Mendeleev organized the chemical elements based on their properties.
Mendeleev put elements in order in the periodic table according to their physical and chemical properties. He noticed that properties of elements were related to their atomic mass in a 'periodic' way, so he groups of elements with similar properties into vertical columns in the table. His periodic table had initial 63 elements which then expanded to 108 or 109 elements.
The answer is genetic diversity, Genetic diversity is the
total number of genetic features in the genetic makeup of a species. It is well-known
from genetic variability, which defines the tendency of genetic characteristics
to vary. Genetic diversity serves as a way for populations to adapt to changing
environments.
