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?
If red is the dominant hair color and the father has brown hair (recessive trait), while the mother has red hair, the child's hair color is likely to be red, as the dominant trait of red hair from the mother would override the brown hair gene from the father. The child would inherit the dominant red hair trait from the mother.
Can a brown eyed father and a green eyed mother produce a green eyed child?
Yes, it is possible for a brown eyed father and a green eyed mother to produce a green eyed child. Eye color is determined by multiple genes, so the combination of these genetic factors can result in a child having a different eye color than either parent.
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%.
If a brown-eyed mother and a blue-eyed father have four children three will probably have brown eyes. What can you conclude from this?
Brown eyes are dominant traits
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?

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?
If red is the dominant hair color and the father has brown hair (recessive trait), while the mother has red hair, the child's hair color is likely to be red, as the dominant trait of red hair from the mother would override the brown hair gene from the father. The child would inherit the dominant red hair trait from the mother.

If the father has red hair and the mother has brown hair what color will the hair of their child be?
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!

A child has brown hair and brown eyes His father has brown hair and blue eyes His mother has red hair and brown eyes The best explanation for the child having brown hair and brown eyes is that?
The child inherited both the genes for brown hair and brown eyes from both parents, as brown is likely a dominant trait in this case. The child also carries the genes for blue eyes from the father and red hair from the mother, but the dominant brown traits are expressed in the child's appearance.
