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.
Probably brown.
brown eyes because brown is the dominant color :)
i m pretty sure that child will have purple eyes
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. MORE like 5-1 his here will be blond
The genetics of eye color are more complex than previously understood. Almost any parent-child combination of eye colors can occur.
It depends on the genes but most likely brown because the allele for brown eyes is dominant over all other alleles

Brown color of eye is dominant over blue color. If the mother is homozygous for brown color of eye, than the all the children will have brown color eyes. If mother is heterozygous for brown eyes, than 50% of children will have brown eyes and 50% will have blue eyes.
if mother has black and the father has red it will probally be brown
blue

Yes. Brown is dominant for eye color.
