Question 1

how to end up with blue eyes if brown are the dominant genes?

Accepted Answer

Brown is dominant: Both parents are heterozygous with one allele for brown leading to a phenotype of brown eyes. There is a 25% chance to pass on the non brown gene to offspring.

Question 2

can you tell me in human beings, brown eyes are usually dominant over blue eyes. suppose a brown-eyed woman whose father had b?

Accepted Answer

Eye color: is genetically complex with a number of factors that determine the actual color appearance.  However the brown gene is dominant and the blue gene is recessive.  Since only one dominant gene is required for brown eyes, then brown eyed parents can produce blue or brown eyed children, while two blue eyed parents should produce only blue-eyed children.

Question 3

sister has brown eyes, other two siblings have blue eyes. what gene is dominent?

Accepted Answer

Brown over blur: The inheritance of eye color is somewhat complex but when it comes to brown v. blue --- brown is dominant over blue.  In your family, Mom and Dad probably have brown eyes but carry one gene for brown and one for blue.  There is a 25% chance of a child in this mix with blur eyes.  All other combinations will be brown.  It is a matter of statistics.

Question 4

can you make brown eyes blue, somehow?

Accepted Answer

No: Eye color is established at a very young age and only slightly changes as the iris pigmentation slightly atrophies. Certain eye medication for Glaucoma can affect eye color. The most common method is using colored contact lenses to temporarily change the iris appearance. If you're motivated to try contacts, make an appointment to see a eye doctor who can fit them to your eyes.

Question 5

blue ring around dark brown eyes a vision problem?

Accepted Answer

Probably not: This is most likely a deposit of lipid term 'corneal arcus'.  It is benign and will not affect the vision.  If the eye is red, painful, or the vision is changing rapidly, - there are some pathologic changes that can occur in this part of the cornea which will appear like a blue ring.  These are rare but will need an ophthalmologist to look at them.

Question 6

why do i have a blue ring around my dark brown eyes?

Accepted Answer

Ring around eye: this is probably an Arcus. It appears to surround the colored part of the eye.It's actually in the cornea.It is usually gray color,but may appear bluish.It is perfectly benign. In a younger person it is a good idea to have a cholesterol test,since it is fatty degeneration.Sometimes it is familial.It does not effect vision or cause any ocular problems.

Question 7

how come all my family have brown eyes when i have blue?

Accepted Answer

Recessive gene: Brown eyes are a dominant gene.  It is much more common.  It does not mean that you are not related to your family.

Question 8

is it weird to have brown eyes with a blue ring around it?

Accepted Answer

No: The bluish ring is usually a intra corneal cholesterol deposit known as arcus senilis. It may indicate an increased cholesterol and your doctor should check that. The other ring that is rarely seen is a kaiser-flescher ring seen if patients with a problem with copper metabolism (wilson's disease).

Question 9

i have brown eyes but there is a blue ring around it is this normal?

Accepted Answer

?corneal arcus: If you are referring to the "blue ring" around the peripheral cornea, this is called corneal arcus--represents cholesterol deposition from the limbal blood vessels that normally appears in people over 40. More often visible in brown colored irises due to darker background. If you are younger than 40 and are noticing arcus, an examination by an Eye MD to verify &amp; check lipid profile important.

Question 10

what could cause a blue halo to form around my once dark brown eyes?

Accepted Answer

See below: Sounds like you may have arcus senilis (cholesterol deposits in the outer circumference of the cornea). You are a bit young for this though. See your eye doctor and get your cholesterol checked.
