Difference between dominant and recessive trait

:white_check_mark:Difference Between Dominant and Recessive Traits

:arrow_right: Expression in an Individual
:heavy_minus_sign:Dominant traits are always expressed when the connected allele is dominant, even if only one copy exists
:heavy_minus_sign:Recessive traits are expressed only if both the connected alleles are recessive. If one of the alleles is dominant, then the associated characteristic is less likely to manifest.

:arrow_right: Representation in Literature
:heavy_minus_sign:Dominant allele is denoted by a capital letter
:heavy_minus_sign:Recessive allele is denoted by a small letter
