- Dominant traits are always expressed when the connected allele is dominant, even if only one copy of the dominant trait exists. Recessive traits are expressed only if both the connected alleles are recessive.
- When an allele is dominant, the characteristic it is connected to will be expressed in an individual. When an allele is recessive, the characteristic it is connected to is less likely to be expressed. Recessive traits only manifest when both alleles are recessive in an individual.
- In genetic terms, a dominant trait is one that is phenotypically expressed in heterozygotes). A dominant trait is opposed to a recessive traitwhich is expressed only when two copies of the gene are present.A recessive trait is the weak, unexpressed trait of a dichotomous pair of alleles (dominant-recessive) that has no effect in the phenotype of heterozygous individuals.
