When allele pairs are the same, they are homozygous. Dominant negative mutations (also called antimorphic mutations) have an altered gene product that acts antagonistically to the wild-type allele. What are synonyms for dominant allele? The dominant allele is expressed and the recessive allele is masked. Dominant versus Recessive comparison chart;

lele (ă-lēl'), Avoid the mispronunciations al-ĕl' and al'ēl.

The genetic code behind a trait is known as the genotype. Recessive Allele Definition. 1 synonym for dominant allele: dominant. When a dominant allele is paired with a recessive allele, the dominant allele determines the characteristic. The allele that masks the other is said to be dominant to the latter, and the alternative allele is said to be recessive to the former. dominant-allele | definition: an allele that produces the same phenotype whether its paired allele is identical or different | synonyms: allelomorph, allele, dominant| antonyms: subordinate, inferior, … In a heterozygote the effect of one allele may completely ‘mask’ the other. (Persons with neither are type O.) Dominant refers to the relationship between two versions of a gene. dominant allele : Definition: Search for: Biology Glossary search by EverythingBio.com An allele that expresses its phenotypic effect even when heterozygous with a recessive allele; thus if A is dominant over a, then AA and Aa have the same phenotype. A recessive. Dominance. That is, the phenotype produced by the two alleles in heterozygous combination is identical to that produced by one of the two homozygous genotypes. Dominant or recessive alleles. 1 synonym for dominant allele: dominant. If the alleles of a gene are different, one allele will be expressed; it is the dominant gene. Often when these are paired and compared, one gene (the dominant) will be found to effectively shut out the instructions from the other, recessive gene. This is known as complete genetic dominance. Hybrid. Different versions of a gene, of which code for different versions of a characteristic. An example is the human ABO blood group system; persons with type AB blood have one allele for A and one for B. Filial Generation. Define recessive allele. These mutations usually result in an altered molecular function (often inactive) and are characterized by a dominant or semi-dominant phenotype. A recessive allele is a variety of genetic code that does not create a phenotype if a dominant allele is present. Recessive alleles are represented by a lower case letter, for example, a.

A "dominant" allele is dominant to a particular allele of the same gene that can be inferred from the context, but it may be recessive to a third allele, and codominant to a fourth.

dominant allele : Definition: Search for: Biology Glossary search by EverythingBio.com An allele that expresses its phenotypic effect even when heterozygous with a recessive allele; thus if A is dominant over a, then AA and Aa have the same phenotype. Antonyms for dominant allele. Alleles may be either dominant or recessive: A dominant allele is always expressed, even if the individual only has one copy of it.

An organism that has two different alleles for a trait; an organism that is heterozygous for a particular trait. In a dominant/recessive relationship between two alleles, the recessive allele’s effects are masked by the more dramatic effects of the dominant allele. Some alleles are dominant to other forums of a gene and will always be expressed. An example is the human ABO blood group system; persons with type AB blood have one allele for A and one for B. Individuals receive two versions of each gene, known as alleles, from each parent.
