Importance of Variation
Due to the change in the body size and DNA it is difficult for the species to survive in certain environment conditions. In these climatic or environmental changes the variation in organisms help them to adapt to different environment such as temperature, food resource and climate conditions. Therefore variation is important in organisms to be resistant to multiple diseases which helps these organisms to survive in such conditions.
Do Organisms Create Exact Copies of Themselves? – Class 10 Notes
Organism consists of similar body structure. The DNA molecules that are found in the chromosome in the nucleus of the cell are responsible for the transfer of characters from the parents to the offspring. During the process the sexual reproduction these cells produce two copies of DNA which further separate into two cells. These two DNA copies will not be identical to each other but they consist of some similarities. Therefore these two organisms will have some variation from their parents.
