Question

Define variation in relation to a species. Why are variations beneficial to the species?

Answer 1

Define variation in relation to a species. ... Variation means certain changes which occur in sexually reproducing organisms because of errors in DNA copying. Variations arebeneficial for species because they give survival advantage even in the adverse environmental conditions

Answer 2

HEY MATE HERE IS YOUR ANSWER:-

Variation is referred to ‘ not being identical but differ in appearance' (phenotypic as well as genotypic expression). Genetic variation occurs even in identical twins.
Genetic diversity, differences within a species.variation may be defined as the differences among the individual of the same species. Intra specific variation among the different genera. They have two types somatic variation and germinal variation

IMPORTANCE:-
They make an organism better fitted to struggle for existence in a particular environment. They also enable human beings to improve the races of important plants and animals. However, they are unable to form a new species though Darwin (1859) based hisevolution theory of natural selection on continuous variations. 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 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.
