Question

how do mendel's experiments show that traits may be dominant or recessive?

Answer 1

Mendel demonstrated that traits can be either dominant or recessive through his monohybrid cross. He crossed true-breeding tall (TT) and dwarf (tt) pea plants. ... They appeared tall only because the tall trait wasdominant over the dwarf trait. This shows that traits may be dominant or recessive.

Hope it will help you.
if you are satisfied with the answer then mark my answer as brainlist answer please

Answer 2

Here's ur answer dear,
When Mendel did cross pollination with pure pea plants ( TT ✖ tt ) ,he got all the plants tall in F1 generation ( Tt,Tt,Tt,and Tt).And when Mendel did self pollination with plants of F1 generation, he got 3 tall plants and 1 dwarf plant, which were in 3:1 ratio. So.,Mendel call these TALL characters as DOMINANT, and DWARF character as RECESSIVE traits.
