Brown eye colour is dominant over blue eye colour. Therefore, for the brown-eyed parents having blue-eyed child, the possibility is that both have heterozygous genotype i.e. Bb. Therefore, from the square below, it is clear that there is a 25% possibility of blue-eyed (bb) child.

What is the probability of 2 brown-eyed parents having a blue-eyed child?

Both parents with brown eyes: 75% chance of baby with brown eyes, 18.8% chance of baby with green eyes, 6.3% chance of baby with blue eyes. Both parents with blue eyes: 99% chance of baby with blue eyes, 1% chance of baby with green eyes, 0% chance of baby with brown eyes.

Can a baby have blue eyes if the parents don t?

Both parents have to pass along the blue eye gene in order for their child to have blue eyes. That doesn't necessarily mean that the parents themselves have to have blue eyes; it's possible they carry the gene, but it is recessive. However, a blue-eyed child is almost certain if both parents have blue eyes.

What is the rarest eye color?

Gray: The Rarest Eye Color With this change, gray now tops the list as the rarest eye color. Gray eyes may contain just enough melanin in the front layer to dim the blue wavelengths of light that are reflected back by the tissue of the eye. Dark gray eyes have a bit more melanin in the front layer than pale gray eyes.

How do you get a blue-eyed baby?

Two blue-eyed parents are very likely to have a blue-eyed child, but it won't happen every single time. Two brown-eyed parents are likely (but not guaranteed) to have a child with brown eyes. If you notice one of the grandparents has blue eyes, the chances of having a blue-eyed baby go up a bit.

Can two brown eyes make a blue eye?

Brown eye colour is dominant over blue eye colour. Therefore, for the brown-eyed parents having blue-eyed child, the possibility is that both have heterozygous genotype i.e. Bb. Therefore, from the square below, it is clear that there is a 25% possibility of blue-eyed (bb) child.

How likely is it for 2 brown eyed parents to have a blue eyed baby?

Flexi Says: Two brown-eyed parents (if both are heterozygous) can have a blue-eyed baby. If both the parents have brown eyes, then there is generally a 25% chance for their child to have blue eyes. Because both the brown-eyed parents have a recessive blue-eye gene and can pass it to the next generation.

Frequently Asked Questions

What is the probability that a brown eyed couple has two children with blue eyes?

Answer and Explanation: The probability that both of the first two children will have blue eyes is 1/16. Because both parents are carriers of the recessive blue eye allele, there is a 1/2 chance that each parent will pass the blue eye allele on to a given child.

Can two brown eyed parents make Hazel?

If both the parents have hazel eyes, there are 99% chances that the baby will also have hazel eyes. If both the parents have brown eyes, there is a 75% chance that their child will have brown eyes.

Can 2 people with brown eyes have a blue eyed baby?

Both parents with brown eyes: 75% chance of baby with brown eyes, 18.8% chance of baby with green eyes, 6.3% chance of baby with blue eyes.

FAQ

What are the odds of having a blue eyed baby?
If both parents have blue eyes, then it's almost a 100% chance that their kids will have blue eyes. Now if one parent has blue eyes and the other has brown eyes, then there is a zero to 50% chance of the child having blue eyes."

What is the probability that a brown-eyed couple has two children with blue eyes?

What are the odds of two brown eyes make blue

Are brown eyes dominant over blue? Eye color was traditionally described as a single gene trait, with brown eyes being dominant over blue eyes. Today, scientists have discovered that at least eight genes influence the final color of eyes. The genes control the amount of melanin inside specialized cells of the iris.
How to have a blue eyed baby? Two blue-eyed parents are very likely to have a blue-eyed child, but it won't happen every single time. Two brown-eyed parents are likely (but not guaranteed) to have a child with brown eyes. If you notice one of the grandparents has blue eyes, the chances of having a blue-eyed baby go up a bit.
How can two brown eyes make a blue? If a mother and father both have brown eyes but each carry the repressive blue-eye allele (i.e. they are heterozygous), there is a chance that the offspring may inherit two blue-eye alleles: one each from the mother and father. Thus the child would have blue eyes.
  • Can two people with brown eyes have a blue-eyed baby Class 10?
    • Yes. The short answer is that brown-eyed parents can have kids with brown, blue or virtually any other color eyes. Eye color is very complicated and involves many genes.
  • What are the odds of having a blue-eyed baby?
