Is eye color a homozygous recessive genetic disorder?
Blue eyes - homozygous recessive Brown eyes - homozygous dominant Brown eyes with one brown allele and one blue allele - heterozygous
When an allele mask the presence of another allele it is said to be?
Dominent. Simple- you have two types of Alleles, Dominent and Reccessive. Imagine a punnet square for the allele that causes albinoism (A). One parent has Aa, or one dominent allele and one reccessive allele for the trait. If the dominent skin-tone gene wasn't there (A), then it would be AA and he would be an albino. But since he has a dominent allele, he has normal color. If he made a baby with another Aa combination, they would have 25% chance of having an AA baby with no reccessive allele, a 50% chance of having an identical Aa combination, and a 25% chance of having an albino baby, AA.
Why a plant with yellow pods can never be a hybrid?
Yellow pods are a recessive trait and for this type of trait to show in the phenotype, both alleles have to be recessive. If there was a recessive allele (yellow) and a dominant allele(green) as it shows in hybrid pods, then the dominant allele would be the one shown and the pod would be green.
A fly has two alleles for the color of its eyes The green allele is recessive and is represented by q The blue allele is dominant and is represented by p If 20 of 100 organisms are green what is?
A. 0.45 Apex
Can several alleles affect a single trait like eye color?
Alleles affect traits like eye color. Alleles for brown and blue eyes are dominant and recessive respectively. Individuals who have homozygous and heterozygous genotypes with the dominant allele will have brown eyes. However individuals are homozygous for the recessive allele will have blue eyes.
In pea plants individuals that are Pp for the alleles that code for flower color will have purple flowers What is the phenotype?
Pp, where P represents the dominant allele and p represents the recessive allele.
Suppose that the alleles for blue eyes in cats is recessive and your cat has blue eyes. what statement can you make about your cat's genotype for eye color?
A+ It is probably homozygous for the recessive allele.
Are alleles dominant or recessive?
Alleles are neither entirely recessive nor entirely dominate. An allele is any one of a number of alternative forms of the same gene on a chromosome.For example: say a flower only blooms either red or white flowers. There is a different allele for each color-- a red allele and a white allele. Now, one color may be dominate over the other recessive gene. For example, if the red color was dominate and the white color was recessive, then those certain alleles would be dominate and recessive, respectively. But alleles in general cannot be either recessive or dominate. It depends on the gene and it depends on the trait.
What Suppose that the allele for blue eyes in cats is recessive and your cat has blue eyes What statement can you make about your cat's genotype for eye color?
it is probably homozygone for the recessive allele.
Suppose that the allele for blue eyes in cats is recessive and your cat has blue eyes. what statement can you make about you cats genotype for eye color?
it is probably homozygous for the recessive allele
What is a example of a recessive allele?
Solid color in cats. Two brown tabby cats might produce a solid black kitten, if they both carry the recessive allele for solid color (which is called "non-agouti").
What is the color of the baby eyes if the mother have the recessive gene for blue and the father has blue eyes?
I assume you mean the mother has a dominant allele for some other color. Father is homozygous recessive for blue. Dominant allele + recessive blue X recessive blue + recessive blue The baby has a 50% chance of blue eyes and a 50% chance of getting the dominant colored eyes.
Is eye color a homozygous recessive genetic disorder?
Blue eyes - homozygous recessive Brown eyes - homozygous dominant Brown eyes with one brown allele and one blue allele - heterozygous

What is dominant and recessive allele?
A dominant allele is an allele where its phenotype will always be represented when the allele for that gene is present. A recessive allele can be masked by a dominant allele when a dominant and recessive allele are present for the same gene. A recessive allele will only present itself when two recessive alleles for a trait are present.
What is red green color blindness mutation pattern?
what type of mutation is caused by red green color blindness?
What is the difference between dominant and recessive alleles on the basis of DNA?
Dominant alleles override recessive alleles. For instance, if there is both a dominant allele and a recessive allele present the dominant allele will be the trait that you end up with. If you have two recessive alleles, then you will have the recessive trait. :::::::::::::::brown eyes overrided blue eyes, because they are darker:::::::::::::::::: usually a darker color overpowered/override the lighter ones....i dont really know why but my science teacher said so......
