Question

A true breeding plant is ______________

• A. one that is able to breed on its own.
• B. produced by cross pollination of different plants of same species.
• C. produced by self pollination of different plants of different species.
• D. a plant, when self-fertilized, always produce offspring with the same phenotype.

Answer 1

The correct option is D a plant, when self-fertilized, always produce offspring with the same phenotype.

A true-breeding plant variety is one that has undergone self-pollination generation after generation and has stable trait inheritance. It produces plants that are genetically identical for the specified traits.

A true-breeding plant can not be obtained by cross-pollination as two different genetic materials will be present in the offspring and it leads to unique characters instead of stabilising the same character.

Moreover, self-pollination between different plants of different species is not possible as stigma will reject the pollen.

Any plant is able to breed either via self-pollination or via cross-pollination with the help of some agents.
