Example of Incomplete Dominance - notice how the white and red/brown parent pig colors blended to make the pink pig
This Apaloosa Horse is an example of Codominance. Black and white alleles were neither dominant or recessive so both color are seen in the horse
The image above is a visual representation of typical human chromosomes. Notice the various sizes and shapes! There is an estimated 25,000 genes on these chromosomes that control all of the various human traits.
The diagram below illustrates the relationship between genes and DNA. Genes are segments of DNA found in chromosomes that give the instructions for producing specific traits.

What about alleles?
Gene vs Allele
A gene is a part of the DNA. Alleles on the other hand refer to different versions of the same gene.
- Genes are the different parts of the DNA that decide the genetic traits a person is going to have. Alleles are the different sequences on the DNA-they determine a single characteristic in an individual.
