Allele Vs Gene: Allele is generally a variant form of a gene. In chromosome genes are in different forms located at a same position. Humans are diploid organisms because of the presence of two alleles in which one is inherited from mother and the other from parent. Both Allele and Gene are genetic sequences. Gene is a unit which contains hereditary information except in some viruses while on.
