The three sources of variation in a population that natural selection can work on are:
A) Mixing together of parental genes, recombination and gene mutations
B) Modifier genes, recombination and gene mutations
C) Mixing together of parental genes, modifier genes and recombination
D) Gene mutations, mixing together of parental genes and linkage

Question

Quizplus · Accepted Answer

Mixing together of parental genes through sexual reproduction, recombination of genes during meiosis, and gene mutations are the three sources of genetic variation that natural selection can act upon. Modifier genes and linkage are also important factors in evolution but do not fall under the three sources of variation mentioned in the question.
