Creationary biologists have recognized that the diversity seen within created kinds today cannot be adequately explained by the shuffling of pre-existing gene versions (alleles) and accidental errors that accumulate within the genome.1 Within the context of creation, the development of genetic diversity has been a means by which God has enabled his creatures to adapt to the many different environmental niches they occupy today (Genesis 1:22; 8:17; Isaiah 45:18). Further, it has played an important role in adding variety, beauty, and productivity in various domesticated plants and animals.2

There is certainly no logical reason to believe that unguided chance processes can bring about a functional genome.3 Neither is there sound reason to believe that accidental changes to the genome are a productive source of useful genetic diversity. Logically, therefore, the genome must contain biological information that allows it to induce variation from within.4 One mechanism involved in this is meiotic recombination.5 Continued scientific research is elucidating some amazing details of this process.

Meiosis is a special type of cell division necessary for the formation of gametes (eggs or sperm) so sexual reproduction can take place. In most plants and animals, chromosomes come in pairs (homologs, one derived from each parent), but gametes only carry one of each homolog. Early in meiosis, each chromosome must be drawn to its homolog and stably pair. Then each homolog will be pulled in the opposite direction so that the two cells that form during the division will have exactly one of each homolog.

Meiotic recombination is no accident
