If one allele is not dominant over the other it would mean the alleles are the same so that organism would be a mutant.

Allele that is always expressed if present?
An allele that is always expressed when it is present is the dominant allele.
Why do we call some alleles dominant?
because it dominates the phenotype
What happens to the recessive allele in a heterozygous offspring?
The recessive allele is present, but not shown in complete dominance. This is because the dominant allele is completely dominant over the recessive allele, therefore it is shown, while the recessive allele is hidden.
What does The presence of an allele for purple flowers will mask the presence of an allele for white flowers mean?
Gene responsible for purple color is dominant over white color.
Is when one allele completely masks another?
when one allele is completely dominant over another allele, then it masks the expression of the second allele so the allele that masks the effect is called dominant allele and the allele whos effect is masked is called recessive allele
What is a dominent allele?
A dominant allele is an allele that can take over a recessive allele, so if you have a dominant allele and a recessive allele, then the offspring will most likely have a dominant allele over a recessive allele. The dominant allele is expressed over the recessive allele.
Allele that is always expressed if present?
An allele that is always expressed when it is present is the dominant allele.
Why do we call some alleles dominant?
because it dominates the phenotype
An allele that is dominated or cover up by another allele is called what?
It should be a dominant allele--a dominant allele's trait will be expressed over the recessive allele's trait.
How does an allele trait in an organism?
An allele causes a trait by either being dominant orrecessive or example, allele A will occur over allele a because it is dominant.
What happens to the recessive allele in a heterozygous offspring?
The recessive allele is present, but not shown in complete dominance. This is because the dominant allele is completely dominant over the recessive allele, therefore it is shown, while the recessive allele is hidden.
What is dominant the X or the Y?
An allele on either X or Y could be dominant over the allele on the other chromosome, but it is more common for the allele on the X to be dominant, because the Y chromosome is much smaller than the X and contains fewer genes. In many cases, there is no allele for a particular gene on the Y chromosome; so whatever allele is on the Y will be dominant.
What does The presence of an allele for purple flowers will mask the presence of an allele for white flowers mean?
Gene responsible for purple color is dominant over white color.
Is when one allele completely masks another?
when one allele is completely dominant over another allele, then it masks the expression of the second allele so the allele that masks the effect is called dominant allele and the allele whos effect is masked is called recessive allele
What is the best term to describe the allele that is expressed over all other alleles of the same trait?
Dominant; genetics.
What is the difference between dominant and recessive alleles for specific traits?
Dominant is an allele that will always be expressed in a heterozygous individual. Recessive on other hand are traits that will only be expressed in a homozygous condition. Organisms receive one allele for each trait from each parent, thus you have two alleles for each trait.
When two alleles for a trait are different?
If you have a heterozygous genotype (X, x), then you would take on the phenotype of the dominant allele. There are some instances where neither trait is fully dominant over the other. This is called incomplete dominance, and usually results in a blending effect of the two traits.
