Detailed explanation-1: -A mutation occurs in a particular animal and quickly begins to increase in frequency throughout the population. Which of the following are you most likely to conclude? The mutation increase the probability that the animal will reproduce.
Detailed explanation-2: -Environmental exposures such as tobacco smoke, UV light, and aristolochic acid can result in increased mutation rates in cancer genomes. Mutation rates across individuals are also impacted by variability in the activity of certain cellular processes.
Detailed explanation-3: -Over thousands of generations, many mutations will be introduced into a population and some of these will increase to a detectable frequency as a result of selection or genetic drift. Both of these processes may take a long time to make a measurable increase in allele diversity.
Detailed explanation-4: -Beneficial Mutations They lead to new versions of proteins that help organisms adapt to changes in their environment. Beneficial mutations are essential for evolution to occur. They increase an organism’s changes of surviving or reproducing, so they are likely to become more common over time.
Detailed explanation-5: -Mutations add new alleles into a gene pool. This causes a change in the frequency of certain allele combinations in the population, which will cause the population to evolve over time. They are a major evolutionary force that creates new gene variations.
