Question

✌️law of dominance✌️​​

Answer 1

Answer:

So, Mendel takes two pea plants: One short pea plant (thus having genes “tt” for expressing height) and one tall pea plant ( Having a genes “TT” which express or determine its height.)

Then he bred them by pollinating the flower of one monohybrid short pea plant with pollen of monohybrid tall pea plant. However, when he planted these seeds after harvesting, he found that all of the offspring plants were tall. Why was this so?

We all know that in sex gametes, genes break up and one of them forms a pair with an allele from the other cell. For pea plants, the two sets of gametes were TT and tt. Hence, during meiosis, the only possible combinations is Tt.

Answer 2

The law of dominance includes the following :-

• The characters are controlled by completely discrete units called "factors".

• Factors occur in pairs.

• In a pair where two characters are not similar to each other, one of the two characters in the pair dominates the other character. The character which dominates is know as the dominant character and the character which gets dominated is known as the recessive character.
