Homozygous dominant- means having dominant alleles at the same locus on a chromosome.More correctly, it's the same locus on two chromosomes (a homologous pair).

What is the phenotype of AAA?

It's impossible to say without more information. The genotype AA is called homozygous dominant for the trait that is encoded by the letter A (or a). Whatever trait A stands for on your homework, the answer is the dominant one is expressed in the phenotype.


What is the type of allele that only effect the phenotype in the homozygous chromosome?

Recessive. Dominant alleles are expressed in both homozygous and heterozygous individuals (DD or Dd), but recessive alleles are only expressed in homozygous individuals (dd).


What gene is masked if it is paired with a dominant gene?

The different forms of a gene are called alleles. In Mendelian genetics, a gene has a dominant allele and a recessive allele. The dominant allele masks the recessive allele if present. So there are two possible dominant genotypes: homozygous dominant, in which both dominant alleles are present; and heterozygous, in which one allele is dominant and the other allele is recessive. The only way to express a recessive trait is to have the homozygous recessive genotype.


What is an allele that produce a trait in the heterozygous condition is?

homozygous


What is a person who has one recessive allele for a trait and one dominant allele for the same trait and is able to pass in the trait on to their offspring?

That is heterozygous. Some scientist call these "hybrids"(no joke)The person is heterozygous for that trait and will have the dominant phenotype.An organism with both a dominant and recessive allele for a specific trait is called an heterozygote. They are heterozygous for this trait.

Is homozygous dominant a geneotype or phenotype?

homozygous dominant is the genotype. hypothetically, if the gene was for the color purple in a flower, the phenotype would be purple, while the genotype would be homozygous dominant AKA Pp.


What is the probabilty that the offspring of a homozygous domiant idiviual and a homozygous recessive indiviual will exbhit the domaint phenotype?

If one parent is homozygous dominant (AA) and the other parent is homozygous recessive (aa), all offspring will inherit one dominant allele and display the dominant phenotype. Therefore, the probability of their offspring exhibiting the dominant phenotype is 100%.


What Alleles that display equal power in determining a phenotype?

Homozygous dominant and heterozygous both are a dominant phenotype.


What is the probability that the offspring of a homozygous dominant individual and a homozygous recessive individual exhibit the dominant phenotype?

Given those conditions, the offspring have a 50% chance of demonstrating the dominant phenotype and a 50% chance of demonstrating the recessive phenotype.


What is the probaility that the offspring of a homozygous dominant individual and a homozygous recessive individual will exhibit the dominant phenotype?

100 percent.


What phenotype is produce by each of the following genotypes?

Genotype: AA - The phenotype is homozygous dominant, exhibiting the dominant trait. Genotype: Aa - The phenotype is heterozygous, exhibiting the dominant trait. Genotype: aa - The phenotype is homozygous recessive, exhibiting the recessive trait.


What is crossing a homozygous dominant or homozygous recessive with a heterozygous?

There is a 50% chance of a homozygous dominant and a 50% chance of a heterozygous.


What is similar because the heterozygous phenotype is different from the homozygous dominant phenotype?

Both heterozygous and homozygous dominant genotypes have the same dominant allele, resulting in a similar overall phenotype. The difference lies in the fact that heterozygous individuals have one dominant and one recessive allele, leading to a different genotype than homozygous dominant individuals who have two dominant alleles.


To determine the genotype of an individual that shows the dominant phenotype you would cross that individual with one that is?

To determine the genotype of an individual that shows the dominant phenotype you would cross that individual with one that is homozygous recessive. A monohybrid cross of two individuals that are heterozygous for a trait exhibiting complete dominance would probably result in a phenotype ratio is 3 dominant 1 recessive.


What is the percentage of offspring that will exhibit the dominant trait from A crossing of A homozygous dominant and homozygous recessive individual?

The homozygous dominant individual can only pass on the dominant allele and the homozygous recessive individual can only pass on the recessive allele, therefore all offspring will be heterozygous and have the dominant phenotype.


What phenotype is produced by AB genotype?

The genotype AA represents a homozygous dominant genotype. The capital letter "A" represents the dominant allele, while the lowercase letter "a" would represent the recessive allele. If both dominant alleles are present in a genotype (homozygous dominant) then the phenotype is "A" phenotype. If one dominant allele and one recessive allele are present (heterozygous dominant) then the phenotype is "A". Finally, if both recessive alleles "a" are present (homozygous recessive) then the phenotype is "a". Therefore, the answer to your question is the genotype AA would result in an "A" phenotype because the genotype is homozygous dominant.


A dominant phenotype will only be expressed if the individual is homozygous dominant for that trait?

Well actually not necessarily. An individual can be homozygous or heterozygous dominant for a trait. As long as they have that dominant allele in that specific genetic trait, they will automatically express the dominant phenotype. If a person is homozygous dominant, it just means that they will pass on both dominant traits to the offspring. If a person is heterozygous dominant , it means that they will pass on both a dominant and recessive trait to their offspring.Hope that helps ! =D
