this could be answered as we inherit the characteristics of both mother and father but only the characters that are dominating are expressed but the rest are there which might b expressed later.

but how did mendel explain this????
well by growing over pea plants and observing them for over long period of time of time he did so. For this he took the different pea plants crossed it with one another, then with the progeny and so on and then noted the observation on formulated the law of inheritance.

When Mendel crossed pure tall (TT) pea plants with a pure dwarf (tt) pea plants, in the F1 generation he found that all pea plants were tall (Tt). There were no dwarf plants produced in an F1 generation. When he self-pollinated these F1 plants, in the F2 generation he obtained tall and dwarf plants in the ratio 3:1. Thus as three-fourths of the plant in an F2 generation are tall and one-fourth is dwarf so tall is a dominant trait whereas dwarf is a recessive trait [ which expressed itself only in homozygous condition]. The dwarf trait was inherited in an F1 generation but it does not get expressed, it remains suppressed in presence of dominant trait tall.
