What role do alleles play in natural selection?
Genes are the medium by which inherited traits are passed on to offspring. It is inherited traits, and thus genes, that receive positive or negative selection.
How does environmental pressure affect natural selection?
When nothing happens to exert strong population pressure on that population, natural selection favors the allele frequency already present. When mutations cause new traits, natural selection weeds these traits out because they're not as efficient as the others.
Which type of natural selection in which the mean characteristics of a population are preserved?
This type of natural selection is called stabilizing selection because the mean traits of the population are being selected for against the immediate environment.
How did Lamarck's ideas differ from Darwin's?
Lamarck believed an individual organism acquired traits during its lifetime and passed those traits on to its offspring. He lacked support for his ideas. Darwin documented how inherited traits could be passed on by natural selection, that adaptations that give an organism an advantage is passed on through subsequent generations and becomes more common. He had evidence for his ideas (finches, tortoises…).
Is inheritance a requirement for natural selection?
Yes it does. Without variance in the organisms genome, that gives variance to the phenotype, there would be nothing for natural selection to select from.
What is the process in which traits are chosen to be inherited in evolution?
Natural Selection
In Natural Selection the advantage of inherited traits depend on?
It depends on the ANIMAL!
Why are only inherited traits not accured ones necessaryn for the process of natural selection'?
Unlike inherited traits, acquired traits are not passed on to the next generation.
What role do alleles play in natural selection?
Genes are the medium by which inherited traits are passed on to offspring. It is inherited traits, and thus genes, that receive positive or negative selection.
Does inheritance of acquired characteristics express the concept of natural selection?
No. Natural selection is the differential reproductive success of varying inherited traits. Acquired traits do little to affect the inheritance of traits, except through epigenetics.
natural selection?
A process in which individuals that have certain inherited traits tend to survive and reproduce at higher rates than other individuals because of those traits.
What factors are responsible for inherited traits in an organism?
The Genes.
What happens to unnecessary traits during the process of natural selection?
How does natural selection affect undesirable traits?
Why does natural selection depend on variations and DNA?
The variations in the DNA are responsible in differences between desirable traits and unwanted traits. Mutations also cause changes in the DNA.
How are artificial selection and natural selection similar?
Natural selection and artificial selection both involve an organism's traits being determined by how much they're favored. Then, the organisms with favorable traits pass those traits on to future generations.However, natural selection is caused by survival; the organisms with traits that increase their chances for survival and reproduction pass on their traits. As for artificial selection, humans purposefully decide which traits (like the most colorful one) of an organism to pass on.The similarity of artificial selection and natural selection is that they both can cause changes in the frequency of population.
What process in which organisims with traits well suited to an environment are more likely to survive and to produce offspring is?
natural selection
What is the process where animal select mates with traits best suited for survival?
natural selection. :)
