The ultimate source of variation in population for organic evolution 1 See answer muzzu8086 is waiting for your help. A.Mutation occurs in response to natural selection. 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. Random mutations are the ultimate source of genetic variation. The most important requirement for the evolution is variation. The allele does not affect the fitness of the individual carrying the mutation. We have learned that genetic variation is essential for evolution to occur. We know that sexual reproduction has a lot of genetic variation. 8. Mutation can result in many different types of change in sequences.

The concept of sudden genetic change which breeds true in a species is represented as Yes, mutations are the ultimate source of genetic variation in populations, while genetic drift and directional selection removes variation. Variation in a population often results from natural selection, random genetic drift, emigration, or mutation. A gene mutation is an alteration in the DNA nucleotide Mutation: The ultimate source of variation 2. A condition necessary for evolution to occur is that there must be genetic variation among the excess offspring produced. Sexual reproduction: Recombination of genes, mate choice 4. insertion or deletion mutations Any change in genetic DNA will be translated into a defect in the corresponding protein. The most "fit" genotypes and phenotypes can be selected from the genetic variation that exists in the population. Ask a Doubt. The ultimate source of variation is. Light (5) 10. D. All of the above. Mutations are the ultimate source of genetic variation. 0 votes. general-biology; 0 Answers. There are several types of mutations, both at the gene-level and the chromosome-level. Here we have sexual reproduction, mutation, genetic drift and natural selection. Ultimate source of variation is MUTATION and nothing else. Gene mutations provide new alleles, making these mutations the ultimate source of variation. New questions in Social Sciences. Mutations are mistakes that occur in DNA sequence of genome: Point mutation e.g. 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? 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. A. Fertilization.
