Despite a high morphological similarity, tumors with allelic loss on the short arm of chromosome 1 (1pLOH) are more chemosensitive than those without 1pLOH.
The results of the study showed statistically significant differences in persistence scores, showing that subjects with the blood type A allele were more persistent.
The new combinations of DNA created during crossover are a significant source of genetic variation, and result in new combinations of alleles, which may be beneficial.
Many species within this family have conserved the alleles required to synthesizing muscarine until the present day, with a smaller subset of living genera within this family to lose this trait.
