The mutation that has the greatest effect is one that is not only beneficial but that is heavily selected for by the environment. Ideally dominant as it will effect the population more rapidly than a recessive trait.
Only traits that are selected for or against in a population change the frequency of the occurance of the alleles in the population.
A point mutation, in which one nitrogen base in a codon is substituted for another, may have no effect on an organism. This is true if the base substitution does not change the amino acid that the codon represents, or if the mutation occurs in a non-critical location in the protein so that the protein's structure is not changed significantly and the protein is still able to function.
A deleterious mutation has a negative effect on the phenotype, and thus decreases the fitness of the organism. (A harmful mutation)
The location of the mutation within the genome, the type of mutation (e.g., missense, frameshift), and its effect on gene function or protein structure typically determine the magnitude of a mutation's effect. Additionally, the degree to which the mutation disrupts important cellular processes or regulatory mechanisms can also influence its impact.
The mutation may be passed on to an offspring. Depending on the mutation, it may have no effect, or it could be lethal.
No one knows what effect a mutation may have. Most are not viable.
If the point mutation does not change the protein to be translated in the 3-letter sequence, then it will have no effect on the gene's function.
Well a Silent Mutation does not affect anything so it isn't bad so its a good mutation.
A mutation in a sex cell has the potential for great effect because it can be passed on to offspring and result in genetic changes in future generations. This can lead to a variety of outcomes, such as genetic disorders or adaptations that may affect the fitness of the species.
A mutagen is a substance that CAUSES a mutation. Essentially, mutagens are the cause, mutations are the effect. Simple as that :)
A point mutation may have no effect on an individual's fitness if it occurs in a non-coding region of the DNA or if it results in a silent mutation that does not change the amino acid sequence of a protein. In these cases, the mutation does not impact the individual's ability to survive and reproduce, so it does not affect their fitness.
More varity in a population
One positive effect of mutation is that it can introduce genetic diversity within a population, allowing for greater adaptability to changing environments and potentially leading to evolutionary advancements. Conversely, a negative effect of mutation can be the development of harmful genetic disorders or diseases, which can adversely affect individuals and populations.
