Given the pedigree below, what is/are the most likely inheritance pattern(s)? Patterns are autosomal recessive, autosomal dominant, X-linked recessive, X-linked dominant or Y linked. Justify your choices.
Understand the Problem
The question is asking to analyze a given pedigree chart to determine the most likely inheritance patterns for a trait, with options including autosomal recessive, autosomal dominant, X-linked recessive, X-linked dominant, or Y-linked. Justification for the choices is also required, indicating an understanding of genetic inheritance patterns.
Answer
Autosomal recessive
The most likely inheritance pattern in the given pedigree is autosomal recessive.
Answer for screen readers
The most likely inheritance pattern in the given pedigree is autosomal recessive.
More Information
Autosomal recessive traits often appear when two carriers have children, leading to roughly equal numbers of affected males and females, without skipping generations from affected individuals.
Tips
A common mistake is overlooking unaffected parents having affected children, which suggests recessive inheritance rather than dominant.
