Web2.3 Two Loci on One Chromosome. Based on the description in the last section, it would be expected that if the genes were on the same chromosome the alleles would travel together through meiosis ( Figure 2.3.1 top). However, when tested this is not always the case. The recombination of alleles can be explained through the phenomenon of crossing ... WebDNA contains long chains of chemicals called bases.
