They can be both good and bad depending on the mutation. Having extra arms may be a good thing if you are an alien, but being someone with extra arms can also be a bad thing. If you are not an alien, having extra arms might not be so grand. Do normal people have extra arms? If you are a person that got offended by this, i am so truly sorry. Bye:)
No not all mutations are bad there are good mutations and bad mutations
No. But they are necessary for mutations to arise. Likewise, they are also necessary in order for mutations not to arise.
Not all mutations are bad. Some mutations can be neutral, having no effect on an organism. And in some cases, mutations can be beneficial, providing an advantage in certain environments or circumstances. However, harmful mutations can also occur, leading to genetic disorders or other negative effects.
mutations are useful but not all the time itis 99 percent are bad
Mutations are changes in an organism's DNA that can be harmful, beneficial, or have no effect at all. While some mutations can be harmful and lead to diseases or disorders, others can be beneficial and provide an advantage in certain environments. So, mutations are not always bad for an organism.
Mutations are unnatural changes in the body or behavior. They are not always bad. For instance, the skin of the poison tree frog is not really bad at all. It rubs itself on poison leaves and mutated itself not to be affected.
A third arm wouldn't be bad.
Genetic mutations can be good or bad, but evolution refers specifically to those mutations that make an organism better able to survive and to perpetuate their species, which makes them generally a good thing.
bad
"Bad Goods" are by-products of industry such as pollution or congestion which have a negitive effect on the economy.
Mutations are random... they can be good, bad, or neutral.Natural selection makes evolution a non-random process by making it more likely that organisms with bad mutations will die without mating, while those with good mutations will live on to pass the gene to the next generation making it more fit.
Genetic diseases and mutations as a result of the pairing of bad alleles.
