Which of the following statements about natural selection is true? A. Natural selection favors individuals that reproduce more than others. B. Natural selection occurs in opposition to evolution. C. Natural selection can be used by farmers to generate organisms with desirable traits. D. Natural selection is a process whereby genes are selectedAll of the following are true of natural selection,EXCEPT A) it works best in genetically uniform populations. B) it results in populations better suited to their environment than their predecessors. C) it is the process by which evolution occurs. D) it results in some individuals surviving better and reproducing more than others.answer. answered. Which of the following is true about natural selection? A.natural selection acts upon individual organisms by changing their genetic code through a process known as gene flow. b.natural selection acts upon sexually reproducing populations that lack genetic variation among individual organisms.Natural selection creates new diversity. Natural selection brings about a change in an individual. Natural selection increases genetic diversity. Natural selection makes a species better. Natural...12) Which of the following is a true statement concerning genetic variation? A) It is created by the direct action of natural selection. B) It arises in response to changes in the environment. C) It must be present in a population before natural selection can act upon the population.

What is true of natural selection? A) Natural selection is a random process. B) Natural selection creates beneficial mutations. C) The only way to eliminate harmful mutations is through natural selection. D) Mutations occur at random; natural selection can preserve and distribute beneficial mutations.Darwin proposed the theory of natural selection to explain the process of evolution. According to Darwin's theory of natural selection, all organisms have the potential to reproduce limitlessly irrespective of the fact that each species maintain a constant density over time.Is it Natural Selection? 1. For each of the following scenarios, use this checklist to decide if it is natural selection or not. Natural Selection Checklist Change over time Has the frequency of the trait in the population changed over time? Yes or No Evidence: Variability Does the trait vary among individuals in the population?It is necessary for natural selection. It exists in almost all populations. It is caused by mutations and sexual reproduction. All of the choices are correct.

which of the following is true about natural selection? A

Which of the following, about natural selection, is false? A. Differential survival of individuals in a population based on the traits that they possess is part of natural selection. B. Differentia...A - Natural selection can only happen if the survival of one group of organisms is somehow favoured and they survive better than another group. If one group is favoured it is usually because there is genetic variation behind these differences. It is however possible for selection to occur because of LEARNT behaviour rather than genetic differences.-Natural selection favors individuals that reproduce more than others. -Natural selection occurs in opposition to evolution -Natural selection is a process whereby genes are selected randomly for preservation in the next generation -Natural selection can be used by farmers to generate organisms with desirable traitsAfter this introduction of natural selection, Darwin elaborated on the subject with his theory of evolution and his book, On the Origin of Species, published in 1859.His work with Darwin's finches and his ideas on survival of the fittest explained the mechanism of natural selection and how it could lead to a proliferation of many different kinds of organisms.Which statement is NOT true about natural selection? A. Directional selection occurs when one extreme phenotype is favored over another different extreme phenotype. B. Stabilizing selection favors an intermediate phenotype over either of the extreme phenotypes. C. Disruptive selection favors both of the extreme phenotypes over the intermediate
