The allele that is present and can express a trait in an organism is known as the dominant allele. If an organism has at least one copy of the dominant allele, the associated trait will typically be observable. In contrast, a recessive allele will only manifest if two copies are present. Therefore, the presence of the dominant allele determines the appearance of the trait.
What else can I help you with?
If an allele for a particular trait is NOT expressed at all when another allele for the trait is present the allele is .?
The allele not expressed would be recessive whilst the other is dominant. This would be the case in a heterozygous genotype. Hope this helps
What does a dominant allele always do?
A dominant allele expresses its trait in an individual when present, masking the effect of a recessive allele. This means that if an individual has at least one copy of a dominant allele, the associated trait will be displayed.
Does a dominant trait appear in the first generation?
Yes, a dominant trait will appear in the first generation if one of the parents carries the dominant allele. Dominant traits only need one copy of the allele to be expressed.
Two alleles for a certain trait are passed to an individual. what terms refers to the trait that will show up in the individual?
The allele that is expressed in an individual is referred to as the dominant allele. This allele masks the effect of the recessive allele when present.
If an allele for a particular trait is not expressed at all when another allele for the trait is present the allele is?
The allele not expressed would be recessive whilst the other is dominant. This would be the case in a heterozygous genotype. Hope this helps
What is trait called that appear only when both alleles are present?
A trait that appears only when both alleles are present is called a recessive trait. In this case, the trait is masked when the dominant allele is present, but becomes visible when two copies of the recessive allele are inherited.
What allele whose trait only shows up when no dominant allele is present?
Such a trait is called a recessive trait.
Which is the dominant allele?
The dominant allele is the trait that shows up in the organism when the allele is present
The allele for the trait that does not appear in a heterozygous individual is?
recessive
The allele for the sickle cell trait is what with the normal allele?
The allele for the sickle cell trait is codominant with the normal allele. This means that in individuals with both alleles present, both traits are expressed.
If an allele for a particular trait is NOT expressed at all when another allele for the trait is present the allele is .?
The allele not expressed would be recessive whilst the other is dominant. This would be the case in a heterozygous genotype. Hope this helps

Does a dominant trait appear in the first generation?
Yes, a dominant trait will appear in the first generation if one of the parents carries the dominant allele. Dominant traits only need one copy of the allele to be expressed.
Not expressed when the dominant form of a trait is present?
Recessive traits are not expressed when the dominant form is present. This is because the dominant allele masks the expression of the recessive allele in the heterozygous condition. Only when an individual has two copies of the recessive allele will the recessive trait be expressed.
Two alleles for a certain trait are passed to an individual. what terms refers to the trait that will show up in the individual?
The allele that is expressed in an individual is referred to as the dominant allele. This allele masks the effect of the recessive allele when present.
What does resscessive mean?
a resscessive allele, is hidden when the dominant trait is present
If an allele for a particular trait is not expressed at all when another allele for the trait is present the allele is?
The allele not expressed would be recessive whilst the other is dominant. This would be the case in a heterozygous genotype. Hope this helps
