Will my children have red hair and blue eyes?

CaliGrlatH

I am of Hispanic descent, I have brown hair and brown eyes. My fiancé is of scottish descent, has blue eyes and red hair. What are the chances of my children having red hair or blue eyes?

Answer
Brown eyes are almost always dominant over blue eyes. So most likely he will have brown eyes. But could still have blue eyes which is pretty rare. Now with the hair color the baby gets the genes from both parents so it could be either brown or red hair. You have 50/50 chance. But say your family has all brown hair and his family is scattered with red hair and brunettes. You would mostly likely have the dominant gene. You could also get genes from grandmother or other relative in the family.

Can black people have red hair and green or blue eyes?

Answer
Yeah. It's rare though.
Red hair is more likely in black females.
Blue Eyes are more likely in black males.
Green eyes are more likely in black females but only by a small percentage.

Like her for example:

You need to have the gene passed on though. From one that has the genetic mutation.

Q. Blonde hair and Brown eyes OR Blonde hair and green/hazel eyes
Black hair and Caribbean blue eyes OR Black hair and emerald green eyes
Brown hair and Blue eyes OR Brown hair and green eyes
red hair and Brown eyes OR Red hair and Blue eyes?

Answer
Blonde hair and brown eyes--the other choice is too "the girl next door"
Black hair and emerald green eyes--the other choice is too weird looking.
Brown hair and blue eyes is gorgeous :)--green eyes and brown hair is too boring,
Red hair and blue eyes is sooo cute--brown eyes don't match.

If the father has blond hair and blue eyes, but the mother has red hair and gray eyes?

If the father has blond hair and blue eyes, but the mother has red hair and gray eyes?
What color hair and eyes will the kids have?

Answer
First a little science
Red hair is caused by a mutation on chromosome 16 which is thought to regulate about 3% of the DNA in the human body including pigment production.
This mutation alters the type of pigment that is produced.

In our bodies we have something called a melanin-activating peptide receptor (MC1R) which takes queues from the body chemicals and tells the cells in your hair, eyes and skin to produce the appropriate pigment.

If you get someone who has this mutated chromosome then the MC1R is sent a different signal to normal and essentially it is turned off so it isn't telling the hair, skin and eyes to produce a dark pigment like it normally would (brown or black eumelanin which causes dark hair, eyes and skin).

------------------

Now why does this cause red hair?
Red hair is the result of brown hair acting under the influence of this mutated chromosome. It is essentially brown hair (which normally contains a mix of brown eumelanin, red phaeomelanin and a little yellow phaeomelanin) but the dark brown eumelanin has been turned off so it isn't being produced properly, auburn hair is the result of a partially active receptor and ginger hair is the result of a completely inactive receptor.
The person with red hair really carries the gene for brown hair but also carries the mutated chromosome.

This mutated chromosome is recessive and requires to copies to be seen as a phenotype acting on the hair, if there is only one copy of the chromosome then it is a genotype and has no effect on the hair color.

--------------------

Now back to your original question.
Because this mutation is rare and very recessive, the chances are that the child would inherit blonde or brown hair rather than red (unless red hair is known on both the mother and father's side in which case it's much more likely for the child to have red hair)
However they will carry the unseen and inactive mutation for red hair which could surface in later generations if matched with another carrier of the the same mutated chromosome.

A similar effect is happening with the eyes which are also influenced by this same mutated chromosome, grey eyes are recessive over blue and it's far more likely that the child would inherit blue.
