The purple eye coloration is caused by a mutation in the anthocyanin biosynthetic pathway. Anthocyanins are pigments responsible for the colors of many fruits and vegetables. In the case of cannabis, they produce a deep purple hue in the flowers. Purple eyes have been observed in both Indica and Sativa strains, although indicas tend to be more heavily affected than sativas.
Purple Eyes overview
These genes encode enzymes involved in the synthesis of the pigment anthocyanin. Mutations in these genes result in the production of non-functional forms of the enzyme. When this happens, the flower does not produce any anthocyanin, resulting in a white-colored bud.
PEP1 (also called ANS) encodes an enzyme that catalyzes the first step in the synthesis of anthocyanin. The gene is located on chromosome 1 and contains two exons and one intron. This variant causes a change in codon usage at position 644, changing the encoded amino acid from leucine to proline. This results in a loss of function since the mutated protein cannot properly fold.
PEP2 (also called UFGT) encodes an enzyme involved in glycosylating anthocyanidins. The gene is located in chromosome 5 and consists of five exons and four introns. There are no SNPs associated with PEP2. However, there is one report of a deletion causing a frameshift mutation. This mutation would likely lead to a stop codon before the second exon, resulting in a truncated protein.
PEP3 (also called F3H) encodes an enzyme necessary for the conversion of flavanones to dihydroflavonols. The gene is located near the end of chromosome 9 and contains six exons and five introns.

Violet eyes
While rare, crimson or violet eyes can certainly occur, because of a mutation, irritation in the eye, or a circumstance known as albinism. While rare, crimson or violet eyes can certainly occur, because of a mutation, irritation in the eye, or a circumstance known as albinism
Alexandria genesis
Alexandria`s Genesis is a web fable approximately best people whose eyes flip crimson at some point of infancy. According to Snopes, a famous fact-checking site, rumors approximately this so-known as uncommon genetic mutation were circulating the net due to the fact that as a minimum as a long way returned as 2005. Learn a way to spot faux fitness stories.
The fable of Alexandria`s Genesis, which has numerous peculiar foundation stories, claims that human beings with this situation are born with crimson eyes or have eyes that flip crimson rapidly after birth. They additionally have faded pores and skin and nicely proportioned bodies that don`t benefit from weight. These best people supposedly stay to be nicely over a hundred years antique and bring little or no physical waste.
Alexandria`s Genesis isn’t always an actual clinical situation. But there are numerous actual-lifestyles situations that can have an effect on eye color. Read directly to research greater approximately those situations.
How rare are purple eyes
I was wondering if anyone else noticed this? I have never seen any kind of seed seller offer purple seeds or even think about them. Not only do they not sell them, but they don’t even know how to breed them. Even though I’ve heard of purple eyes being rare in some strains, I never expected them in my own personal favorite strain, Blueberry.
I’ve been breeding for two years now and have never seen anything remotely close to blueberry in my crosses. So what’s going on? Is there something wrong with the genetics of these purple-eyed plants? Are they just extremely rare? Or is it possible the breeder who sold me the Blueberry plant might have crossed his Purple Eyes onto the original Blueberry plant.
The only thing I can think of is that you may have accidentally bred half-blueberry/half-purple eyes.
Purple eyes are pretty rare in nature. In fact, they seem to be almost exclusively associated with mutations in the anthocyanin biosynthetic pathway (the enzyme responsible for producing the color).
Most likely, your breeder simply doesn’t know about the trait, or thinks it’s less useful than other traits.
What are the eye color chart?
The eye color chart below shows the percentage of each pigment (color) that makes up the eyes’ iris, pupil, and sclera (white).
Black people have around 50% black pigments in their eyes.
Brown-eyed people have about 40% brown and 20% blue pigments in their eyes while hazel-eyed people have about 60% brown, 10% green, and 30% blue.
Red-eyed people have less than 20% red pigments in their eyes, while blue-eyed people have over 80%.
Green-eyed people have about 65% green pigments in their eyes and 25% yellow pigments.
Blue-eyed people have almost 90% blue pigments in their eyes.
Gray-eyed people have between 45% and 55% gray pigments in their eyes; they have lighter colored eyes than green-eyed people. Blue-gray-eyed people have about 70% blue, 15% gray, and 5% brown pigments.
White-eyed people have more than 95% white pigments in their eyes
This is not an official chart. There are many variations depending on what type of eye makeup someone wears.
Natural purple eyes is a natural color that comes from the plant world. It is a beautiful, vibrant color that is rich in antioxidants. Purple-eyed strains are often indica-dominant hybrids, meaning they have high levels of THC and low CBD amounts. The most popular purple-eyed strain is Sour Diesel, a Sativa/Indica hybrid strain that has been around since the early 1990s. To get that amazing color, look for a bud that’s dense and heavy, with lots of trichomes covering the surface.
Are purple eyes real?
- Yes! Purple eyes are caused by a pigment called bilirubin, which comes from broken down red blood cells.
- No! Purple eyes aren’t contagious at all, they’re just a natural coloration of some people’s irises.
- Yes! If you have a low-iron diet, then you may develop iron deficiency, which causes you to turn blue. However, if you don’t get enough vitamin C, then your body will not produce enough hemoglobin (which carries oxygen throughout our bodies) to make your skin appear bluish.
- No! Your eyes won’t actually change color unless you have a condition called jaundice. Jaundice occurs when the liver doesn’t properly digest certain chemicals. People who have jaundice tend to look yellowish due to their increased levels of bilirubin.
- Yes! When your body is exposed to high temperatures, it produces extra sweat glands to cool off and release excess toxins. These toxins can cause darkening of the skin, especially around the eyes.
Is it possible to have purple eyes?
Purple eye coloration isn’t just a myth. In fact, some people actually do have naturally occurring purple irises. However, it’s not something you might want to focus on if you’re looking to improve your attractiveness.
You may know that there are different types of eye colors, including blue, green, hazel, brown, gray, and even black. But did you know that there are also a few rarer types? One of these is called purple eye coloration. So what exactly does that mean? Well, it means that there is a small amount of pigment present in the iris, resulting in a slightly bluish tint that gives off a purple hue.
Final thoughts
But why would someone get naturally occurring purple eyes? There are several reasons. First of all, it could be due to genetics. If a person was born with a genetic mutation, then they could inherit the trait from their parents. Another possibility is that eye coloration came about after birth. Perhaps the baby had an illness that caused them to lose a lot of fluid, which resulted in swelling in the eye area. As this happened, the blood vessels around the iris became dilated and the natural hue turned purple.
