What are dominant traits?

Dominant traits are characteristics that are expressed in an organism even when only one copy of the corresponding allele is present.

In a pair of alleles, the dominant allele masks or overrides the effect of the recessive allele. This means that if an individual inherits one dominant allele and one recessive allele for a trait, the dominant trait will be visible in the phenotype.

Dominant traits are usually represented by uppercase letters, for example, “T” for tallness.

An example of a dominant trait is brown eye color in humans, which can be expressed even if only one dominant allele is inherited.

Dominant traits play a key role in inheritance patterns and help explain how certain characteristics appear more frequently in offspring.
