Consider the following experiment: True-breeding tall pea plants are cut short before being pollinated to determine if there is an effect on the offspring. Which explanation for trait inheritance is this testing?

The question is incomplete. The complete question is:

Consider the following experiment: True-breeding tall pea plants are cut short before being pollinated to determine if there is an affect on the offspring. Which explanation for trait inheritance is this testing?

A Blended inheritance

B Gene theory

C An organism's experiences are passed to their offspring

D None of the above

Answer:

Gene theory

Explanation:

Gene theory is the proposition that genes are the basic units in which characteristics or traits are passed from one generation to another generation. Genes themselves, as derived from Mendelian theory are the basic units of heredity. The gene theory provides a basis for understanding how genes enable parents to transmit traits to next generation.

The experiment aims to discover weather the gene for tallness is still passed on to the offspring irrespective of the experience of the parents.
