This depends on the type of dominance relationship. You can have true dominance, in which case if the allele pair contains a dominant allele, the dominant trait will be expressed. In this case the recessive trait will only be exhibited if both alleles are recessive.
A second case is that of codominance. In this case, two alleles are codominant, so if you have one of each, both traits will be expressed.
A third case is that of incomplete dominance. In this case, if you have a dominant and a recessive allele, you will get a trait which is a mixture of both traits. A good example is when you breed a red flower and a blue flower and get a purple flower as progeny.
Other things, like dominance series, also exist. However this information should answer your original question.
In a dominance-recessive interaction, one allele (dominant) masks the expression of the other allele (recessive) in a heterozygous individual. The dominant allele is expressed phenotypically, while the recessive allele's traits are not visible. This interaction occurs at the level of gene expression and influences the observable traits or phenotype of an organism.

What is the term for an allele that is not expressed in the phenotype of a heterozygous individual?
incomplete dominance source: PH Bio textbook
What does the principle of dominance state?
Basically, it states there are two forms of a gene called alleles, heterozygous in this case, and one allele masks the expression of the other allele. This is simplified, as it can get complex with co-dominance and partial dominance.
What does the law of dominance state?
"What does the law of dominance state?"Mendel's law of dominance states that if you have a pair of genes then the one that shows up in the offspring is most likely the dominant gene because the dominant is passed along more often than the recessive.Read more: Explain_Mendel's_Law_of_Dominance
What type of allele masks the expression of the recessive allele?
Two recessive alleles can not take over a dominant allele because there are only two alleles in a pair. This can only happen if there is a mutation because the dominant always takes over the recessive.
What kind of gene pair that consists of a dominant allele and a recessive allele?
Heterozygous. Nice job your getting your life science homework answers on answers.com-lol
Principle states that one factor in a pair may prevent the other factor in the pair from being expressed?
This principle is called the principle of dominance. It explains that in a pair of alleles, the dominant allele will be expressed over the recessive allele. So, the dominant factor will prevent the recessive factor from being expressed in the phenotype.

What is the weaker allele in a pair of genes?
Recessive Allele
The weaker of two alleles in a pair that is often masked by the dominant allele?
The recessive allele.
What is a gene pair that consists of a dominent allele and a recessive allele?
Heterozygous dominant pair.
What is the name of the gene pair that consist of a dominant allele and recessive allele?
The name of the gene pair that consists of a dominant and recessive allele, i.e. (Xx) will be a heterozygous allele. In this situation, the characteristics of the dominant characteristic will mask that of the recessive allele. People have have a heterozygous genotype may be carriers for diseases that reside on the recessive allele.
Gene pairs consists of two dominant alleles or two recessive alleles?
Actually, gene pairs can consist of two dominant alleles, two recessive alleles, or one dominant and one recessive allele. The combination of alleles in a gene pair determines the specific trait expressed by an individual.
Which form of gene pair is expressed when both dominant and recessive are present?
In a situation where both a dominant and recessive allele are present in a gene pair, the dominant allele will be expressed phenotypically. The presence of a dominant allele overrides the expression of the recessive allele.
What is a complete dominance?
Complete dominance is a genetic phenomenon where one allele in a gene pair completely masks the expression of the other allele. In this case, the dominant allele will always be expressed in the phenotype of the organism, while the recessive allele will be hidden.
What type dominance do pea plants show?
Pea plants exhibit complete dominance, which occurs when one allele in a pair masks the effect of the other allele completely. This means that in a heterozygous individual, only the dominant allele is expressed phenotypically.
What is called when you have a pair of genes that cnsits of a dominant allele and a recessive allele?
heterozygous
