yes the blue eyes gene could have been passed down from another family mnember, not just by a parent.
It is possible for a child with a brown-eyed parent and a green-eyed parent to have blue eyes if there is the trait for blue eyes in the child's genetics. Such as a grandparent with blue eyes.
Brown, blue, or a mixture making a grayish blueish brown!
Yes, it is possible for a parent with blue eyes and brown eyes to have a child with blue eyes if both parents carry the gene for blue eyes. Eye color is determined by multiple genes, so it is possible for a child to inherit the blue eye color gene from both parents.
The blue eyed parents may have heterozygous genotypes with the dominant gene and recessive gene for blue and brown eyes respectively. During segregation of gametes, their is a likelihood that their child may inherit the recessive genes from both parents. Consequently, their child will have brown eyes.

Theoretically, a blue eyed man and a blue eyed woman cannot produce a brown-eyed child. The reason is that neither parent carries the brown-eyed gene. If the father or mother did carry the brown-eyed gene, the eyes/irises of that parent would be brown. The gene for brown is dominant over the gene for blue. However, two brown eyed parents can produce a blue eyed child. In that case, each parent with brown eyes must carry the gene for blue - the parents' eyes are brown because the brown gene is dominant over the blue gene. However, if the child inherits a blue gene from both brown eyed parents, the result will be blue eyes although both parents have brown eyes. In the case of one parent with brown eyes and one parent with blue eyes, there is a possibility that the parent with brown eyes possesses the non-dominant blue gene. If the child inherits the blue gene from that brown eyed parent, the child's eyes will be blue since the gene from the other parent with blue eyes will be blue. There is a condition known as heterochromia iridis where one eye is brown and one eye is blue. This condition is usually pathological on a neurogenic or inflammatory basis with the abnormality usually being in the lighter/ blue eye. Acquired heterochromia iridis that develops in an adult may suggest a melanoma of the iris in the brown eye.
It is genetically possible for two brown-eyed parents to have a blue-eyed child if both parents carry a recessive blue eye gene. If the mother's parent has blue eyes, it means she carries the blue eye gene, and this gene could be passed on to the child.
GeneticsYes, it's possible for a pair of blue-eyed parents to have a brown-eyed offspring. It all depends on each parent's genotype, and which trait comes from the dominant or recessive allele.
There is no way to tell for sure, they could have blue, green, or a mix (blue-green). Its even possible that the mom or dad could have some brown eye genes in the from previous ancestors and the kid could have brown eyes!
No. Blue eyes come from a recessive gene from each parent. The child must of 2 recessive gene pairs to have blue eyes (which is actually the lack of eye pigment). So a brown eyed parent and a green eyed parent may have a blue eyed child if both pass on a recessive blue eye gene, but if just one dominant brown or green eyed gene is passed along it will trump the recessive blue eyed gene and the child will have brown or green eyes.
Yes, because brown eyes are the dominate trait, blue eyes might be the "hidden trait." one of the grandparents have the hidden trait, they passed it onto the parent, and the the blue eyes trait became dominate in the child.
Yes, it is possible. If one parent has blue eyes, they must carry two blue eye genes (bb) and can only pass on a blue eye gene to their offspring. If the other parent does not carry any blue eye genes, their child has a chance of inheriting a blue eye gene from the blue-eyed parent. This would result in the child having blue eyes.
