If father and mother both have blue eyes is it possible to have a baby with brown eyes?

Answer 1

There is a chance the baby will have blue eyes but only 1:3 chance.

You carry 2 blue eye genes.

If he carry's 2 brown genes then all your baby's will have brown eyes.

But, if he carry's 1 brown gene and 1 blue gene then the chances of blue:brown eyes are 1:3.

Hope this helps :)

Answer 2

More than likely blue at first then changing to a brown or browny-blue. Most babies start off with blue eyes, but blue is a recessive however brown is a dominent gene.

A baby's eyes are first blue because they have not developed fully yet. they then change color or stay the same after three months. it is more likely that the baby would have brown eyes. it also depends on your parents eyes and his parents eyes. if most of them have brow. the baby would most likely have brown eyes.

Answer 3

Yes, your child will most likely inherent the allele that causes blue eyes from both parents, thus causing blue eyes to be evident.

Second Answer: most likely your child will have blue eyes, considering both half of there genes are blue eyes. Although not always will your child have blue eyes. There may be a family member down the line, maybe of many ancestors that will dominate the eye's color. My aunt and uncle both have brown eyes. They had four children. Three of the children had brown eyes while the last child had bright blue eyes because it was passed down from many generations. But most likely your child will have blue eyes.

Third answer: Yes, your child will almost certainly have blue eyes. A quick lesson in genetics: for every possible trait, you have two different versions of a gene, called alleles. One copy of the gene is from your mother, the other is from your father. One version of a gene (again, called an allele) is dominant, one is recessive. If you have a dominant allele passed on to you, that trait will always show up, even if the other allele is recessive. You need two copies of the recessive allele in order for that trait to show up. Here are some examples of dominant and recessive traits (keep in mind some traits are controlled by multiple genes, and sometimes rather than getting one trait you get a mix - such as a dark-skinned person and a light-skinned person having a baby with medium-skin, but this is a basic breakdown).

Hair color:

brown and black: dominant

blonde and red: recessive

Eye color:

brown: dominant

blue and green: recessive

Hair type:

straight: dominant

curly: recessive

Now, since blue eyes are a recessive gene, it means that the mother has two "blue eyed genes" and the father has two "blue eyed genes" (technically they're alleles, I'm just simplifying the terms). Thus, the baby can only inherit blue eyed genes. The only chance of them having brown eyes is if a freak mutation occurs, which is incredibly incredibly unlikely. Incidentally, it's perfectly possible for two brown eyed people to have a blue eyed baby, because the gene for brown eyes is dominant, meaning both parents could have one brown eyed gene and one blue eyed gene, so the baby would have a one in four chance of having blue eyes.

As an example of that, let's say that brown eyes is shortened to a capital B, and blue eyes is a lower case b. You get one gene from each parent, thus you've got four possible combinations if both parents have brown eyes, but have one blue eyed gene and one brown eyed gene each. You could have: BB (two brown eyed genes), Bb (one blue eyes gene, one brown eyed gene), bB (one blue eyes gene and one brown eyes gene), and bb (two blue eyed genes.)

Let's say:

1) baby gets one B brown-eyed gene from dad, and one blue-eyed gene b from mom. Their genes would be Bb. Since brown eyes are dominant, the baby will have brown eyes.

2) baby gets one b blue-eyed gene from dad, and one brown-eyed gene B from mom. Again, the baby's gene is bB (or rather Bb), and it will have brown eyes.

3) baby gets one B brown-eyed gene from dad, and one brown-eyed gene B from mom. The baby's genes are BB, thus they will have brown eyes, and furthermore, they can't grown up and have a blue-eyed baby someday, because they're not a carrier of the blue eyed gene.

4) baby gets one b blue-eyed gene from dad, and one blue-eyed gene b from mom. The baby's genes are bb. The baby will have blue eyes, and their offspring will have at least one blue-eyed gene themself some day.

Hopefully that makes sense, and the difference between two blue-eyed people hypothetically 'having a brown-eyed baby' and the fair chance of two brown-eyed people having a blue-eyed baby is clear.

Answer 4

Yes, it is possible for parents with blue eyes to have a baby with brown eyes if they both carry the gene for brown eyes, which can be passed down to their child. Eye color is determined by a combination of genetic factors, so variations in eye color among children of the same parents are possible.

Answer 5

Yes. Possibly, if your mother's father or your father's mother had brown eyes or even if your partner or mate has brown eyes it is possibly.

Answer 6

It means you both carried the gene for blue eyes as a recessive gene. She inherited the recessive gene from both of you, which caused her to have blue eyes.

Answer 7

Blue eyes and green eyes are caused by the same gene. The amount of melanin in the eye determines the eyes color.

Answer 8

no
