Natural selection - Wikipedia

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. WebBy definition, natural selection is a function of populations. It is a process involving populations over the course of time, not determined by only one individual. We are … WebA. Natural Selection occurs because some alleles confer higher fitness, whereas genetic drift occurs because of sampling error. B.

WebOct 21, 2015 · Natural selection is one of the processes that drives evolution by selecting individuals best adapted to the current environment. Explanation: Natural selection is based on three facts: There is natural variation within a population. There is differential production. These variations are heritable. (The heritable units are genes .) WebNatural selection is a random process. Natural selection acts on phenotypes that are controlled by genes.

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. WebNatural selection acts on the phenotype, the characteristics of the organism which actually interact with the environment, but the genetic (heritable) basis of any phenotype that gives that phenotype a reproductive advantage may become more common in a population.
