Detailed explanation-1: -A genetic mutation is a change to a gene’s DNA sequence to produce something different. It creates a permanent change to that gene’s DNA sequence. Genetic variations are important for humans to evolve, which is the process of change over generations. A sporadic genetic mutation occurs in one person.

Detailed explanation-2: -The mechanisms of evolution-like natural selection and genetic drift-work with the random variation generated by mutation. Factors in the environment are thought to influence the rate of mutation but are not generally thought to influence the direction of mutation.

Detailed explanation-3: -A mutation is a change in the DNA sequence of an organism. Mutations can result from errors in DNA replication during cell division, exposure to mutagens or a viral infection.

Detailed explanation-4: -“We always thought of mutation as basically random across the genome, ” said Grey Monroe, an assistant professor in the UC Davis Department of Plant Sciences who is lead author on the paper. “It turns out that mutation is very non-random and it’s non-random in a way that benefits the plant.

Detailed explanation-5: -Random Mutations The small variations contributing to the variation in human eye color are a result of mutations in DNA. These mutations are able to be passed onto the next generation because the DNA the mutation occurs in is found in the reproductive cells forming the offspring.
