The concept of sudden genetic change which breeds true in a species is represented as A condition necessary for evolution to occur is that there must be genetic variation among the excess offspring produced. The ultimate source of genetic variation and the basis for the diversity of life on Earth is evolution. The modern synthesis refers to the combination of modern genetics and Darwinism. Light Options (a) natural selection (b) mutation (c) sexual reproduction (d) hormonal effects. asked Sep 9, 2016 in Biology & Microbiology by Cleopold. A.Mutation occurs in response to natural selection. Natural Selection: Survival and reproduction of the fittest 3. 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. Be the first to write the explanation for this question by commenting below. Ask a Doubt. Which of the following processes is the ultimate source of the genetic variation that serves as raw material for evolution? 3. Mutation is mia Could ablution is caused by the accumulation off mutations that occur over time. a.) Here we have sexual reproduction, mutation, genetic drift and natural selection. There are multiple sources of genetic variation, including mutation and genetic recombination. So let's start with sexual reproduction. Mutation is the ultimate source of genetic variation, but mechanisms such as sexual reproduction and genetic drift contribute to it as well. 0 votes. B. Meiosis.

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. Organisms evolve and develop adaptations in order to survive in their environments. The ultimate source of all new genetic variation is: a) mutation. Mutation is the ultimate source of variation. There are several types of mutations, both at the gene-level and the chromosome-level. Yes 4. Moreover, an individual's set of genes can be altered by mistakes, or mutations, in copying the DNA code. Mutations are the ultimate source of genetic variation. From this perspective, mutation is a "good" thing. Thus mutation is responsible for appearance of a phenotypic variation.

The strength and direction of selection depends on the environment. These variations, because they are somatic, may not be inherited. The ultimate source of allelic variation is: (1) Recombination (2) Natural selection (3) Mutation (4) Drift. A heterozygote is an individual with a different paternal and maternal allele at a particular locus. Mutation 2. 9. Without variation there could be no evolution, so mutations are of great importance to evolution. If mutations are the ultimate source of genetic variation and mutations are random, how can evolution "move" a population in a particular direction? 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. Ultimate source of variation is MUTATION and nothing else. Genetic variation is the difference in DNA among individuals or the differences between populations. This genetic shuffling is another important source of genetic variation. One of the most important factors of the development of a new species is the geographical isolation. The cause of evolution, really speaking, comes from the germinal variation which is inheritable. Gene flow is any movement of genes from one population to another and is an important 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. @5. So the answer for this question is auction, eh? Mutation is the ultimate source of genetic variation. Genetic variation can refer to differences between individuals or to differences between populations. Any external condition, influencing the organism, produces this type of variation. What is the ultimate source of all new genetic variation? Without variation, there could be no evolution, so mutations are of great importance to evolution. What is the original source of variation that natural selection can act upon? Mutation c.) Natural Selection d.) Genetic Drift 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. 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! Sources of acquired variations are apparent. Furthermore, because mutation is the ultimate source of all genetic variation, clarifying why mutation rates vary is crucial for understanding all areas of biology.

The concept of sudden genetic change which breeds true in a species is represented as Gene flow: Migration, movement and hybridization Macroevolution: the concept 1. The only source of variation in asexual organisms is mutation. Q12: Doubts . The most "fit" genotypes and phenotypes can be selected from the genetic variation that exists in the population. (5) 11. Add your answer and earn points. As other users have highlighted in their answers, many mutations (incl. Evolution leads to adaptation. Polyploidy is an example of chromosomal mutation. Mutations in genes can have no effect, alter the product of a gene, or prevent the gene from functioning properly or completely. 1. Favorite Answer Mutations are very strong contributors to genetic variation within a population, but independent assortment and dna recombination during sexual reproduction can … D. DNA polymerase (the enzyme that copies DNA) is remarkably accurate. The ultimate source of variation is. 8. Correct Answer: mutation. insertion or deletion mutations Any change in genetic DNA will be translated into a defect in the corresponding protein. The allele does not affect the fitness of the individual carrying the mutation. Random mutations are the ultimate source of genetic variation. MUTATION AND VARIATION Mutation is the ultimate source of variation. Mutation: The ultimate source of variation 2. Explain why it is easier for a stem cell to become cancerous that a fully differentiated cell (brain cell) to become cancerous. The ultimate source of organic variation is not natural selection, sex … D. All of the above. A gene mutation is an alteration in the DNA nucleotide The ultimate source of organic evolution is the mutation. garvit28 garvit28 DNA copying is the ultimate source of variation. Variation in a population often results from natural selection, random genetic drift, emigration, or mutation. 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. So the automated source off off variation is mutation. Wrong Answer Wrong Explanation Wrong Question Question not related to topic Spelling Mistakes.
