In his experiments, Mendel noted that when two traits are involved in a genetic cross, they are inherited independently of each other. The reason for this is that A. genes on the same chromosome separate during the formation of gametes. B. alleles on the same gene separate during the formation of gametes. C. genes on different chromosomes separate during the formation of gametes. D. alleles on the same chromosome separate during the formation of gametes. E. chromosomes often recombine.
