This not only depends on what changes the mutations have bought about but also who the mutations have happened to, human, bacteria, elephant. They can be bad, such as the koala mutation, their DNA has been mutated by an AIDs like virus, each generation is at risk of death at early age. Or there could be good mutations such as fishes growing legs millions of years ago so they could walk, although that would be classified as evolution.
A2:
Most mutations are lethal.
It is something like a bunch of monkeys with typewriters--every so often a Shakespearian Sonnet will be written...a helpful mutation would be about that rare.
What else would they be?
If something mutates, the results are either beneficial and do something good; or they are harmful.
Even if you were to try and claim the result "neutral", most would argue that the mutation itself even if it is not majorly harmful would at least qualify as a nuisance (a mild harm) by simply being in the way or changing the normal expectation in some way.
There aren't really any other categories for mutations to fall under. Mutations that help are beneficial and mutations that do nothing or worse than nothing are harmful.
They can be both. There are mutations that allow people to be naturally immune to HIV, but there are also mutations that can increase a person's risk to some diseases like CVD (Cardiovascular Disease). Mustations are very uncommon, but in Viruses it can be seen more often. Mutations gave arize to viruses like MRSA, which is immune to antibiotics.
They can be either by helping species evolve or by causing cancer

Usually mutations have deleterious effects to the organism, but occasionally there are beneficial mutations. Such mutations drive evolution.
Mutations are random changes so there is no way to predict what kind of effect they will have.
it is a beneficial plant
Mutations are both! Mutations lead to genetic variation. (so does fertilization) It gives the organism greater chance of survival if the environment changes. Mutations could lead to different height or eye color etc. They could also lead to disadvantages as well. If the adaptation in an environment is tall and a mutation is made for short then the mutation isn't very advantagoes. If the environments adaptation is for an immunity to a chemical like pesticides vs bugs and a bug has an immunity due to mutation then it is beneficial
Three types of gene mutations are substitution, insertion, and deletion. Another gene mutation would be frame shift. All these mutations can cause deformities of the gene.
Mutations that succeed [are beneficial] provide Evolution, so not at all.
Genetic mutations are not always harmful to the individual. A few may be beneficial.
Well, there is no specific type of mutation that is beneficial. They can be harmful, helpful, or have no effect at all.

Mutations
Not all mutations are harmful. The improvements in creatures through evolution are from beneficial mutations. The beneficial mutations increase the creature's chance of survival and passing along those new beneficial genes to its offspring.
No. Although there is a chance of a beneficial mutation, the chance of it occurring is almost astronomical. Most mutations are harmful to humans.
They can certainly be either. When researching it closely scientists have found a lot of mutations which don't seem to have any influence. "Bad" mutations tends not to be functional, and often disappear pretty much by themselves one way or another.
Mutations are changes in DNA. Most are neutral or beneficial. Mutations have allowed animals to adapt to new environments and new species to evolve.
"...999/1000 are harmful or fatal and the remainder may be beneficial. (Remine, The Biotic Message, page 221."
Usually mutations have deleterious effects to the organism, but occasionally there are beneficial mutations. Such mutations drive evolution.
Some mutations can be deadly, harmful, or have no effect. Correct, not all mutations are harmful. Some mutations could even have a positive effect and help the creature adapt.
