The variation is important and beneficial for species as it allows a species to adapt to a changing environment. … Only those who adopt the changes can survive in harsher conditions by adapting to the changes. For an individual, the variation doesn’t matter in most of the conditions.
What is variation and why is variation in species important?
The differences between the individuals in a species is called variation. Variation helps a species to survive, by causing individuals of a species to be genetically and physically different.
What is importance of variation?
Genetic variationis advantageous to a population because it enables some individuals to adapt to the environment while maintaining the survival of the population. Genetic variation creates a larger pool of traits in a species so that given a novel environment, at least someone would have the trait needed to survive.
Why is variation important in an ecosystem?
Variation within species affects how organisms interact with each other and their surrounding environment. For example, the size of a fish’s mouth, known as its gape, determines the size of prey it can eat. And the variety of noxious chemicals a plant produces controls which insects chew its leaves.
Why is variation beneficial to the species but not necessarily for the individual Brainly?
Answer: Variations are beneficial to the species than individual because sometimes for a species, the environmental conditions change so drastically that their survival becomes difficult. … However, if these variants were not there, then the entire species of bacteria would have been destroyed.
Why is variation beneficial to the species but not necessary for the individual Meritnation?
why is variation beneficial to the species but not necessary for the individual ? Variation is necessary for the survival of species as variation makes species more adapted to survive with the changing conditions. … Thus variation at individual level is not so useful as a person does not evolve by these variations.
How does variation in species promote survival?
The changes in the environment brings out Variations in the species. … Such variations enable stability to the population of various species by preventing them from getting wiped out during adverse conditions. Thus, variations help a species in survival.
Why is variation important in reproduction?
In nature, variations occur during sexual reproduction. If this variation is beneficial to the species, it is selected and remains in the population. This is because the variant species are more adapted. Therefore, they can survive better and reproduce to pass the genes to the offsprings.
How does variation enable the survival of species in a change environment?
Genetic variations that alter gene activity or protein function can introduce different traits in an organism. If a trait is advantageous and helps the individual survive and reproduce, the genetic variation is more likely to be passed to the next generation (a process known as natural selection).
Do variations in a species have equal chances of surviving in the environment?
Answer: (d) All variations in a species do not have equal chances of survival. Some of the variations may be so drastic that the new DNA copy cannot work with the cellular apparatus it inherits. … In asexual reproduction, there is minimum variation that is due to small errors in DNA copy.
What is variation How is variation created in population How does the creation of variation in species promote survival?
Variations Promote the survival of the species as variations allow them to adapt and survive to the changing environment and connections. Different species have different kin of advantages depending on the nature of variation. (b) Gametes are produced through meiosis.
What is the importance of DNA copying in reproduction Why is variation beneficial to the species but not necessary for the individual explain?
DNA copying is essential part of reproduction because it ensures that same blue print of the body design is maintained. Variation for the species is beneficial for adaptation and better survival.
What is variation class 10th?
Variation is the change in characters or traits of an individual which has not existed in their parents. Variations can be of many types. If mutation occurs, there is a sudden change in the number or structure of genes or chromosomes.
What is the basis of variations being produced during reproduction?
Genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism’s offspring).
Why is variation beneficial to the species but not necessary for the individual give three reasons?
Variation is beneficial for the existence of the species because they play an important role in the adaption to survive in the changing conditions. Variation is not essential for an individual because it doesn’t help in the evolution of a human being or a person.
Why is variation not necessarily beneficial for an individual?
Hint: The variation in species is important because it helps to establish more suitable progeny and adaptability of organisms in relation to the changing environment. … – So, due to this the variation at species level is beneficial for evolution and survival but not necessarily for an individual.
Why variation is not beneficial for individuals?
Variations give organisms an individuality of their own. In the absence of variation, there would be no science of heredity as all individuals of a race would be identical to one another in all aspects.
How does variation within a species contribute to the health of the species?
How does variation within a species contribute to the health of the species? … The more variation the healthier the species as a whole. If environment changes then there is a chance that a gene will become advantageous and the species may survive.
Why is variation important to biodiversity?
Abstract: Biodiversity is mostly discussed at the level of species, but genetic variation within species may be as important as variation between species. It enables organisms to adapt to environmental changes. … Many other organisms must be genetically ‘prepared’ to meet environmental changes.
Why are there so many variations of species?
Just why some groups contain large numbers of species while others don’t has long puzzled biologists. One of the main explanations has been geological age – older groups of organisms are more diverse because they have simply had more time to accumulate greater numbers of species.
Why are variation important to the survival of a population?
Demonstrating in which ways genetic variation is advantageous to a population because it enables some individuals to adapt to the environment while maintaining the survival of the population.
How does the creation of variation in the species?
The geographical isolation of individual of a species leads to genetic drift. This limits the sexual reproduction of the separated population. This results in separated individuals reproducing among themselves. This leads to the formation of a new variation.
How is variation produced in species?
Genetic variation within a species can result from a few different sources. Mutations, the changes in the sequences of genes in DNA, are one source of genetic variation. … Finally, genetic variation can be a result of sexual reproduction, which leads to the creation of new combinations of genes.
