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.
Mutations are a source of what in a species?
Genetic variation, which can lead to evoloution, and then potentially a new species.
True or false Mutations can increase the variations in a species 'traits?
Mutations are important for evolution because they provide the variability whereupon natural selection acts.true last answered by zaporia
Is evolution good or bad?
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.
How can genetic mutations support macro-evolution?
Mutations in an individuals germ line can be passed into progeny and if these mutations are beneficial then the allele frequency in the individuals population can change which is evolution. Over time and with many beneficial mutations against a favorable environment a population, or populations, most often geographically isolated, can change alleles so much that the two split populations can no longer interbreed and you have a new species; macro-evolution.
What are the evolutionary values of mutations?
Mutations have allowed species to adapt the their environment.
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.
Which statement is not included as a part of the modern theory of evolution?
sexual reproduction and mutations provide variation among species
Can the genetic mutations from older fathers accelerate physical and intelligence increase consistent with genetic mutations and evolution of the human species?
Doubtful. Aside from a fluke copying error the mutations in germ line cells of the older father are, statistically, much more likely to be deleterious in nature, swamping any beneficial mutations along for the ride.
Which two factors provide the genetic basis for variation within a species?
mutations and sexual reproduction (due to random orientation of bivalents about the equatorial spindle during metaphase I and pairs of chromatids during metaphase II; fusion of male and females gametes during fertilization; and reciprocal crossing over)
How can Darwinain evolution be true if more than 99 percent of genetic mutations are retrogressive?
Darwinian evolution works very slowly over hundreds of generations. Though 99percent of mutations may be lost through natural selection the remaining 1 percent positive mutations will eventually, given sufficient time, improve the fit of the species to it's environment.
How do genomes of species change?
By mutations in DNA.
