Question

Test cross in pea plant is:

• A. A cross between F2 tall plant and recessive parent.
• B. A cross between F2 dwarf plant and recessive parent.
• C. A cross between F2 tall plant with dominant parent.
• D. A cross between two F1 plants.

Hint:

Test crosses are fundamental tools in genetic analysis to infer the genetic composition of an organism.

Answer 1

The Correct Option is A

A test cross is used to determine the genotype of an organism showing a dominant phenotype.
In Mendelian experiments, the organism is crossed with a homozygous recessive parent.
For example, in a tall pea plant, this test reveals whether the tall plant is homozygous (TT) or heterozygous (Tt).
