Natural variations are variations that are often the result of random mutations, that arise when cells divide during development of new organisms.
When these organisms reproduce, they pass on these variations to their offspring – inheritance of natural variation.
Organisms can vary in size, coloration, ability to fight off diseases and countless other traits. These natural variations and their ability to be inherited makes it possible to survive as a species.

Inheritance is the passing on of the traits (due to gene expressions in the form of proteins called enzymes) from one generation to the next. natural variations could be due to Mendelian pattern of inheritance involving segregation and independent assortment of alleles...gene fomrs on homologous chromosomes in any 'diploid' organism. the natual variations could nbe the mutations in genes.. nucleotides or structure of chromosomes and the number of chromosomes called abberations. and some other reasons due to linkage and incomplete dominance and interacton of genes...called Epistasis. etc..
