In a population natural selection acts on

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.

Evolution by Natural Selection

WebJan 11, 2024 · Natural selection acts on the phenotype (the traits or characteristics) of an individual. On the other hand, natural selection does not act on the underlying genotype (the genetic makeup) of an individual. For many traits, the homozygous genotype, AA, for example, has the same phenotype as the heterozygous Aa genotype. Natural selection is the differential survival and reproduction of individuals due to differences in phenotype. It is a key mechanism of evolution, the change in the heritable traits characteristic of a population over generations. Charles Darwin popularised the term "natural selection", contrasting it with artificial selection, which is intentional, whereas natural selection is not.

WebJun 2, 2024 · Natural Selection Acts on Individuals, not Alleles Natural selection is also limited because it acts on the phenotypes of individuals, not alleles. Some alleles may be more likely to be passed on with alleles that confer a beneficial phenotype because of their physical proximity on the chromosomes. WebNatural selection is the simple result of variation, differential reproduction, and heredity — it is mindless and mechanistic. It has no goals; it’s not striving to produce “progress” or a …
