The phrase
"pigment genes" refers to the specific genes responsible for determining the color or pigment in an organism's skin, hair, or eyes.

The team discovered that
visual pigment genes have changed substantially during snake evolution, including many changes to the wavelengths of light that the pigments are sensitive to.
Neitz's new work rests on a detailed molecular analysis
of pigment genes that encode proteins responsible for the eye's sensitivity to various wavelengths of visible light.
The next step, he said, is to demonstrate the same results among those called protananamolous, who suffer from a less common form of color blindness involving an overabundance of
red pigment genes.
The genes that affect hair colour also affect other cancer types, while
other pigment genes affect the chances of having Crohn's and other forms of bowel disease.
Researchers analyzed the genomes of 16 related orange and white tigers in captivity, fully mapping those of the three parent tigers to show that a mutation in one
pigment gene called SLC45A2 is at play — the very same gene that drives lighter coloring in people of European ancestry, chickens, and some mice.
«Evolutionary shifts from blue to red flowers in Penstemon predictably involves degeneration of the same particular
flower pigment gene, suggesting there are limited genetic «options» for evolving red flowers in this group,» said Wessinger.
Now, researchers have discovered how the corals»
pigment genes control the range of colors they can produce.
Florigene researchers had to splice a gene that produces the blue pigment delphinidin into rose DNA and also turn off the rose's natural
red pigment gene.
Many of these genes lie within the DNA segment that differs between carrion and hooded crows, suggesting that somehow
the pigment genes that give the two groups their unique appearance are also keeping the species separate.
Reasoning that the female version of L - opsin might also do the trick for males, researchers from the University of Washington used a harmless virus to carry
the pigment gene behind the monkeys» retinas.
The more copies of
the pigment gene a coral has, the brighter its range of potential colors.
At a very early stage, I introduced
the pigmented genes into the white embryos with a syringe.
So what they did was they put into E. coli genes for pigment to turn it dark and they essentially linked up
these pigment genes with light sensing genes, and so if you exposed a big plate of E. coli to a picture on your bright light, it would make its own picture.
Using a harmless virus, the scientists introduced
the pigment gene into the eyes of color - blind adults.
Pigment genes could affect the chances of having Crohn's or other bowel diseases.
Genetic transmission of deafness in dogs with the recessive alleles of
this pigment gene, such as the Dalmatian (which is homozygous for sw), is less clear.
