whats an example of a neutral,harmful, and helpful mutation?

Answer 1

Neutral mutation might be a sixth toe....doesn't help...doesn't hurt.

Harmful mutation would be something like heart outside the chest which is fatal.

Helpful mutation would be something like being very tall or a prodigy situation


Mutations are the basis behind all evolutions

Answer 2

Neutral: A mutation that neither helps nor harms the individual. Say an indoor cat with rounded claws instead of sharp.

Harmful: A mutation that kills the individual or makes it infertile. For example a squirrel born without ovaries.

Helpful: A mutation that increases the chance of an individual surviving and having offspring. Example - a squirrel has camouflage fur.

Answer 3

Neutral: "Neutral mutations are defined as mutations whose effects do not influence the fitness of either the species or the individuals who make up the species." An example of this could be the change of eye-color in an offspring.

Harmful: "Amorphic (loss-of-function) mutations are the result of gene product having less or no function" could be harmful. And "Lethal mutations are mutations that lead to a phenotype incapable of effective reproduction" which is most harmful. An example of this could be offspring that are more susceptible to a disease.

Helpful: "Neomorphic (gain-of-function) mutations change the gene product such that it gains a new and abnormal function." "A very small percentage of all mutations actually have a positive effect. These mutations lead to new versions of proteins that help an organism and its future generations better adapt to changes in their environment" An example of this could be offspring that are less susceptible to a disease.
