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 a source of genetic variation that refers to a random error in the genetic code?
Mutations involve changes in the DNA code.
What is variation in evolution?
A variation of a gene is called and allele. Different alleles are caused by mutations.
Did mutations occurred in 20th century?
Yes, although mutations are rare, they are still present today meaning that they were also present during the 20th century.
What causes genetic mutations?
Mutations are changes in the nucleotide sequences in a genome. Most often, these minor mistaks are corrected by in-built repair mechanisms and many mutations go unnoticed an are not harmful. Harmful mutations cause diseases in many cases. There are several factors that promote the formation of mutations. These factors are called mutagenic agents. Mutagenic agents are divided into: chemical and physical mutagens. UV radiation is an example of a physical mutagen and Nitrous acid is an expample of a chemical mutagen
What are the evolutionary values of mutations?
Mutations have allowed species to adapt the their environment.
How can mutations affect protein synthesis in cells What is the result?
Mutations can be a source of genetic

How do genomes of species change?
By mutations in DNA.
What is the ultimate source of genetiv variablity?
Mutations.
Mutations can be a source of genetic .?
Amino Acids.
Can mutations increase the variations in a species' traits?
Yes
What can mutations be a source of?
Mutations create changes in the genetic code. There are different types of mutations and vary in degree of harm or even benefit to the organism. If the mutation happens to be beneficial to the organism, then it can be passed down to its offspring and thus this leads to genetic variation in the population.
What is the importantce of mutations in producing genetic changes in a species?
nothing
What is a source of genetic variation that refers to a random error in the genetic code?
Mutations involve changes in the DNA code.
What causes mutations?
sunlight, radiation, and smoking
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
