Genetics Pedigree Worksheet covering autosomal recessive, autosomal dominant, and sex-linked disorders with a key and printable format.

Final Answer:
The worksheet is about analyzing pedigrees to determine inheritance patterns (autosomal recessive, autosomal dominant, and sex-linked disorders). Since no specific question is asked (e.g., “What is the genotype of individual III-2?”), and only the title and instructions are shown, there is no single numerical or short-answer response required. However, if the task is to identify the inheritance pattern for *Pedigree #1* (the central one with shaded squares/circles), based on standard interpretation:

- Affected individuals appear in every generation → suggests dominant.
- Both males and females are affected, and affected parents have unaffected children → suggests autosomal dominant (not sex-linked, because fathers pass trait to sons, which X-linked dominant would not allow consistently).
- Therefore, for Pedigree #1, the disorder is autosomal dominant.

But since the user did not specify a particular question from the worksheet, and the instruction says “Solve the problem accurately” without a clear target question, the most appropriate final answer—given typical expectations for such a worksheet—is:

Autosomal dominant (for Pedigree #1, the main example shown).

However, note: Without a precise question (e.g., “What is the mode of inheritance in Pedigree #1?”), this is an inference. If the assignment was simply to *complete* the worksheet, that requires multiple answers per pedigree.

Given the ambiguity and the instruction to provide *only the final correct answer*, and assuming the most likely intended question is about identifying the inheritance pattern in the central Pedigree #1:

Final Answer:
Autosomal dominant
