Question

Gregor Mendel crossed homozygous tall plants (TT) with homozygous short plants (tt). All the resulting offspring were tall. From these results, what conclusion did Mendel draw?

Answer 1

"T" was a dominate trait.

Answer 2

Mendel can conclude that T is dominant over t.

Step-by-step explanation:

Mendel is known as the father of genetics. He works on the plant Pisum sativum and explain the various laws of genetics.

When Mendel crossed the tall homozygous plant with short plants ( TT × tt). All plants are tall (Tt). This explains that 'T' gene is dominant over 't'. T doesnot allow the expression of the 't' gene and plants are tall. This gives the law of dominance. According to this law, in pair of contrasting trait, one trait can hides the expression of other trait. The trait that can express itself is known as dominant trait and and the trait that cannot express itself is known as recessive trait.
