What term describes the breeding process that selects for desired traits while eliminating undesired ones?

• A. Natural selection
• B. Artificial selection
• C. Genetic drift
• D. Gene expression

Answer: (B)

The term that describes the breeding process selecting for desired traits while eliminating undesired ones is artificial selection. This process involves humans actively choosing which individuals will reproduce based on specific characteristics they wish to cultivate, such as size, color, or behavior. This method is widely used in agriculture and animal husbandry, where traits are selectively enhanced over generations to produce desired results.

In contrast, natural selection is a process driven by environmental pressures where individuals with traits that enhance survival and reproduction are more likely to pass on their genes to the next generation. Genetic drift refers to random changes in allele frequencies in a population, particularly in small populations, and is not influenced by selection for traits. Gene expression involves the way genes are turned on or off in cells and does not pertain directly to the breeding process or selection.
