What term describes a gene with two dominant alleles that are expressed at the same time?
Co-dominance.
If two dominant alleles are expressed at the same time this is a case of what?
This is called codominance. In codominance, both alleles are fully expressed in the phenotype of the individual.
Two identical alleles for a particular gene is what?
Having two identical alleles for a particular gene is known as homozygous. This means that both copies of the gene are the same, either both dominant or both recessive. Homozygosity can result in a specific trait being expressed, depending on the nature of the alleles.
What is the difinition of alleles?
An allele is a form of a gene. For example, the allele B may lead to black fur and the allele b may lead to white fur. Both B and b are alleles for fur colour.In general notation, dominant alleles are written with a capital letter (eg. B, T, P) and recessive alleles are written with a lower case letter (eg. b, t, p). A person will have two alleles (one from each parent) for every gene. Dominant alleles are expressed over recessive alleles.
What is the relationship between dominant and recessive alleles in a heterozygous organisms?
it means there is one of each. in a homozygous gene it means that there are two of the same. for example if "t" repressents a recessive trait and "T" represents a dominant trait, then an organism with a gene that is tT would be considered heterozygous, and a gene that is TT or tt would be considered homozygous or "pure bred"

Co-dominance.
Is a recessive gene expressed?
Ok, im assuming your question is "if two recessive alleles are present will the trait be expressed" A trait will be expressed if two alleles are recessive but it will not be the same representation as two dominant alleles. For example, T being a tall pea plant and t being a small pea plant. Two recessive alleles or, homozygous recessive, alleles The other option would be there is one dominant and one recessive, heterozygous, which would look like Tt. This would take on the trait of the dominant allele usually expressed by the capital letter. So this heterozygous plant would be tall.
How do you distinguish between genotype and phenotype heterozygous and homozygous and dominant and recessive?
Genotype is the organism's full heredity information that may or may not be expressed. Actual observed properties are the phenotype. The phenotype is dependent on the genotype. Genes are homozygous when the same allele (form of the gene) inherited from both parents is the same. When different forms of the same gene are inherited from parents, they are heterozygous. Dominance refers to the relation between alleles of a gene. When two alleles of a gene combine, the dominant one then determines the trait that is expressed. In order for a recessive trait to be expressed, both alleles need to be recessive.
What are the different forms of the same gene?
i dont know thats why im asking
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.
If two dominant alleles are expressed at the same time this is a case of what?
This is called codominance. In codominance, both alleles are fully expressed in the phenotype of the individual.

What name is given to different forms of same gene?
Alleles are different forms of the same gene, each producing a unique variation of a specific trait. Alleles can be dominant or recessive, and individuals inherit two alleles for each gene, one from each parent.
How are dominant and recessive genes related?
Dominate them. Recessive alleles do not show in your phenotype unless you have two of the same recessive allele. But if you inherit one dominant and one recessive, it is the dominant that always shows in your phenotype.
Define Dominant Recessive Homozygous Heterozygous Purebreed and Hybrid?
Dominant: The trait observes when at least one dominant allele for a characteristic is inheritedRecessive: A trait that is apparent only when two recessive alleles for the same characteristic are inheritedHomozygous: Two of the same alleles for the same alleles (RR or rr)Heterozygous: Genotypes made of two different alleles (Rr)Pure breed: same definition as homozygousHybrid: same definition as Heterozygous

What is the difference between two alleles of the same gene?
The difference between two alleles of the same gene is that they are variations of the same gene that can result in different traits or characteristics. Alleles can be dominant or recessive, and individuals inherit one allele from each parent. These variations in alleles can lead to differences in physical traits or characteristics in an organism.
