Explain why it is easier for a stem cell to become cancerous that a fully differentiated cell (brain cell) to become cancerous. A condition necessary for evolution to occur is that there must be genetic variation among the excess offspring produced. both A and C The most "fit" genotypes and phenotypes can be selected from the genetic variation that exists in the population. A heterozygote is an individual with a different paternal and maternal allele at a particular locus. _____ is (are) the ultimate source of new variation in a population. One of the most important factors of the development of a new species is the geographical isolation. There are multiple sources of genetic variation, including mutation and genetic recombination. (5) 10. which of the following processes is the ultimate source of the genetic variation that serves as raw material for evolution. Sex can introduce new gene combinations into a population. Mutations are likely to be rare and most mutations are neutral or deleterious, but in some instances, the new alleles can be favored by natural selection. Furthermore, because mutation is the ultimate source of all genetic variation, clarifying why mutation rates vary is crucial for understanding all areas of biology. Evolution leads to adaptation. The most important requirement for the evolution is variation. Related Questions: In how many steps is ATP utilised in glycolysis The mutation is the ultimate source of genetic variation, but mechanisms such as sexual reproduction and genetic drift contribute to it as well.

New questions in Social Sciences. Microevolution: The agents of change 1. synonymous mutations but not only and soma mutations) do not bring up any the underlying genetic variance of phenotypic traits. Organisms evolve and develop adaptations in order to survive in their environments. Here we have sexual reproduction, mutation, genetic drift and natural selection. This supports which of the following: There is variation in a population Some variation is heritable Not all that are born will survive Mutation is the ultimate source of all variation Correct! Genetic shuffling is a … The strength and direction of selection depends on the environment. The cause of evolution, really speaking, comes from the germinal variation which is inheritable. The ultimate source of organic evolution is the mutation. A. Fertilization. 9. Assume a mutation resulting in a novel allele occurs in a gene of one individual in a population of 500 diploid individuals. However, they usually occur at very low frequency. The ultimate source of variation in population for organic evolution 1 See answer muzzu8086 is waiting for your help. There are several types of mutations, both at the gene-level and the chromosome-level. Also Know, what is the ultimate source of all variation in and among populations? Yes 4. Random mutations are the ultimate source of genetic variation. Mutations in genes can have no effect, alter the product of a gene, or prevent the gene from functioning properly or completely. The ultimate source of allelic variation is: (1) Recombination (2) Natural selection (3) Mutation (4) Drift. Favorite Answer Mutations are very strong contributors to genetic variation within a population, but independent assortment and dna recombination during sexual reproduction can … D. All of the above. @5. asked Sep 9, 2016 in Biology & Microbiology by Cleopold. From this perspective, mutation is a "good" thing. Answer. Q12: Doubts . Genetic drift: changes to allele frequencies based on chance 5. What kind of mutation is likely involved in generating new variation? Sexual reproduction: Recombination of genes, mate choice 4. The allele does not affect the fitness of the individual carrying the mutation. So the automated source off off variation is mutation. So let's start with sexual reproduction. The modern synthesis refers to the combination of modern genetics and Darwinism. Website not working properly (1) (2) (3) (4) Variation in a population often results from natural selection, random genetic drift, emigration, or mutation. Mutation can result in many different types of change in sequences. It generates the alleles that are required for a population to adapt to a particular habitat. Ultimate source of variation is MUTATION and nothing else. Without variation there could be no evolution, so mutations are of great importance to evolution. C. Mutation. Explanation: No explanation available. What is the ultimate source of all new genetic variation? Sexual Reproduction b.) The external factors may be light, heat, cold, food etc. Gene mutations provide new alleles, making these mutations the ultimate source of variation. B. Gene flow: Migration, movement and hybridization Macroevolution: the concept 1. Genetic variation can refer to differences between individuals or to differences between populations. Light (Points : 4) Environmental change Mutations Selective breeding Random chance Sexual Reproduction 9. Be the first to write the explanation for this question by commenting below. The ultimate source of all new genetic variation is: a) mutation. Mutation c.) Natural Selection d.) Genetic Drift 1. Genetic variation is the difference in DNA among individuals or the differences between populations. garvit28 garvit28 DNA copying is the ultimate source of variation. D. DNA polymerase (the enzyme that copies DNA) is remarkably accurate. Moreover, an individual's set of genes can be altered by mistakes, or mutations, in copying the DNA code.

The concept of sudden genetic change which breeds true in a species is represented as Mutation 2. 1. (5) 11. What is the original source of variation that natural selection can act upon? This genetic shuffling is another important source of genetic variation. As other users have highlighted in their answers, many mutations (incl. A gene mutation is an alteration in the DNA nucleotide If mutations are the ultimate source of genetic variation and mutations are random, how can evolution "move" a population in a particular direction? Which of the following processes is the ultimate source of the genetic variation that serves as raw material for evolution? Mutations are the ultimate source of genetic variation. Mutation is the ultimate source of all genetic variation, providing the raw material on which evolutionary forces such as natural selection can act. Sources of acquired variations are apparent. nonsense and missense mutations Frame-shift mutation e.g. Important to point out that existing variation can be reshuffled by a variety of mechanisms that we don't always consider as mutations leading to increases or decreases in variation and thus altering the potential for evolution. Thus mutation is responsible for appearance of a phenotypic variation. insertion or deletion mutations Any change in genetic DNA will be translated into a defect in the corresponding protein. We have learned that genetic variation is essential for evolution to occur. Any external condition, influencing the organism, produces this type of variation. Ask a Doubt. Mutations are mistakes that occur in DNA sequence of genome: Point mutation e.g. Gene flow is any movement of genes from one population to another and is an important source of genetic variation. Without variation, there could be no evolution, so mutations are of great importance to evolution. Natural Selection: Survival and reproduction of the fittest 3. Mutation is mia Could ablution is caused by the accumulation off mutations that occur over time. These variations, because they are somatic, may not be inherited. Add your answer and earn points.
