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

could blue eyes be dominate over brown?

Accepted Answer

Generally not: Brown eyes dominate over blue.  While eye color inheritance is somewhat mixed, if the only colors in question are strongly blue and strongly brown, then brown dominates.  This means of the two genes for any one characteristic, in this case brown, if you have one brown (the other can be either), your eyes will be brown.  You would require two blue genes to get blue eyes.

Accepted Answer

Question 7

Question 8

Accepted Answer
