This is known as heterochromia - and is caused by differing amounts of a pigment called melanin. This can have a genetic cause or be the result of disease or illness.

When the irises are two different colours, this is complete heterochromia.

What are all the possible eye colors of a human?

Common eye colors in humans include brown, blue, green, and hazel. Less common colors include gray, amber, and violet. Eye color is determined by genetics and can vary based on the amount and type of pigmentation in the iris.


What eye colors are dominant and which are recessive?

Brown eye color is dominant, while blue, green, and hazel eye colors are recessive. This means that brown eyes are more likely to be expressed if an individual inherits one brown-eyed allele and one allele for a different eye color.


Why can a person with brown eyes carry blue eye alleles but a person with blue eyes cannot have a brown eye allele in their genotype?

A person with brown eyes can carry the blue eye allele because brown is a dominant trait, so they can have both blue and brown alleles in their genotype. However, a person with blue eyes cannot have a brown eye allele because blue eyes are a recessive trait, meaning they must have two copies of the blue allele in their genotype to express the trait.


Are blue eyes more dominant than brown eyes?

No, brown eyes are more dominant than blue eyes genetically. Brown eye color is a dominant trait, while blue eye color is a recessive trait. This means that if a person has one gene for blue eyes and one gene for brown eyes, the brown eye gene will be expressed.


What eye color do you mix with brown and blue?

When mixing brown and blue eye colors, you can expect to see a combination of green or hazel eyes, as these colors often result from a blending of brown and blue pigments. The exact eye color may vary depending on the specific shades of brown and blue present in the individual's genetic makeup.

Why Several genes control human eye color. Because of this eye color shows a continuous variation from very dark brown to green to blue. What is this an example of?

Eye color is not an example of polygenetic traits. Skin color is. Eye color is rather simple as far as genetics go (in humans). Brown (B) is dominate and blue (b) is recessive. A person with blue eyes has to have to have both genes for the color blue (bb). A person with brown eye color can has both genes for brown (BB) or one for brown and one for blue (Bb). The blue is not expressed in this case with Bb. Some people have hazel eyes but this is a variation of the blue color.

What do you think the possible alleles for eye color in humans?

The possible alleles for eye color in humans are typically variations of the genes that control the production of melanin, such as the OCA2 and HERC2 genes. Common alleles include those for brown, blue, green, and hazel eyes. The combination of these alleles contributes to the wide range of eye colors observed in the human population.
