Why do we need variation?

Why do we need variation?

Different species have different characteristics from each other. This means that no two members of a species are identical. 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.

Why is variation important in a species?

Having variation within a species means that if the environment changes there may be individuals within the species more able to withstand the change and survive. it produces variation in the offspring. the species can adapt to new environments due to variation, which gives them a survival advantage.

Why is variation in a population necessary for the population survival?

Genetic variation is an important force in evolution as it allows natural selection to increase or decrease frequency of alleles already in the population. Genetic variation is advantageous to a population because it enables some individuals to adapt to the environment while maintaining the survival of the population.

What is variation and write its importance?

Variation help in survival of the organism by many different ways- (i)It helps a species to survive. (ii)It also helps organisms to adapt to their environment as well as to changes which do occur in the environment. (iii)It also helps a species to emerge strong if favoured by natural selection.

Why are variations important how are variations useful for an organism on a population?

Variations are useful for an organism or a population in following ways: It increase the chance of survival. It provide the barrier to fight against the predator of the organism. It helps the organism to adapt the changing environment.

What is the importance of genetic variation in wildlife population?

Genetic variation could provide a means for a species to survive environmental change when certain individuals have traits that allow survival.

Is variation necessary?

It helps in better survival of an organism. Accumulation of a particular variation over time leads to speciation. Variation results in genetic drift where same species are distanced. The useful variations are passed on to the next generation which is necessary for adaptation of an organism.

Why is variation is not necessary for individual?

Variation is necessary for every individual. 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.
