Dominant allele. Dominant Allele Definition. A dominant allele is a variation of a gene that will produce a certain phenotype, even in the presence of other alleles. A dominant allele typically encodes for a function ing protein. [>>>] dominant allele. the allele that is express ed when present in the heterozygote. Source: Jenkins, John B. 1990.
dominant allele – an allele that produces the same phenotype whether its paired allele is identical or different dominant allele , allelomorph – (genetics) either of a pair (or series) of alternative forms of a gene that can occupy the same locus on a particular chromosome and that control the same character; some alleles are dominant over others, Alleles can be either dominant or recessive. Dominant alleles show their effect even if the individual only has one copy of the allele (also known as being heterozygous). For example, the allele for brown eyes is dominant, therefore you only need one copy of the ‘brown eye’ allele to have brown eyes (although, with two copies you will still have brown eyes).
Dominant allele is the allele that determines the phenotypical features apparent in homozygous or heterozygous genotype s. In Genetics, the dominant allele is represented in uppercase (A), and its recessive allele is written in lowercase (a). [>>>] Dominant allele any allele that is always expressed in the phenotype of an organism.
6/4/2020 · A dominant allele is the one that expresses itself by overriding the other allele. A recessive allele would be the one that that gets overridden in the presence of a dominant allele. Genetic expression is dependent on such alleles. They may be more than two alleles for a given gene.
