Question:

When does a farmer prefer asexual or sexual methods of reproduction for crops production? [Pg. No. 208]

Answer: Verified

A farmer prefers asexual reproduction when rapid multiplication of plants with desirable traits is needed. It produces offspring identical to the parent plant and helps preserve useful characteristics. Methods such as cuttings, grafting and tissue culture are commonly used.
A farmer prefers sexual reproduction when new varieties of crops with improved traits, such as higher yield, disease resistance or better adaptability, are required. Sexual reproduction produces variation among offspring, which can be beneficial for crop improvement.
