Question

Greatest genetic diversity of plants is found in

• A. Central America
• B. Homelands
• C. South America
• D. India

Answer 1

The correct option is B Homelands

Sexual reproduction is critical for maintaining genetic diversity within a species because it combines the parents genetic material, resulting in offspring with unique genetic blueprints different from either parent. Genetic diversity is important for two reasons. First of all, when a population of an organism contains a large gene poolthat is, if the genetic blueprints of individuals in the population vary significantly the group has a greater chance of surviving and flourishing than a population with limited genetic variability. Second, genetic diversity also reduces the incidence of unfavorable inherited traits. The home lands of our food crops are vital geographic regions where the greatest genetic diversity for each species can be found. Because in homelands there are more chances of sexual reproduction with in the species which is critical for maintaining genetic diversity. Thus, option B is correct. Greatest genetic diversity of plants is not found in Central America, India and South America. Thus, other options are wrong.
