Characteristics of multiple alleles 

1. Multiple alleles are present at definite position on the same locus in the chromosome.

2. Crossing over does not occur in multiple alleles.

3. The normal (wild) allele is always dominant over the multiple alleles.

4. The multiple alleles follow mendelian principles of segreation and assortment.

5. When two individuals are crossed together with multiple alleles one of them will show dominance.
