What are the two recessive alleles for blue eyes?
Blue eyed people have two recessives for blue. It is expressed as bb. A person with brown eyes is BB. Brown is dominate over blue. However a person with brown eyes can carry the gene for blue and they would be called Bb.
Can a blue eyed man and a brown eyed woman make a blue eyed kid?
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.
What is the best way to die fabric from blue to brown?
To dye fabric from blue to brown, you can use a combination of orange and green dye to neutralize the blue color and create a brown shade. Start by overdyeing the blue fabric with orange dye to cancel out the blue tones, then apply a green dye to shift the color towards brown. Experiment with different dye ratios and concentrations to achieve the desired brown hue.
Can a brown eyed man and a brown eyed woman have a blue eyed baby?
Yes, because your genes have both dominant and recessive traits, so you may have 1 blue and 1 brown and your wife may have 1 blue and 1 brown and (and this is gross simplification) when your genes combine if even one of your brown traits gets passed onto the child it will have brown eyes.
If a man had black hair and blue eyes and the woman had blond hair blue eyes can the child come out with brown eyes blond hair if the grandmother had brown eyes?
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.
What if your friend has blue eyes her genes contain one allele for blue eyes and one allele for brown eyes which allele is recessive how do you know?
The brown allele is recessive. Think: Blue = B, and brown = b Your friend is Bb, or heterozygous for the gene. In heterozygotes, the expressed phenotype is the dominant gene, which in this case, apparently, is blue. Thus, because your friend does not have brown eyes, the brown allele must be recessive.
