the ultimate source of variation is

Without variation there could be no evolution, so mutations are of great importance to evolution. Mutation 2. Gene flow: Migration, movement and hybridization Macroevolution: the concept 1. which of the following processes is the ultimate source of the genetic variation that serves as raw material for evolution. A heterozygote is an individual with a different paternal and maternal allele at a particular locus. Options (a) natural selection (b) mutation (c) sexual reproduction (d) hormonal effects. Gene flow is any movement of genes from one population to another and is an important source of genetic variation. Sex can introduce new gene combinations into a population. Ultimate source of organic variation is the process which provide raw materials for evolution is
Or
The concept of sudden genetic change which breeds true in a species is represented as (5) 10. garvit28 garvit28 DNA copying is the ultimate source of variation. Website not working properly (1) (2) (3) (4) Yes 4. The external factors may be light, heat, cold, food etc. Add your answer and earn points.

Sexual reproduction: Recombination of genes, mate choice 4. The ultimate source of variation is . Thus mutation is responsible for appearance of a phenotypic variation. Without variation, there could be no evolution, so mutations are of great importance to evolution. Correct Answer: mutation. Here we have sexual reproduction, mutation, genetic drift and natural selection. nonsense and missense mutations Frame-shift mutation e.g. The ultimate source of allelic variation is: (1) Recombination (2) Natural selection (3) Mutation (4) Drift. Variation in a population often results from natural selection, random genetic drift, emigration, or mutation. A) Mutation B) Gene flow C) Genetic drift D) All of the above.

The strength and direction of selection depends on the environment. Mutation is the ultimate source of genetic variation. (Points : 4) Environmental change Mutations Selective breeding Random chance Sexual Reproduction 9. So the answer for this question is auction, eh? Natural Selection: Survival and reproduction of the fittest 3. 1. It generates the alleles that are required for a population to adapt to a particular habitat. Related Questions: In how many steps is ATP utilised in glycolysis The most important requirement for the evolution is variation. As other users have highlighted in their answers, many mutations (incl. 3. A condition necessary for evolution to occur is that there must be genetic variation among the excess offspring produced. 9.

Mutation is the ultimate source of variation. A gene mutation is an alteration in the DNA nucleotide This genetic shuffling is another important source of genetic variation. Mutation is the ultimate source of genetic variation, but mechanisms such as sexual reproduction and genetic drift contribute to it as well. Ask a Doubt. Answer. 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! Favorite Answer Mutations are very strong contributors to genetic variation within a population, but independent assortment and dna recombination during sexual reproduction can … The cause of evolution, really speaking, comes from the germinal variation which is inheritable. The ultimate source of genetic variation and the basis for the diversity of life on Earth is evolution. One of the most important factors of the development of a new species is the geographical isolation. New questions in Social Sciences. From this perspective, mutation is a "good" thing. general-biology; 0 Answers. Polyploidy is an example of chromosomal mutation. The ultimate source of organic variation is not natural selection, sex … However, they usually occur at very low frequency. The modern synthesis refers to the combination of modern genetics and Darwinism. The allele does not affect the fitness of the individual carrying the mutation. 8. Mutations are the ultimate source of genetic variation. The mutation is the ultimate source of genetic variation, but mechanisms such as sexual reproduction and genetic drift contribute to it as well. There are several types of mutations, both at the gene-level and the chromosome-level. 0 votes. Genetic shuffling is a … Explanation: No explanation available. D. All of the above. Ultimate source of variation is MUTATION and nothing else. Genetic variation is the difference in DNA among individuals or the differences between populations. These variations, because they are somatic, may not be inherited. Random mutations are the ultimate source of genetic variation. B. Mutation is the ultimate source of all genetic variation, providing the raw material on which evolutionary forces such as natural selection can act. Organisms evolve and develop adaptations in order to survive in their environments. Assume a mutation resulting in a novel allele occurs in a gene of one individual in a population of 500 diploid individuals.
