A mutation in a man's gametes (sperm) would most likely result in genetic changes that could be passed on to his offspring. This could lead to various outcomes, including potential genetic disorders, altered traits, or increased susceptibility to certain diseases in the next generation. The specific effects depend on the nature of the mutation and whether it occurs in a gene that is crucial for development or health.
A 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.
A frame shift mutation destroys the correct sequence of amino acids from the point of the mutation. The protein produced by a frame shift mutation would more than likely be nonfunctional.
Both types of mutation have the potential to cause a large effect.In general, a frameshift mutation is more likely to cause a large effect. This is because it shifts the 'reading frame' - so that all of the subsequent codons (groupings of 3 bases that are read to determine which amino acid will be added) will be changed.A point mutation is when a single base is replaced. This can either result in the same amino acid being added to the protein being synthesised (a silent mutation), a different amino acid being added (a missense mutation) or in a STOP codon (a nonsense mutation).If a point mutation causes a premature STOP codon - this is quite likely to have a large effect on the protein.
A mutation in a gamete would be more concerning because it can be passed on to offspring and potentially affect future generations. In contrast, a mutation in a regular body cell would generally only affect the individual in which it occurs.
That species would have it's best chance of survival as a result of a mutation that has a high adaptive value that occurs in its gametes.
A mutation that can be inherited by offspring would result from a change in the DNA sequence of a germ cell (sperm or egg) in the parent. This mutation would be present in the offspring's DNA and can be passed down to future generations.

A mutation can be passed on to the next generation if it occurs in the germ cells (sperm and egg cells). The impact of the mutation on the next generation can vary depending on whether it is beneficial, harmful, or neutral. Over time, mutations can contribute to genetic diversity and evolution in a population.
If nondisjunction occurs during meiosis the result could be a wide range of mutations. Most likely it would result in mosaicism meaning there will be a mixture of affected cells and non affected cells.
A mutation in a DNA nucleotide sequence would be more harmful than a mutation in a mRNA nucleotide sequence because it could cause the synthesis of multiple nonfunctional proteins in comparison to a mutation in a mRNA nucleotide sequence that would be less harmful because it would result in a few nonfunctional proteins.
A point shift mutation is more likely to produce a neutral reaction. This is because it involves a change in one nucleotide. A frame shift mutation is more deleterious because it involves the insertion or deletion of multiple base pairs within a gene's coding sequence.
