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. It depends on what the parents carry as a recessive gene.
If your mother had brown eyes and her father had blue eyes what would the baby have?
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.
What color hair wil the baby have if the mother has brown and father has red hair?

Yes. Brown is the domanent color. Look at his parents and her parents eyes. what colors do they have?
What color eyes and hair will baby have if mother has red hair and green eyes and father has brown hair and green eyes?
The baby could have green eyes like both parents, and may have red hair like the mother or brown hair like the father. The combination of genes from both parents would determine the baby's specific eye and hair color.
What color hair will a baby have if a mother has brown hair and the father has like a red more brown color?
my parents had the sme hair colors and i ended up with a redish brown with natural higlights of blonde (no idea how) and red
What color Eyes will a baby have if the mother has blue eyes and the father has Red Eyes?
A baby cannot have red eyes, as red eyes are not a natural eye color in humans. If a mother has blue eyes and the father has a red-eye color, the baby will most likely have blue or green eyes, as blue is a recessive trait and would be dominant over a hypothetical red trait.
