Question

explain ways in which genetic variation and environmental factors contribute to evolution by natural selection and diversity

Answer 1

Answer:

natural selection is caused so that an organism can adapt and better survive in their environment.

Explanation:

Natural selection is considered as the key mechanism of the evolution process. It is defined as the differential survival as well as the reproduction of the individuals that is due to the differences in the phenotype. The genetic variations in the species and the various environment factors are generally passed on to the next generation, which is known as the natural selection if any particular trait or features of the species helped them to survive in that environment and also to reproduce. It is caused because the species can survive and adapt better in their environment.

Answer 2

Answer: 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 variation is advantageous to a population because it enables some individuals to adapt to the environment while maintaining the survival of the population.
