Are all changes to our genes
good, bad, or neutral?

No only a small percentage of mutations cause genetic disorder most have no impact on health or development. For example, some mutations alter a gene's DNA sequence but do not change the function of the protein made by the gene. Often, gene mutations that could cause a genetic disorder are repaired by certain enzymes before the gene is expressed

Explanation:

Hope this helps!

The majority of mutations are neutral in their effects on the organisms in which they occur. Beneficial mutations may become more common through natural selection. Harmful mutations may cause genetic disorders or cancer

Explanation:

the answer is definitely c.

a is the correct answer
