Answer: A trait that masks another trait is called dominant trait.
A trait is a characteristic or a morphological form that is expressed in an organism. There can be two different types of traits according to Mendelian genetics that is Dominant and Recessive trait. They are expressed due to two different forms of a gene that is called allele.
A dominant allele usually represented by capital letter like T for tall, corresponds to dominant trait and this masks the expression of recessive trait. Example- Tall plant height.
On the other hand, recessive allele is represented by small letter like t for dwarf and corresponds to recessive trait. This trait does not express in the presence of dominant allele.
Example- Dwarf plant height.
