Question

Why do some genes have multiple alleles?

Answer 1

Multiple allelic genes:

1. Genes are the basic functional unit of cells that are crucial for the inheritance of characteristics.
2. Alleles are variations of a single gene that occur on the same chromosome.
3. When a gene contains more than two alleles, it is said to have multiple alleles.
4. Multiple alleles are created when many gene variations of a single gene are present.
5. The multiple alleles combine to generate different phenotypes.
6. Some of the common examples of multiple allelism are blood group in humans, coat color in rabbits, and eye color in Drosophila.
