Not 100% sure about the hair colour part of the question, but i can tell you that it is impossible for two blue eyed parents to have a brown eyed child. It is possible for one parent with brown eyes and one with blue eyes to have a blue eyed child though. The blue eye trait is caused by both parents having nothing other than the blue eyed gene which thereby means that if both parents only have blue eyed genes than their offspring can only have blue eyes.

Two blue-eyed parents can have a child with brown eyes. Most of us learned the model for determining eye color that G.C. Davenport and C.B. Davenport devised in 1907. The Davenport model wrongly says brown eye color is always dominant over blue eye color, which means that two blue-eyed parents always have blue-eyed kids. We know better now. "Although not common, two blue-eyed parents can produce children with brown eyes," says Richard A. Sturm, a Principal Research Fellow at the Institute for Molecular Bioscience at the University of Queensland in Brisbane, Australia.

Eye color is a complex trait that depends on the state of several interacting genes. The gene that usually decides the issue (blue eyes or brown eyes) is the OCA2 gene on chromosome 15. But it comes in different strengths. A person with a weak form of the OCA2 gene will have blue eyes. Likewise a person with a strong form will have brown eyes. The plot thickens, though, because an individual also has other eye-color genes that each has a say in the final eye-color outcome. For example, if one of these lesser genes is strong, it can make the weak form (blue) of OCA2 work much more effectively - almost like the strong form (brown). Then the eye color may be a light brown or muddy grey. In fact, the resulting color can be any shade of brown, hazel/green, or blue depending on the strengths of the interactions.

Are blue eyed blonde's rare?

In Germany, NO! About 80% has that combination. I am blond haired and blue eyed, and just finished doing some research on this. Blond hair and blue eyes are a rare combination in the USA, so I feel special... :)

What colour hair will the baby have if the father has fair hair and the mother has black hair?

The answer to this question depends on their parents' hair colors. If both have a blond (or red) haired parent, it is possible they could have children with blond (or red) hair. The black is more dominant than brown, so if the black haired parent has two black haired parents it is much more likely they will have black hair or the black has about 65% the brown has 35% so it will be a mix of black and brown probably black with a bit of brown i was learning about DNA

If a man had black hair and blue eyes and the woman had blond hair blue eyes can the child come out with brown eyes blond hair if the grandmother had brown eyes?

Blue eyes are a recessive trait. If at least one of the parents had a blue/hazel eyes with a mixture of blue and brown, then the couple's offspring could have brown eyes. If both parents had solid blue eyes, neither would have the dominant brown gene to pass to the baby, and it would have blue eyes, regardless of the grandmother's eye color.


If both parents have brown hair and eyes can there baby have blond hair and blue eyes?

yes it is very possible. it all has to do with a gene pool but simply YES! -Actually, it is theoretically impossible. Blonde hair is a recessive trait, so both alleles must be the same, represented here as "hh". In order for the eyes to be brown, a dominant trait must be present, represened as "H" here. So it would either have to be Hh or HH. However, if both parents have blonde hair, there can only be two "hh"s in the gene pool. When the egg is fertilized, the only possible traits on the gametes are "h"s. There can be no dominant genes, since both parents have blonde hair and the brown hair gene would mask the recessive blonde gene. And the same goes for eyes, since blue is recessive in eye color and brown is dominant. The blue eyes are indicated with a "bb", and brown eyes as either "Bb" or "BB". Since both parents have blue eyes, the only possibility for each parent is "bb", and each parent giving on allele means one parent can give b or b, and the other parent can only give b or b. No matter how it goes, the end result will always be "bb". So to summarize, no. Two parents that display a recessive trait always produce an offspring showing that trait. Two brown-haired brown-eyed parents can, however, have a blonde-haired blue-eyed child, if both parents are heterozygous, meaning have "Hh" and "Bb". I hope this answer made sense to you, and that I explained it well and didn't ramble to an excessive degree.


If you have brown eyes and black hair you carry reddish-brown hair and hazel eyes traits and your mate has blonde hair and blue eyes what will the child look like?

Well your child will have a 50-50 shot at being either dark haired and dark eyed or being blond haired and blue or hazel eyed.


What color eyes and hair will a baby most likely have if the father has blonde hair blue eyes and the mother has brown hair green eyes?

The Baby will almost definitely have brown hair and brown eyes. If the father has a blonde haired gene or blue eyed gene (if one of his parents or grand parents had blonde hair and blue eyes) there is a possibility the baby will have blonde hair and blue eyes (one in four chance).


What is the likelihood of having a blue-eyed baby with blond hair if the mother and father both have blue eyes with brown hair that was blond from birth-6 years old?

blue eyes very likely, blond hair, not lucky- will turn out brown as brown hair is the dominant allele in a brown-blond pair of alleles (see genetics, hair color, wikipedia). Hi, no I don't agree because I have brown hair now but I was properly blond til I was 6 years old. Both my parents had brown hair. I am English (and by that I mean properly English - not muslim) and like 90% of ethnically English people, have blond hair when young that darkens with age. This is due to the English race being Germanic and related to the Germans, Danes, Norwegians etc. In the US, there are lots of people with either English or German ancestry - so much the same story there too. I do not know about English race, ancestors and genetic traits, nor the genetic background of the darkening blond hair, however if both parents have brown hair, it means that they carry at least one dominant gene that expresses brown hair. Still, if both parent have also one recessive allele for blond hair, theoretically there is a 25% chance that their children could be blond haired, and of course with blue eyes.

Can a hazel eyed brown haired father and a blue eyed brown haired mother have a blonde haired blue eyed child?

This can definitely happen because of the concept of genetics. This especially deals with dominant and recessive traits. If both parents have one dominant trait and one recessive trait (causing dark hair and eyes) and both parents give their child the recissive traits, this outcome is possible (although pretty rare it is seen).
