Brown eye gene = B
Blue eye gene = b
Each person has two copies of the eye color gene in their genome, one inherited from each parent. Now if both parents only carry the gene for brown eyes, BB and BB, then their child will receive one B from each parent, ending up as BB. The same works for blue eyes, if that's the only gene both parents carry, bb and bb. Each parents gives on b to the child, who ends up as bb.
If you have one parent who only has the gene for brown eyes, BB, and one parent who only has the gene for blue eyes, bb, then all the children will have brown eyes. Example: One parent gives a B, the other gives a b. Bb = brown eyes. Here's why: When you have two alleles (coding sequences) from genes that are at odds with each other, one version will override the the other. When dealing with eye color, B always dominates b. But these children now carry the b gene in them, and could pass it down to their own children. Some of them, depending on the other parent, could end up with blue eyes.
If one parent is Bb, and the other is bb, then each time they have a child, there is a 50% chance it will have blue eyes. Example: First parent is Bb, second parent is bb, then their children will end up as either Bb, bb, Bb, bb. If both parents carry the genes for brown eyes and blue eyes, then each time they have a child, there is a 25% chance it will have blue eyes. Example: First parent is Bb, second parent is Bb, then their children will end up as either BB, Bb, Bb, bb.

If red is the dominant hair color but the father has brown hair and the mother has red hair and the hair color of the father is dominant then what color will the hair of their child be?
It's very hard to answer this question as there are no details on what alleles the fathers or mothers DNA contains. The father has to have an allele for red hair for the child to have a chance of having it. Presuming that the father has a brown and red hair allele and the mother has the same it works out like this. Brown + Brown = Brown Brown + Red = Brown (Because it's dominant) Brown + Red (from other parents) = Brown (Because brown is dominant) Red + Red = Red The chances of brown therefore is 3:1 as you cannot be sure on what the child will receive.

Can a blue eyed male with both his parents having blue eyes marries a brown eyed female with her mother having blue eyes and her father having brown eyes could they have a brown eyed child?

Probably brown.
Can a green eyed father and a brown eyed mother have a brown eyed son?
Absolutely. Brown eyes are dominant. Green is a mutation.
Which is the dominant gene father has dark brown eyes mother has blue eyes?
Sure you don't mean heterozygous dominant? If you don't there would be no blue eyed offspring. Let's assume you meant heterozygous dominant.B = brownbl = blueBbl X Bbl1/4 of the offspring would have blue eyes, 25%.
Your partner and you have brown hair your mother and his father have dark hair and your father and his mother have red hair. What are the chances of your kids having red hair?
most likely brown hair
What are the chances of a brown eyed mother and a green eyed father having a blue eyed child?

Well, it could be anything, really! It depends on whose genes the baby has the most of. Chances are, it will be brown, but there may be hints of red in it! Hope this helped!

yes
Blue eyed father brown eyed mother blue eyed grandfather of the father what color eye will offspring have?
