Many genes govern the development of eyes, and different populations of cavefish have lost their vision by disrupting
different eye genes.

How can a parent with one
eye color have
genes for a
different eye color?
The survey, described today in a Policy Forum published by Science, randomly presented people with
different vignettes that described genome editing being used in germline or somatic cells to either treat disease or enhance a human with, say, a
gene linked to higher IQ or
eye color.
They used the same basic tool kit to build their
eyes but the precise details of the
genes are slightly
different.
Much of the recent research into
eye development has focused on the cascade of
genes that turn on at
different times to coordinate the process, but researchers thought electricity didn't play a role.
Twenty years after he first stumbled on FOP, Economides and his colleagues report today that the
gene mutation shared by 97 % of people with the disease can trigger its symptoms in a manner
different than had been assumed — through a single molecule not previously
eyed as a suspect.
Other possible symptoms of the disease, which is usually caused by
different mutations of the JAGGED1
gene, are deformities of the
eyes or bones, and sometimes growth disorders.
Mature miR - 7 is individually transcribed and processed from 3
different gene locus in human genome, and it is highly expressed in parts of the brain,
eye, and pancreas, suggesting its role in the development of these organs (20 — 22).
By comparison, only two of the 15
genes were not significantly
different when comparing the
eye field to PNP or LE data sets (Table S1).
And then on top of that, of course, you have this cell - specific program with these master - regulator
genes that are making a blood cell
different from an
eye cell
different from a skin cell.
Recent genetic association studies identified variants in a locus on chromosome 15 (specifically, in the adjacent
genes HERC2 and OCA2) that are major determinants of
eye color, but the trait is influenced by interaction among at least ten
different genes.
(Incidentally, Huskies don't have blue
eyes because they carry the Merle
gene, but because they carry a
different gene which causes blue
eyes independently of coat color.)
There is a known link between white coat color, blue
eyes and deafness - but since the coat and
eye color can be caused by
different genes it means that only some blue
eyed whites are deaf.
This breed also carries the
gene for heterochromatic
eyes, in other words,
eyes of
different colors.
However, one word of caution to be aware of is that since both parent breeds carry the
gene for heterochromatic (
different color)
eyes, they are prone to
eye problems like glaucoma and cataracts.
