A genetic characteristic that exhibits its observable traits when only one copy of the gene is present is known as a dominant trait. Dominant genes override the presence of recessive genes, leading to the expression of the dominant trait. It is noteworthy that dominant traits can be inherited from a single parent.
A hereditary trait (a feature or condition) that becomes apparent when only one copy of the gene responsible for that trait exists, unlike a recessive trait, which only emerges when two copies of the corresponding gene are present. Dominant genes consistently obscure the existence of recessive genes, and dominant traits can be inherited from just one parent.
