Genetic shuffling is a … A.Mutation occurs in response to natural selection. (5) 11. Favorite Answer Mutations are very strong contributors to genetic variation within a population, but independent assortment and dna recombination during sexual reproduction can … "Mutation proposes and selection disposes." Mutation 2. Explain why it is easier for a stem cell to become cancerous that a fully differentiated cell (brain cell) to become cancerous. Gene mutations provide new alleles, making these mutations the ultimate source of variation. insertion or deletion mutations Any change in genetic DNA will be translated into a defect in the corresponding protein. The ultimate source of all new genetic variation is: a) mutation. Explanation: No explanation available. The strength and direction of selection depends on the environment. Random mutations are the ultimate source of genetic variation. 3. @5. 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. Mutation is mia Could ablution is caused by the accumulation off mutations that occur over time. C.Mutation is the only source of new alleles. Genetic variation can refer to differences between individuals or to differences between populations. The cause of evolution, really speaking, comes from the germinal variation which is inheritable. Q12: Doubts . The ultimate source of variation is . However, they usually occur at very low frequency. A condition necessary for evolution to occur is that there must be genetic variation among the excess offspring produced. What is the ultimate source of all new genetic variation? A. Fertilization. Be the first to write the explanation for this question by commenting below. 0 votes. Mutations are mistakes that occur in DNA sequence of genome: Point mutation e.g. Sexual Reproduction b.) From this perspective, mutation is a "good" thing. Microevolution: The agents of change 1. MUTATION AND VARIATION Mutation is the ultimate source of variation. Sex can introduce new gene combinations into a population. Mutations in genes can have no effect, alter the product of a gene, or prevent the gene from functioning properly or completely. Ask a Doubt. It generates the alleles that are required for a population to adapt to a particular habitat. The most "fit" genotypes and phenotypes can be selected from the genetic variation that exists in the population. So let's start with sexual reproduction. If mutations are the ultimate source of genetic variation and mutations are random, how can evolution "move" a population in a particular direction? Light Ultimate source of organic variation is the process which provide raw materials for evolution is

The concept of sudden genetic change which breeds true in a species is represented as Mutations are the ultimate source of genetic variation. One of the most important factors of the development of a new species is the geographical isolation. Genetic variation is the difference in DNA among individuals or the differences between populations. both A and C As other users have highlighted in their answers, many mutations (incl. Mutation is the ultimate source of variation. 8. general-biology; 0 Answers. 1. Gene flow: Migration, movement and hybridization Macroevolution: the concept 1. Mutation can result in many different types of change in sequences. a.) 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! Thus mutation is responsible for appearance of a phenotypic variation. Sources of acquired variations are apparent. What kind of mutation is likely involved in generating new variation? Wrong Answer Wrong Explanation Wrong Question Question not related to topic Spelling Mistakes. garvit28 garvit28 DNA copying is the ultimate source of variation.

School Mountain View High School, Lawrenceville Course Title SCIENCE 509 A) Mutation B) Gene flow C) Genetic drift D) All of the above. The most important requirement for the evolution is variation. Genetic drift: changes to allele frequencies based on chance 5. This genetic shuffling is another important source of genetic variation. The only source of variation in asexual organisms is mutation. The mutation is the ultimate source of genetic variation, but mechanisms such as sexual reproduction and genetic drift contribute to it as well. Related Questions: In how many steps is ATP utilised in glycolysis Moreover, an individual's set of genes can be altered by mistakes, or mutations, in copying the DNA code. Polyploidy is an example of chromosomal mutation. Correct Answer: mutation. 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. Mutation c.) Natural Selection d.) Genetic Drift 1. Mutation is the ultimate source of genetic variation, but mechanisms such as sexual reproduction and genetic drift contribute to it as well. A heterozygote is an individual with a different paternal and maternal allele at a particular locus. Add your answer and earn points. Organisms evolve and develop adaptations in order to survive in their environments. 9. Without variation, there could be no evolution, so mutations are of great importance to evolution. Options (a) natural selection (b) mutation (c) sexual reproduction (d) hormonal effects. What is the original source of variation that natural selection can act upon? B. Meiosis. Without variation there could be no evolution, so mutations are of great importance to evolution. Also Know, what is the ultimate source of all variation in and among populations? New questions in Social Sciences. synonymous mutations but not only and soma mutations) do not bring up any the underlying genetic variance of phenotypic traits. Sexual reproduction: Recombination of genes, mate choice 4. These variations, because they are somatic, may not be inherited. The ultimate source of variation is. Gene flow is any movement of genes from one population to another and is an important source of genetic variation. D. All of the above. Evolution leads to adaptation. There are several types of mutations, both at the gene-level and the chromosome-level. The ultimate source of organic evolution is the mutation. We know that sexual reproduction has a lot of genetic variation. Any external condition, influencing the organism, produces this type of variation. _____ is (are) the ultimate source of new variation in a population. Answer. Variation in a population often results from natural selection, random genetic drift, emigration, or mutation. Yes, mutations are the ultimate source of genetic variation in populations, while genetic drift and directional selection removes variation. The external factors may be light, heat, cold, food etc. Here we have sexual reproduction, mutation, genetic drift and natural selection. Mutation is the ultimate source of genetic variation. (Points : 4) Environmental change Mutations Selective breeding Random chance Sexual Reproduction 9. Which of the following processes is the ultimate source of the genetic variation that serves as raw material for evolution? So the answer for this question is auction, eh? The ultimate source of allelic variation is: (1) Recombination (2) Natural selection (3) Mutation (4) Drift. Mutation is the ultimate source of all genetic variation, providing the raw material on which evolutionary forces such as natural selection can act. The modern synthesis refers to the combination of modern genetics and Darwinism. Furthermore, because mutation is the ultimate source of all genetic variation, clarifying why mutation rates vary is crucial for understanding all areas of biology.
