how does the cseation of variation in a species promote variation
Answers
Sexual reproduction helps to achieve variation in newborn offsprings. It is created due to different DNA copyings of two different parents. Variation helps to achieve diversity. It does also ensure humankind does not get swiped easily by a natural calamity, disaster, drought or man-made explosions, wildfires or tsunamis.
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.
