More variety in a population.
No not all mutations are bad there are good mutations and bad mutations
By colours you mean mutations. Budgies come in many different mutations. This is a good guide to mutations: http://www.budgieplace.com/colors.html
It produces new varieties .
A third arm wouldn't be bad.
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.
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.
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:)

Multi-cellularity evolved from mutations. This is how everything evolved throughout history. Random mutations that prove to be advantageous, and allow a species to continue to reproduce.
Not always. there are two types of mutations, A Good mutation or a bad one. A bad mutation will happen very rarely but could still happen, The chances are almost to none But there are also good mutations, The chances of getting a good mutation are 0.001 When mutations happen, And its bad, For an example a Cell If it gets a bad mutation, It will most likely not be able to compete with other cells for resources. But if the mutation is "Good" The DNA which is a genetic code will be changed to have the good mutation put it. A good mutation for a bacteria would be antibiotic resistance. Bacteria Reproduce every 20 Minutes by dividing, So on a petri dish having the bacteria lay there for 24 hours, would have More than millions of Bacteria on it. And in those moments of reproducing a Good or bad mutation WILL happen. When you use hand sanitiser you kill germs right? But hand sanitiser says 99.99%, The .001% that lives has a good mutation that makes is be Resistant to antibiotics
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.
SCID can be caused by a variety of genetic mutations, including both frameshift and point mutations. Frameshift mutations involve the insertion or deletion of nucleotides that shifts the reading frame of a gene, while point mutations involve the substitution of a single nucleotide.
