PATHOLOGY

Detailed explanation-1: -Answer: There is generally 25% chance that the baby will have blue eyes. If two parents have brown color eyes, then it may happen. This is usually consider with the biggest choice and thus carry out further approach for less than 1% chance of having baby having blue eyes.

Detailed explanation-2: -If both the parents have brown eyes, then there is generally a 25% chance for their child to have blue eyes. Because both the brown-eyed parents have a recessive blue-eye gene and can pass it to the next generation. However, since eye color is polygenic, several other genes exert their effects as well.

Detailed explanation-3: -The only way to present blue eyes is to inherit two copies of the blue-eyed gene. However, brown-eyed parents can pass a recessive blue-eyed gene. Therefore, two brown-eyed partners can birth a blue-eyed baby.

However, if the parents have a parent with blue eyes, the child has a small chance of having blue eyes, too. If one parent has brown eyes and one has blue, the child could have either one.

Detailed explanation-5: -If two individuals who are heterozygous have children, then one would expect that 25% of their children would have blue eyes. For each child, there is a 25% probability of the child having blue eyes if both brown-eyed parents are heterozygous.
