When we think of 1/2 thai and 1/2 farang, we usually think in terms of the mother either being Thai and the father farang. However, if the mother is 1/2 thai and 1/2 farang AND the father is the same, the child will be 1/2 and 1/2 and the chances for a blue-eye off-spring will (presumably) be much greater.

Years ago I knew a gal from Chiang Mai who had two Danish grandfathers. (King Rama V had a lot of Danes as officers in his police constabulary. He liked the Danes because they were no threat to the country.) She had brown hair and brown eyes. But her brother and sister had lighter hair, and I believe one of them had blue eyes. (Forget which one now.)

Cool. You are a fair bit further along than most professional geneticists!

 

Eye colour inheritance is *damn* complicated, and still very poorly understood. At least three genes (with a total of six possible alleles) are already known, and the dominance pattern is complicated. However, even that only gives an rough idea of the inheritance of blue, brown and green eyes. All the other combo's: Grey, hazel etc cannot be explained by the three gene model, so chances are there are several (?) other genes out there which also play a role....

What u say above is accurate from all that I've read. I must admit that my actual experience in genetic research has been limited to only 30 years of on-and-off testing in SEA. I've done my best to replicate my blue eyes with a damsel or two there (without success). Of course, the necessity to "cover up" for the past 10-15 years has somewhat hindered my experimentation :)

 

 

In reading the content of the url's you posted, I conclude that they support my contention...certainly do not contradict it. ::
