REY [17]

The question is incomplete. The complete question is:

Question: If a horticulturist breeding gardenias succeeds in having a single plant with a particularly desirable set of traits, which of the following would be her most probable and efficient route to establishing a line of such plants?

A) Backtrack through her previous experiments to obtain another plant with the same traits.  

B) Breed this plant with another plant with much weaker traits

C) Clone the plant asexually to produce an identical one

D) Force the plant to self-pollinate to obtain an identical one.

Answer:

C) Clone the plant asexually to produce an identical one

Explanation:

Asexual reproduction is a mode of production of progeny from a single parent. It does not include the fusion of male and female gametes. Therefore, the progeny obtained from the asexual reproduction is genetically identical to the parent plant and is called a clone. One of the methods of asexual reproduction in plants includes vegetative propagation.

To maintain desirable traits in progeny, one must perform asexual reproduction in the single parent plant with such traits. The asexual reproduction would produce the progeny having all the desirable genetic traits as that of the parent plant.
