One type of natural transmutation observable in the present occurs when certain radioactive elements present in nature spontaneously decay by a process that causes transmutation, such as alpha or beta decay. An example is the natural decay of potassium-40 to argon-40, which forms most of the argon in the air.
After all, the farther apart two genes were on a chromosome, the more likely it was that these genes would separate during recombination. Therefore, as Sturtevant explained it, the proportion of crossovers could be used as an index of the distance between any two factors (Sturtevant, 1913).igure 2: Allele recombination. Recombination is the sorting of alleles into new combinations. Following the formation of gametes over two generations shows how recombination can produce new allelic combinations (lower right) or stay the same (lower left).
