Mutations can be categorized based on the kind of effect they have on an organism. blue eyes in humans are a result of a mutation in the oca2 gene, which controls the production of the pigment melanin in the iris. this mutation is an example of a (beneficial, harmful, neutral) mutation. such mutations have (a positive, a negative, no) effect on an organism’s survival.

small, big, or no change could occur in the phenotype. it could cause something as simple as a cats ears to curl backwards or something as frighting as death. it could also occur in the protien-coding area and have an effect on that but no effect on the amino acids. what has to occur is a changing in the hox gene or the control gene.
