How do mendal's experimentioned show the tRait may be dominent or recessive

Answer 1

In Mendel's experiment all the F1 generation were tall and no dwarf plant was seen while in F2 generation the dwarf plant reappeared. The experiment showed that a single copy of ‘T’ is enough to make the plant tall, while both copies have to be ‘t’ for the plant to be short. Traits like ‘T’ are called dominant traits, while those that behave like ‘t’ are called recessive traits. Thus Mendel's experiment showed that the traits can be dominant or recessive.
