Question

HOW DO MENDEL'S EXPERIMENT SHOW THE

TRAITS MAY BE DOMINANT OR RECESSIVE?​

Answer 1

Answer:

) 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 was dominant over the dwarf trait. This shows that traits may be dominant or recessive

Answer 2

Explanation:

Mendel conducted the experiments using Pisum sativum or pea plant.

He selected homozygous tall (TT) and dwarf (tt) pea plants.

He crossed the tall pea plant with the dwarf pea plant.

It was observed that the F

1

generation are all tall plants.

Thus, it was concluded that the gene causing tallness is dominant while the gene causing dwarfness is recessive.

The trait expressing itself in the hybrid is the dominant one.

This experiment proves Mendel’s first law of inheritance.

It states that when a pair of contrasting factors is brought in a hybrid, one factor inhibits the appearance of the other, one which inhibits is the dominant one and which is inhibited is recessive.
