Thus, allele R is dominant over allele r, and allele r is recessive to allele R. Dominance is not inherent to an allele or its traits (phenotype). It is a ...
The allele that is not expressed in the phenotype when two different alleles are present in the cells of an organism. The aspect of a characteristic ...
A type of allele that when present on its own will not affect the individual. Two copies of the allele need to be present for the phenotype to be expressed.
Only one of each pair of genes has to be present for the animal to show the dominant trait but both alleles of a pair must be recessive for the trait to be ...
When a trait is recessive, an individual must have two copies of a recessive allele to express the trait. Recessive alleles are denoted by a lowercase letter (a ...
8 天前 — A recessive allele does not produce a trait at all when only one copy is present. This contrasts to a dominant trait, which requires that only ...
2021年7月21日 — Different versions of a gene are called alleles. Alleles are described as either dominant or recessive depending on their associated traits.
For a recessive allele to produce a recessive phenotype, the individual must have two copies, one from each parent. An individual with one dominant and one ...
