At is a gene with two dominant alleles that are expressed at the same time?
In genetics, gene with two dominant alleles that are expressed at the same time is known as codominance. This results in a phenotype where both alleles are equally and fully expressed in the offspring. An example of codominance is the AB blood type in humans, where the A and B alleles are both expressed on the surfaces of red blood cells.
A trait which results from two dominant genes is called?
It would depend on if the dominant genes are the same or different. Say the dominant alleles were different. In this case, they are co-dominant. If they are the same and both dominant homosytus.
What term describes a gene with two dominant alleles that are expressed at the same time?
Co-dominance.
What are the two types of alleles traits?
The two types of alleles for traits are dominant alleles and recessive alleles. Dominant alleles are expressed when at least one copy is present, while recessive alleles are only expressed when two copies are present.
What is the best term to describe the allele that is expressed over all other alleles of the same trait?
Dominant; genetics.

If a pea plant has two alleles YY. what is its genotype?
The genotype of a pea plant with two alleles YY is homozygous dominant. This means that both alleles for the trait in question are the same and dominant. In this case, the plant will express the dominant trait associated with the YY genotype.
A recessive allele is represented by an letter?
In genetics, a recessive allele is typically represented by a lowercase letter. For example, if the dominant allele is represented by "A", the recessive allele for the same trait would be represented by "a".
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 is a dominant trait represented in a punnett square?
Dominant alleles are written in upper case (i.e, 'A'), while recessive alleles are lower case (i.e, 'a')
Two dominant alleles are expressed at the same time?
The alleles are not always both expressed.Take the simplest example, a case when there are only two alleles for a trait, R and r. When the organism is a heterozygote, meaning that it has both alleles with a genotype of Rr, only the phenotype carried by the dominant allele, the R, will be expressed. The dominant allele masks the phenotype of the recessive allele. A case in which only the dominant phenotype is expressed in a heterozygote is a case of complete dominance.*Cases where the dominant allele does not completely mask the recessive allele are cases of incomplete dominance and co-dominance.In incomplete dominance, the dominant allele has some effect on the recessive allele, but not a full effect. This results in a third phenotype in the population. Think red and white flowers leading to pink flowers.In co-dominance, the dominant allele has as much effect on the phenotype of the organism as the recessive allele. Think red and white flowers now leading to red and white streaked flowers.
Why you called co-dominance when a person possess two different alleles at the same locus and both alleles are expressed in the phenotype?
Co-dominance is used to describe a situation where two different alleles at the same locus are both expressed in the phenotype of an individual. This results in a distinct phenotype that combines traits from both alleles, rather than one allele being dominant over the other. Examples include blood type AB in humans, where both A and B antigens are expressed on red blood cells.
What are the pair of alleles for a trait and how do they determine the expression of that trait?
Alleles are pairs of genes that determine a specific trait in an organism. Each parent contributes one allele, and the combination of alleles determines how the trait is expressed. If the alleles are the same (homozygous), the trait will be expressed in a certain way. If the alleles are different (heterozygous), one allele may be dominant and determine the trait's expression, while the other may be recessive and not expressed.
