What is the primary goal of marker-assisted selection (MAS) in plant breeding?
-
To identify and select plants with desirable traits
-
To increase the genetic diversity of a population
-
To create genetically modified organisms (GMOs)
-
To study the evolution of plant species
A
Correct answer
Explanation
The primary goal of MAS is to identify and select plants that possess desirable traits, such as resistance to pests or diseases, improved yield, or enhanced nutritional value.
What are genetic markers and how are they used in MAS?
