WebNatural selection acts on populations through a specific trait. Which statement must be true about that trait? answer choices The trait is resistant to mutations. The trait is passed on genetically to the next generation. Most forms of the trait have the same impact on survival. The trait is the same for all organisms. Question 4 30 seconds Q. WebJul 17, 2024 · Natural selection only acts on the population’s heritable traits: selecting for beneficial alleles and thus increasing their frequency in the population, while selecting against deleterious alleles and thereby decreasing their frequency—a process known as adaptive evolution.
