Oct. 16th, 2006 05:07 pmVAVILOV found similar changes or parallel mutations in many closely related species ("The Law of Homologous Series in hereditary Variation", 1920). Summarizing the results of his studies, VAVILOV came to the following conclusions:
1. Genetically closely related species and genera are characterized by similar series of hereditary variation with such a regularity that, knowing the series of forms within one species, one can predict the existence of parallel forms in other species and genera. The genetically closer the genera and Linnaeons within the general system are, the greater is the similarity in the series of their variation.
2. Whole plant families are generally characterized by a definite pattern of variation penetrating all the genera and species comprising a family.
