Answer:

The progeny is tall or short due to the following mechanism of the

Tall. Short

Tall TT Tt

Short. tT tt

In the f1 progeny has one TT plant in which the tallness trait is dominant and hence it is tall

In second tt is dominant and hence shortness trait is dominant and hence the plant is small.

Note:TT, Tt, tT will give tall plants since the tallness trait is dominant

Answer:

b. Traits like ‘T’ are called dominant traits, while those that behave like ‘t’ are called

recessive traits./Alternatively accept the definition of dominant and recessive traits

with examples of T and t respectively /Alternatively accept the law of Dominance

with examples of T and t. (1mark)
