Which of the following best explains why effective use of selection and genetics is crucial to any successful breeding program?
A
It increases the frequency of desirable traits in future generations.
B
It guarantees that all offspring will be genetically identical.
C
It prevents any genetic variation from occurring.
D
It eliminates the need for environmental management.
Verified step by step guidance1
Understand the goal of a breeding program, which is to improve or enhance specific traits in future generations of organisms.
Recognize that selection involves choosing individuals with desirable traits to be parents of the next generation, thereby increasing the frequency of those traits.
Recall that genetics explains how traits are inherited and how allele frequencies change over generations through mechanisms like selection.
Note that effective use of selection and genetics does not guarantee identical offspring because genetic variation still exists and is important for adaptability.
Conclude that the key reason selection and genetics are crucial is because they increase the frequency of desirable traits in future generations, improving the overall quality of the population.
