Which causes more variation within a population from generation to generation mutation or sexual recombination and Why?

Sexual recombination only takes genes already extant and make new combinations.
Mutation presents a brand new variation ( if not neutral or deleterious ) to the eye of natural selection. So, mutation, from generation to generation.

What constantly provides new variation for natural selection to act upon in a sexually reproducing popularion?
Firstly, mutation. In a sexually reproducing population recombination ( independent orientation of chromosomes and crossing over in meiosis and random fertilization ) is also a source of variation in populations.
Is natural selection a source of variation within species?
No, mutation and sexual recombination are the sources of variation and natural selection selects from those variations presented to it against the immediate environment.
What is the relationship between mutation rates and generation span?
The relationship between mutation rates and generation span is that they both have in impact on the Mitochondrial DNA diversity patterns,unexpected variation of mutation rate across species
Is homologous recombination a type of mutation?
No. A mutation can change an allele into any other allele. Homologous recombination can only change an allele to the allele of the homologous chromosome.
Is the only possible source of new genetic material?
mutations recombination/crossing over in mammals
What are the main sources of heritable variation in a population?
mutations, recombination, random pairing of gametes
What are two main sources for genetic variation in a population?
Mutation and the genetic recombination in sexually reproducing organisms.
What are the two main sources for variation?
Mutation and sexual recombination.
What are two sources of genetic variation?
Natural and Artificial Selection

What will make population have more genetic variation?
mutation
What provides the source of variation in evolution?
Mutation, such as insertion, deletion and rarely frameshift mutation. Sexual recombination, is sexually reproducing species. This includes, in meiosis, the independent assortment of chromosomes and crossing over. Then there is random fertilization to provide a last source of variation.
What is the primary original source of genetic variation in a population?
Go to the link below, it has a lot of information on variation in population.
What is the relationship between mutation rates and generation span?
The relationship between mutation rates and generation span is that they both have in impact on the Mitochondrial DNA diversity patterns,unexpected variation of mutation rate across species
Which two processes result in variations that commonly influence the evolution of sexual reproducing species?
mutation and genetic recombination.
What process provides the genetic variability that natural selection acts on during evolution?
The ultimate source of variation is mutation. However, recombination, or crossing over, can produce enormous amounts of variation by shuffling alleles into different combinations. Combined, the two processes produce the variation upon which natural selection can act, and which results in evolution.
