Without genetic variation, the mechanisms of evolutionary change will not occur. There are several sources of genetic
variation within a breeding population: sexual reproduction, mutation, and gene flow. Illustrated here is a key
component of two of the three sources of genetic variation: recombination. How does recombination contribute to
evolution?
A)
B)
The exchange of genetic information during meiosis results in the
formation of new alleles.
During recombination, homologous chromosome exchange pieces of
genetic information, increasing genetic variability.
Once reproduction has occurred, chromosomes exchange pieces of genetic
information, resulting in a new set of chromosomes.
During recombination, homologous chromosome exchange pieces of
genetic information, creating mutations that drive evolutionary change.
