What is the difference between allele and character traits?

Allele is an alternative form of a gene which influences the phenotypic expression of the gene. Character trait is a physical expression of the gene.

Differences between allele and character traits:

Allele	Character trait
Alleles are the alternative forms of genes.	Character trait is the physical expression of the gene.
Allele is in a specific location in the chromosome.	Character trait is a physical expression and so, does not have any location on the chromosome.
Allele may be in homozygous state or heterozygous state.	Character trait does not have homozygous or heterozygous state.
Allele is a small segment of DNA.	Character trait is a product of biochemical reactions.
Alleles carry information which is responsible for a trait of an individual.	Character trait is a characteristic of an individual.
