How do genomes of species change?
By mutations in DNA.
What is Favorable mutations?
A helpful change to someones body that not man people have.
Why are only neutral mutations useful for molecular clocks?
Only neutral mutations are useful for molecular clocks because they accumulate in the DNA of different species at the same rate, while other mutations do not.
Are mutations helpful or harmful to an organism?
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
How will mutations be useful in achieving your goal color?
If the mutations can be helpful to reach the color goal it may help the process go faster or may introduce a color that is the exact same color as your goal.
What are the evolutionary values of mutations?
Mutations have allowed species to adapt the their environment.
Mutations are a source of what in a species?
Genetic variation, which can lead to evoloution, and then potentially a new species.
Are all mutations bad.?
No not all mutations are bad there are good mutations and bad mutations
How does helpful variation accumulate in a species?
*Variation appears mainly due to mutations and it accumulates via natural selection.* Re check this answer, its not answering it! I had hw. on it and it was wrong. Change it.
What is a mutation that helps an organism to live and survive in its environment?
The mutations or other changes are adaptations.
Why do mutations that occur in the skin or nervous system tend to have little effect on the evolution of a species?
Most mutations that occur have a neutral effect, or none at all, so they would not affect evolution. Organisms with mutations that cause detrimental impact typically will not survive; therefore, they will not reproduce, and the mutation will not be passed on, so the species will not be affected overall. Beneficial mutations are typically the only mutations that will affect an organism's posterity and the evolution of its species, but good mutations are very rare. This is why most mutations have little effect on the evolution of a species.

What is Favorable mutations?
A helpful change to someones body that not man people have.
Can mutations increase the variations in a species' traits?
Yes
What is the importantce of mutations in producing genetic changes in a species?
nothing
Mutations that occur in skin or lung cells have little effect on the evolution of a species because mutations in these cells?
cannot be passed on to offspring
What causes mutations?
sunlight, radiation, and smoking
