I know what the "acceptable" eye colours are, according to breed characteristics, and have gathered from reading various topics here that the "forever" colour is determined at about 6 months . . .

But my question is, do there appear to be any trends as far as the instance of blue vs. white (gray) vs. amber? Any difference between the silvers and the blues in this department? Any difference between the sexes? If I were to guess, it seems that the boys are more likely to keep their blue (or more blue-ish) eyes than the girls; but this is solely based on my own observations.

Is there any rhyme or reason to it?

Look to the parents to see what you might expect from the offspring. it doesn't have anything to do with gender and my observation is that it might be tied to the degree of dilution of coat color (regardless of gray or blue) but that also tends to be inherited too.

Interesting. Is any one parent's genes more dominant than the other in that department?

I just find the eye colour question really interesting. In dogs as much as in people.

I don't think anyone really knows the inheritance of the degree of darkness of the amber eyes... I'd guess that its a penetrance issue, not a pure dominant/recessive deal.

from our observations here... just to add my two cents... zoe is much darker in color, much more amber to her coat, and her eyes are amber. riley has the crazy markings and a much lighter coat (although I imagine it will continue to darken yet with time) and her eyes match - they are lighter, almost gray - close to the full moon color.
guess we could take an informal straw poll here to see what others have noticed.

That's an idea.

The issue has always intrigued me, starting with my own eyes. My eyes are blue, but genetically speaking, people have often told me it's odd that I would end up with them, given my parents and extended family's dominant eye colour.

Mailman? Top secret adoption? Laughing

In humans, brown is dominant over blue, so if your parents have brown eyes, they were both carrying the recessive blue gene, which was "hidden" by the domant brown gene.
That's the simple explanation only considering one allele and the difference between brown and blue only.
There's a different allele involved with green eyes, and brown is dominant over green, but green is domiant over blue.

im having flashbacks to my college days.
genetics is fun isnt it.
the fact that you have blue isnt crazy, its just a matter of statistics.
odds were against you that two recessives would have been expressed to give you the blue.

I read in an article recently that blue eyes in humans was originally a genetic mutation, and that every single person in the world who has blue eyes is actully a descendant of the one human who originally had them.

I don't know much about genetics - I don't know if that's crazy far-fetched or plausible.

If so, I've dated a lot of guys who I'm "related" to. Shocked LOL

So you live in Texas too?=) hehe....I swear...my family is all over and pretty "broken" I have a dad who had more kids that I don't know...so I was always like " so umm...who's your daddy?" haha

On the doggy note...I am pretty sure that Wrench is related to an Elephant....in fact we have decided upon his holloween costume already ( god I am a crazy mom)

I've always thought Marley's coat was a little dark, but her eyes turned out very light. She definitely has the 'ghost' look at night.


On a side note, I have red hair and no one in my family does. It could be recessive or a mutation of that particular gene.
