What is an example of 2 alleles?
The blue eyed gene and the brown eyed gene in humans.
What do you think the possible alleles for eye color in humans?
The possible alleles for eye color in humans are typically variations of the genes that control the production of melanin, such as the OCA2 and HERC2 genes. Common alleles include those for brown, blue, green, and hazel eyes. The combination of these alleles contributes to the wide range of eye colors observed in the human population.
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.
How do combination of alleles on your genes determine your phenotype?
Your phenotype is a characteristic of how you look, for example if you have brown or blue eyes. You inherit one allele for each characteristic you have from you mom and dad. Say your mom gives you a blue eyes allele and your dad gives you a brown eyes allele. Since brown eyes usually dominate over blue eyes, you would most likely be heterozygous for brown eye color, and you would have brown eyes. This would be represented by Bb, the B standing for brown eye color, the dominant trait, and the b standing for blue eye color, in this case the recessive trait. So, depending on what alleles you receive from your parents, you may look different than, for example, than your siblings do because they got a different set of alleles. This is possible because your parents both have 2 alleles, but they only give you one of each, so if both your parents give, for example, your sister a blue eye allele, she will most likely have blue eyes, even if you have brown.
Can someone with brown eyes and one with green eyes have a blue eyed child?
It is possible for a child with a brown-eyed parent and a green-eyed parent to have blue eyes if there is the trait for blue eyes in the child's genetics. Such as a grandparent with blue eyes.
If a blue eyed women has a child with a brown eyed man what color will the child's eyes be?
It Depends what the domionant colour is you can draw a punnet square and find out the chances =] but it will either be brown or blue obvii
Why did Hitler want to get rid brown hair blue eyed people?
Because the combination of brown hair blue eyes is strange. The person would get two dominant alleles for brown hair and two recessive alleles for blue eyes. It is not supposed to happen.
What is meaning of alleles?
An allele is the different forms of a gene. For example the gene for eye colour has the alleles; brown, blue, green etc. In every person there are two alleles for every gene but both alleles are not always the same. They can be dominant and recessive; dominant alleles are expressed no matter what other allele is present, recessive alleles require both alleles to be the recessive one to be expressed. E.g. say B is the allele for brown eyes and b is the allele for blue eyes. Brown is dominant therefore if someone had Bb or BB they'd have brown eyes and if they had bb their eyes would be blue.
What are the different forms of a gene called?
Alleles are the different forms of a gene.Alleles are corresponding pairs of genes located at specific positions in the chromosomes. Together, alleles determine the genotype. Alleles which determine some aspect of the phenotype, the physical appearance of an organism, are said to be coding alleles.When both alleles in a pair are the same, the alleles are homozygous. If the alleles are different, they are heterozygous. In the case of homozygous alleles, the expression of phenotype is usually very straightforward. In heterozygous instances, however, the phenotype of the organism is determined by which allele is dominant, meaning that one allele overrides the other.In the case of eye color in humans, if someone inherits a blue allele and a brown allele, his or her eyes will be brown, because brown is a dominant genetic trait, requiring only one allele for expression. However, if that person had a child with someone who also carried a blue allele and both parents passed the blue trait down, the child would have blue eyes. This explains why blue-eyed children sometimes randomly pop up in a brown-eyed family: because someone in the family's genetic history had blue eyes.

The blue eyed gene and the brown eyed gene in humans.
Why can a person with brown eyes carry blue eye alleles but a person with blue eyes cannot have a brown eye allele in their genotype?
A person with brown eyes can carry the blue eye allele because brown is a dominant trait, so they can have both blue and brown alleles in their genotype. However, a person with blue eyes cannot have a brown eye allele because blue eyes are a recessive trait, meaning they must have two copies of the blue allele in their genotype to express the trait.
What is it called when an organism inherited two of the same alleles of a gene from its parents?
Then you will have two copies of the same gene, a condition known as having identical alleles. If the particular gene is recessive (such as for blue eyes) this is the only way it will be able to express itself.
Your whole family has blue eyes but his all have brown what about my child?
Your child has a 25% chance of blue, 75% chance of brown

Difference between a gene and an allele?
The alleles are the different forms of the gene. This is simplified, but an example might be, if the gene is "eye color," the alleles would be "green, blue, brown, etc." The variations in the gene are the alleles.
