I don't know how to explane  this but my teacher thought me if it's Dominant it always Recessive in another way of sometimes.

Answer 2

The frequency of expression of dominant and recessive traits can be Dominant traits = always / Recessive = sometimes.

According to the question if there is self cross TT×tt then there is TT, Tt, Tt and tt, which means there is a 75% possibility of dominant trait and 25% recessive.

How Dominant and Recessive traits are different from each other?

Dominant traits are always described when the related 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.
