2. 
Choose the correct option:

I) In the case of the character of height, T is used for the Tall trait, and d is used for the dwarf trait.

II) In true-breeding, tall or dwarf pea variety the allelic pair of genes for height are homozygous and heterozygous respectively.

III) TT and tt are called phenotypes of the plant.

IV) The descriptive terms tall and dwarf are the genotypes.

3.

________ contain information that is required to express a particular trait in an organism.

7. 
Choose the correct option:

Assertion:  All the test crosses are backcrosses.
Reason: In the test cross F1 generation having dominant phenotype is crossed to the parent plant having recessive phenotype.
