Recessive genes are those that are only expressed when an individual has two copies of the same allele. Dominant genes, on the other hand, are expressed even if an individual has only one copy of the allele.

There are many examples of recessive genes that are only seen when paired with a recessive gene. Some of these include:

* Blue eyes: The gene for blue eyes is recessive to the gene for brown eyes. This means that if an individual has one copy of the brown eye gene and one copy of the blue eye gene, they will have brown eyes. However, if an individual has two copies of the blue eye gene, they will have blue eyes.

* Red hair: The gene for red hair is recessive to the gene for brown hair. This means that if an individual has one copy of the brown hair gene and one copy of the red hair gene, they will have brown hair. However, if an individual has two copies of the red hair gene, they will have red hair.

* Albinism: Albinism is a condition that is caused by a lack of melanin, which is the pigment that gives skin, hair, and eyes their color. Albinism is inherited as an autosomal recessive trait, which means that an individual must have two copies of the albinism gene in order to express the condition.
