The main difference between Gene and Allele: A gene is a segment of DNA that codes for a specific protein or trait, while an allele is a variant form of a gene. Different alleles of the same gene can
Gene vs Allele — Comparison Table
| Basis | Gene | Allele |
|---|---|---|
| Definition | DNA segment coding for a specific protein | Different form or variant of a gene |
| Number Per Trait | One gene codes for a trait | Multiple alleles can exist for one gene |
| Location | Fixed location on chromosome | Same location as the gene on chromosome |
| Function | Controls development of a trait | Controls different versions of the same trait |
| Example | Gene for eye color on chromosome 15 | Alleles for brown, blue, green eye colors |
| Origin | Passed from parents to offspring | Different versions inherited from both parents |
Key Points
- A gene is the unit of heredity while alleles are alternative forms of that gene
- Each organism inherits two alleles for each gene, one from each parent
- Dominant alleles mask recessive alleles in expression
- Variation in alleles creates genetic diversity in populations
