Question

how do Mendel's experiments show that traits may be dominant or recessive? Explain diagramatically.

Answer 1

(a) Mendel demonstrated that traits can be either dominant or recessivethrough 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. Thisshows that traits may be dominant or recessive

Answer 2

Mendel conducted experiments on garden pea plant selecting several visible contrasting character. He selected and crossed the pure bred tall pea plant having the genotype TT with a pure bred dwarf pea plant having the genotype tt. F1 generation consists of only tall plants having the genotype Tt. the expressed allele T for the tallness is dominant over the unexpressed allele t dwarfness . hence the trait of tallness is dominant character while the trait of dwarfness is recessive
