What are advantages of variation?

Answer 1

Advantage- On the species level, variation allows a population to maintain a healthy diversity, allowing it to cope with changing circumstances.

Disadvantage- On the individual level, variation may lead to detrimental changes as well as neutral and beneficial changes.

Answer 2

it helps a species to survive,it also helps us to determine who is who,it helps organisms to adapt to their environment as well as to changes which do occur in the environment,however it also helps a species to emerge strong if favoured by natural selection.variation helps a species to be resistant to diseases,thus if a species is to survive there has to be variation.

Answer 3

Variation allows for genetic diversity within a population, which can increase the likelihood of some individuals surviving environmental changes. It also provides the raw material for natural selection to act upon, driving evolutionary change. Additionally, variation can lead to specialization and adaptation to specific ecological niches.

Answer 4

If we were all genetically the same, for example, and if someone had a disease, we would all die.
