The genotype for a brown-eyed homozygote would be BB, where each allele represents the gene for brown eye color.
Since the female has blue eyes, she must be homozygous for the blue-eyed allele. Therefore, her genotype would be bb.
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.
Jimmy Buffett did not sing "Brown Eyed Girl." The song "Brown Eyed Girl" was actually performed by Van Morrison.
A genotype can tell what genes you have in your chromosomes. Genotypes really means what are all your genes and phenotype is what you see. You may have brown eyes. Your genotype might show that you have brown and blue genes for eye color but you see only brown.
They are related to each other because...Genes and alleles are the traits inside an object, when using a punnet square, we take the genotype out of that object to make experiments.
The mother's genotype is rr. The daughter would inherit one recessive allele from her mother because her mother has only recessive alleles. Because the daughter is green eyed, she would inherit a dominant allele from her father. The brown-eyed daughter's genotype would be Rr.
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.
A genotype is having a specific gene pair. A phenotype is a specific appearance. For instance, with eyes, the brown gene is dominant over the blue gene, so a person with the brown-brown, brown-blue or blue-brown genotype will have a brown-eyed phenotype. If they have a blue-blue genotype, they will have a blue-eyed phenotype. (it's actually way more complicated, because there's a number of eye color genes and there's a hierarchy (or possibly even a cyclical network (a la rock paper scissors - brown>blue>green>brown)) of dominance in the genes, but you get the idea.)
A heterozygous genotype has two different alleles for a given gene, one inherited from each parent. For example, in the genotype Aa, the individual has one dominant allele (A) and one recessive allele (a) for that gene.
A simple way to demonstrate the possibilities of the eye color of the offspring is to divide the potential outcomes into four categories, pairing two chromosomes into each. The outcome is three to one that the child will have brown eyes.
yes, if his wife is brown eyed
The brown-eyed person likely has the genotype Bb for eye color, where B represents the brown allele and b represents the blue allele. Since the mother is colorblind (XbXb), she contributes an X chromosome with the colorblind allele. The father with blue eyes (bb) does not affect the X-linked colorblind trait. The engaged partner, being colorblind with a normal-vision father (XbY), would also have the genotype XbXb.
yes, only 2 blue eyed people can only have a blue eyed baby, this will not change ever! where as 2 brown eyed people can also have a blue eyed baby, but for 2 blue eyed people to have a brown eyed baby is impossible!
Brown Eyed Girl was created in 1967-06.
Since the female has blue eyes, she must be homozygous for the blue-eyed allele. Therefore, her genotype would be bb.
The white eyed female fruit fly has two recessive traits for eye color. The genotype would be xx for example.
Yes, I have a son that has green eyes. I have blue, his father has brown.
