Question

how does the creation of variation in a species promote survival

answer fast please ​

Answer 1

Answer:

The creation of variation in a species promote survival. All variation in species do not have equal chances to survive in the environment.

Explanation:

The nature of survival is responsible for survival of the variations. Variation helps in making the changes in the environment. It promotes species survival. They allows the members to adapt to the changing climate and habitat.

• Variation occurs due to inaccurate copying of DNA where sexual reproduction takes place.
• Variation is an important for giving chance to a species to get survive in that particular environment.
• Variation means the change in character of organisms which do not match with its parent because of inaccurate DNA copying.
• There are three types of variation :- Mutation, recombination and immigration of genes.

Answer 2

Explanation:

All the variations in the species do not have equal chances of survival in the environment. The survival of the variations depends upon the nature of variation. Different individuals have different chances. Selection of variants by environmental factors forms the basis for evolutionary processes. These variations may lead to increased survival advantages of the individuals due to positive adoption of traits or may merely contribute to the genetic drift.
