Autosomal dominant

Vedclass · Answer

(B) $1$. Observe the pedigree: The trait appears in every generation (vertical transmission), which is characteristic of a dominant trait.$2$. Check for sex-linkage: An affected mother has an unaffected son, and an affected father would pass the trait to all daughters if it were $X$-linked dominant. Here, an affected mother has an unaffected son, which is possible in both autosomal and $X$-linked dominant traits. However, the transmission from an affected mother to both sons and daughters, and the presence of the trait in both sexes, strongly suggests an autosomal dominant pattern.$3$. Conclusion: Since the trait does not skip generations and appears in both males and females, it is autosomal dominant.

In a practical examination, the pedigree chart shown below was provided for identification. Identify the type of inheritance.
