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 do mutations relate to traits?
Mutations cause certain traits.
Why are there variations in organisms produced by the same parents?

How do helpful variation accumulate in a species over time?
Helpful variations accumulate in a species over time by selecting those traits that allow it to better live in the environment it is in.
Why do variations occur?
Variation or traits are due to changes in the genes. The genes are found in the DNA and when they replicate, the process doesn't always work correctly. We have called these mutations. A few are positive for the species, some are negative (and are not passed on) and a few do not make any change at all.
Can mutations increase the variations in a species' traits?
Yes
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.
Why are mutations are important for evolution?
Mutations serve up the variations in organisms to natural selection. The reproductively successful variations pass on these successful traits to progeny and allele frequencies change because of this and this is evolution.
What are the differences in inherited traits between members of a species called?
variations
How do mutations relate to traits?
Mutations cause certain traits.
How does natural selection affect variation?
Variation naturally occurs in populations as new traits arise from random mutations. However, through natural selection only those traits that are beneficial to the organism are passed on to the next generation. Any harmful mutations are naturally weeded out.
How does dna affect heredity?
DNA carries the genetic information that is passed down from parents to offspring, determining traits and characteristics inherited from each parent. Genetic variations in DNA contribute to the diversity of traits observed in individuals within a species. Mutations in DNA can also lead to new hereditary traits or genetic disorders.
How do new traits arise to create genetic variability?
Random mutations of DNA happen and these get inserted into the gene pool as the species breed.
How helpful variations accumulate in a specie over time?
Helpful variations accumulate in a species over time by selecting those traits that allow it to better live in the environment it is in.

How does variation lead to evolition?
Variation is caused by new genetic mutations in a population which lead to different traits in a population. Evolution selets the most useful of these mutation, eventually leading to prominence of new traits within a species or population, or even new species.
How do helpful variation accumulate in a species over time?
Helpful variations accumulate in a species over time by selecting those traits that allow it to better live in the environment it is in.
