Thinking about the eye color, why is it so unreliable.
If the information is verified by Parabon, I understand how it can be so unclear.
My eye color is grey-blue. No one would mistake it for brown.
Yet all ancestry sites give me "brown". They are not totally off.
The chance of having "blue" eyes with my genotype, they say, is only 5%, so they "go" with more probable version.
So what I probably got (and
What happens IRL?
My dad has sky-blue eyes, recessive genes on both sides.
On my mom's side, her mom had blue-grey eyes, her dad, light-brown (dominant). Mom had a mix (green), this often happens in such cases (it is probably blue-grey with specks of brown that creates this intense green color); her brother has light-brown eyes. Both would have been assigned "brown" by genetic tests.it is what the companies see) is the gene for brown eyes, but in my specific case, the "mix" from mom's and dad's sides produces grey-blue color.
In reality, it is even more complicated,; last time I checked, there were 12 genes coding for eye color, one cancelling the other one. Maybe there are more now, but the companies go with more probable version.
So truly, if the perp's father has brown eyes, and mom, blue, he might have something between grey and green eyes, and in different light, the color might look different. So witnesses might give different colors. Or, like me, he has grey, but the Parabon probably will say, brown, as the chance of "brown" will be much higher, statistically. However, IRL, like myself, he might fall into 5% that is grey.
The genetic companies will "read" your DNA. There are epigenetic factors (something affecting the looks after you were born) that might change the look, and dramatically so.
ETA. Thinking again - blue eyes of the perp. would be more likely if the brown-eyed parent would have a parent with blue eyes, and a parent with brown ones. If brown-eyed parent had two brown-eyed parents, the chance of the perp to have brown, or green, eyes would be higher. I might be wrong from the genetic side, but so it seems so from the observations. Beautiful green eyes may be perceived very differently in different lights, but they are a combo of light brown and blue.
