A silent mutation has the least effect on an organism. It is when the codon is changed to the same amino acid.
A silent mutation
A mutation in a person's skin cells would be least likely to impact their ability to produce insulin as insulin is primarily produced by pancreatic cells. Skin cells are not directly involved in insulin production or regulation.
An organism must be composed of at least one cell.
Long ago, there was one generic type of bear. Now, because of divergent evolution, there is a brown bear and a polar bear, each adapted to their own environment. Another example is the famous finch observations that Charles Darwin made. He has discovered that through geographical isolations, speciation has divided the finch into various species of finches.
A DNA substitution would have the smallest effect if it occurs in regions of the DNA that do not encode for a protein, such as in non-coding regions or introns. These substitutions may not result in a change in the final protein product or its function.
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 single base substitution mutation is least likely to be deleterious when it occurs in a non-coding region of DNA, such as in an intron or in a region with no functional significance. Additionally, if the mutation results in a silent or synonymous change in the amino acid sequence, it may not have a noticeable effect on the protein's function.

The least likely effect of pesticide use is improved biodiversity. Pesticides are designed to control or kill pests, which can disrupt the balance of ecosystems and harm biodiversity.
Of the three organisms it is the snails that has the least chance of becoming a fossil since it has no skeleton.
Items least likely to be remembered are the items in the middle. Unless the items in the middle are extremely odd.The Serial Position Effect is the theory that we are more likely to remember the items at the start or end of a list.
