The recessive allele is still present but it is not manifested in any trait. For a recessive phenotype to be observed, an individual needs to have both copies of the recessive allele from both parents. What are dominant alleles? A dominant allele determines the expression of a specific trait ...
Alleles that are dominant are expressed whether there are one or two copies of the allele. Recessive alleles are expressed only in the absence of a...Become a member and unlock all Study Answers Start today. Try it now Create an account...
This is the most straightforward demonstration of dominant and recessive alleles. In pea plants, their flowers can be purple or white. The dominant trait is purple (P) and the recessive is white (p).Dominant Trait Examples Lesson Summary Register to view this lesson Are you a student or a ...
Dominance ingeneticscan be categorized into complete dominance,incomplete dominance, andcodominance. In complete dominance, the presence of a dominantalleleresults in the samephenotype, regardless of whether it is homozygous or heterozygous. In incomplete dominance, heterozygous individuals exhibit a distinc...
gene’s two alleles are located in the same region in two homologous chromosomes, one inherited from each parent. The alleles may bedominantorrecessive. Thedominant allele(definition:the allele that is expressed) masks the effect of therecessive allele(definition:the allele that is not expressed)...
Answer and Explanation:1 An allele is a gene variant. In diploid organisms, the DNA will contain two alleles for each gene. The combination of alleles determines the genotype... Learn more about this topic: Dominant & Recessive Alleles | Definition, Types & Examples ...
The traits of each parent are neither dominant or recessive. In a partial dominance relationship, between two alleles, a third phenotype is a result and is a combination of phenotypes of the two homozygotes; this is often referred to as an “intermediate form of inheritance.” The alleles do...

The dilution of the dominant allele with respect to the recessive allele is also termed incomplete dominance. There is a reduced ratio of dominant alleles. The variation of an organism’s traits or properties is largely influenced by incomplete dominance. ...
One is dominant, and the other is recessive. The combination of alleles inherited by an individual determines his or her phenotype, or the visible traits, such as hair color, eye color, or attached vs unattached ear lobes. So what is the difference between dominant and recessive alleles? A ...
