There's a 50% of chance that the children's eyes will be brown.
Kittens are often born with blue eyes. They later change to brown.
50% of the cross would be brown eyes and 50% would be blue eyes
Yes, as long as one of their Grandparents/ Great Grandparents has blue eyes. If both pairs of Grandparents have brown eyes then it is VERY unlikely :)
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.
yes
Deborah Sampson's favorite color is purple
green and brown
Blue eyes are a recessive trait. If at least one of the parents had a blue/hazel eyes with a mixture of blue and brown, then the couple's offspring could have brown eyes. If both parents had solid blue eyes, neither would have the dominant brown gene to pass to the baby, and it would have blue eyes, regardless of the grandmother's eye color.
