Detailed explanation-1: -A single mutation can have a large effect, but in many cases, evolutionary change is based on the accumulation of many mutations with small effects. Mutational effects can be beneficial, harmful, or neutral, depending on their context or location.
Detailed explanation-2: -No; only a small percentage of variants cause genetic disorders-most have no impact on health or development. For example, some variants alter a gene’s DNA sequence but do not change the function of the protein made from the gene.
Detailed explanation-3: -Mutations result when the DNA sequence in an organism changes and are the main cause of diversity in organisms. Proteins are complex molecules that play a critical role in organisms. Mutations in the DNA sequence can lead to changes in protein structure. Some mutations can be beneficial.
