An autosomal recessive pedigree is a chart that shows the genetic relationships within a family for a specific trait that is inherited in an autosomal recessive manner. In autosomal recessive inheritance, two copies of an abnormal gene must be present for the trait to be displayed. If an individual inherits only one copy of the abnormal gene, they are considered carriers of the trait but do not show any symptoms. Autosomal recessive traits often skip generations and can affect both males and females equally.
Interpreting an autosomal recessive pedigree chart involves looking at the patterns of inheritance within a family. In the chart, individuals are represented by symbols that indicate their gender, whether they are affected by the trait, and if they are carriers. Affected individuals are typically shaded in, carriers are denoted by a half-shaded symbol, and unaffected individuals are left unshaded. By analyzing the relationships between affected individuals, carriers, and unaffected individuals, one can determine the likelihood of passing on the trait to future generations.
