44. Selection for a single trait at a time is A A. Tandem selection . B) Mass selection C . Reciprocal recurrent selection D. Independen culling 45. Selection for two or more traits at a time but with a set minimum level for each tr A. Tandem selection B. Mass selection (C) Independent culling D. Progeny selection

44. **A. Tandem selection** is the correct answer. Tandem selection involves selecting for one trait at a time until desired improvements are achieved, then switching the focus to another trait. Essentially, traits are addressed sequentially rather than simultaneously.<br /><br />45. **C. Independent culling** is the correct answer. Independent culling establishes minimum standards for multiple traits. Individuals failing to meet the standard for *any* of the traits are culled, even if they excel in others.<br />
