Albinism is a genetic condition characterized by a lack of pigment in the skin, hair, and eyes. It is caused by a mutation in one of several genes that are involved in the production of melanin, the pigment that gives color to these tissues. Albinism can be inherited in an autosomal recessive or autosomal dominant manner.
The pedigree chart below illustrates how albinism is passed down through generations within a family. The chart shows the inheritance patterns of albinism, including the chances of individuals being carriers or affected by the condition.

Interpreting the Pedigree Chart
In the pedigree chart, squares represent males, circles represent females, shaded symbols represent individuals with albinism, and half-shaded symbols represent carriers of the condition. A horizontal line connecting a male and female indicates a mating pair, while vertical lines descending from the pair represent their offspring.
By analyzing the pedigree chart, we can see how albinism is inherited within the family and track the transmission of the genetic trait from one generation to the next. Understanding the inheritance patterns of albinism can help individuals and families make informed decisions about genetic counseling and family planning.
