A mistake in DNA replication before meiosis produces an organism that is better able to outrun predators.
Explanation:
The genetic variation results from the different alleles of a population. The mutation or mistake in DNA replication would cause gene variants which may be beneficial. The variation in the DNA sequence of genome results in variants in small population.
Genetic variation is the cause of natural selection and eventually, evolution takes place with beneficial traits.
It is mentioned in the question that resulting offspring having received the mutant allele could result in better surviving capabilities or phenotypic traits as they are able to outrun predators.
Some 40% of the world's people suffer from micronutrient deficiencies. In the name of the poor, genetic engineering is being promoted as the solution to this problem. Researchers have developed transgenic rice containing beta-carotene and claim it will combat Vitamin A deficiency in rice-eating regions.
