mutations in multiple genes
MUTATIONS
the answer is mutations.......................
usually adaptation but mutations could happen
It is called mutations. I'm 100% sure.
Usually mutations have deleterious effects to the organism, but occasionally there are beneficial mutations. Such mutations drive evolution.
Mutations are random. They may be beneficial, detrimental, or have no effect at all.
No not all mutations are bad there are good mutations and bad mutations
Since mutations are usually caused by radiation, I would say people have more mutations. A lot of what we use everyday causes radiation. Cell phones, computers, etc.
Successful mutations will persist. Mutations usually occur during replication. Some mutations will flourish depending on environmental factors.
By colours you mean mutations. Budgies come in many different mutations. This is a good guide to mutations: http://www.budgieplace.com/colors.html
mutations in multiple genes
It produces new varieties .
More variety in a population.
A third arm wouldn't be bad.
Two types of mutations are Point Mutations and the other is Frameshift Mutations. Piont mutations include; deletions, insertions, and substitutions. These mutations casue a slight change in the amino acid usually resulting in a change in one amino acid. The second type, frameshift mutations involve many changes and almost always results in many changes in the codons.
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.
