In the process of DNA replication, a cell may get an erroneous copy of the original DNA. The error(s) sometimes happen in a critical spot that may affect, among other things, the growth of eyes. :D
Yes. Blue eyes are a recessive genetic trait, which means that a brown- or green-eyed person can still carry a gene for blue eyes. In this case, the blue-eyed gene is recessive, or subordinate, to the green- or brown-eyed gene. To be blue-eyed, an individual must have a recessive blue-eyed gene from both its mother and father.
In this case, the genotype of the white-eyed male fruit fly would be XwY, and the genotype of the heterozygous red-eyed female fruit fly would be XRXw. The expected ratio of genotypes in the offspring would be 1:1 for XRY (red-eyed males) and XRXw (red-eyed females).
All the offspring will have red eyes because the trait for red eyes is dominant and the female is heterozygous (carrying one dominant red eye allele). White eyes are recessive, so the offspring would need to inherit two white eye alleles to have white eyes.
NO. People with blue eyes do NOT have the brown eyed gene, if they did they themselves would have developed brown eyes instead of their blue as it is dominant. So two blue eyed parents can only pass the blue gene to their offspring.
All the offspring had red eyes. The white eye trait is recessive, so it did not appear in the offspring.
Brown. My sister and I both have brown eyes. My grandparents on my fathers side and my grandmother on my mothers side were all blue eyed. My mother and her father had brown eyes. The genes for brown eyes are more dominant.
A green eyed mother and a blue eyed father can have a child with blue eyes.
Well, it coud. If the plane of cell division of cells committed to be eyes was distorted, of if optical development itself was disturbed.
yes
Yes, it is possible for a green-eyed father and a brown-eyed mother to have a brown-eyed son. Eye color is determined by multiple genes, so offspring can inherit eye colors different from either parent based on the combination of genes they receive.
If a child has a mother with green brownish eyes, also known as hazel, and a blue eyed father, the child could have hazel or blue eyes depending on what the dominant genes are.
Brown eyes are dominant traits
Yes. Both parents could have the gene for green/blue eyes as a recessive gene.
Yes, because if there are any family members with blue eyes there may be a ressesive gene Causing the child to have blue eyes
Yes, it is possible for a blue-eyed mother and father to have a brown-eyed baby. Eye color is a complex trait influenced by multiple genes, so offspring can inherit a combination of eye colors from their parents. Brown eyes are a dominant trait, so if both parents carry a recessive gene for brown eyes, their child could have brown eyes.
Most likely hazel or green. Blue eyes are a recessive gene, so it is very possible for two brown-eyed parents to have a blue-eyed child.
Yes, it is possible for a brown eyed father and a green eyed mother to produce a green eyed child. Eye color is determined by multiple genes, so the combination of these genetic factors can result in a child having a different eye color than either parent.
