Vedclass · Answer

(B) $1$. Analyze the pedigree: The trait appears in every generation (vertical transmission),which is characteristic of dominant traits.$2$. Check for Autosomal Dominant inheritance: In autosomal dominant traits,an affected individual must have at least one affected parent. Here,the affected individuals in generation $II$ and $III$ have affected parents.$3$. Check for $X$-linked dominant: If it were $X$-linked dominant,an affected father would pass the trait to all his daughters. In generation $I$,the affected father has an unaffected daughter in generation $II$,which rules out $X$-linked dominant.$4$. Conclusion: The pattern is consistent with Autosomal Dominant inheritance,as it does not skip generations and affected individuals have affected parents.

In the given pedigree chart,the filled symbols represent affected individuals. Identify the type of inheritance:
