Hey,
Friend,
When Mendel crossed true breeding tall plants with true breeding dwarf plants, the first progenies ( F1 Generation) Produced had only tall plants. In offsprings the tallness supressed the dwarfness. Mendel, therefore ,called traits such as tallness ( They appear in F1 generation ) dominant and dwarfness ( Which does not appear in F1 generation) as recessive.
Sexually reproducing inviduals have two copies of genes for each trait ( TT, Tt or tt) .If the copies are not identical ( Tt) , the trait gets expressed is called the dominant trait and the other is called the recessive trait.
Hope this will help you...!
