Autosomal dominant trait

Vedclass · Answer

(A) The correct answer is $A$ (Autosomal dominant trait).$1$. Analysis of the pedigree shows that the trait appears in every generation (it does not skip generations),which is a characteristic feature of a dominant trait.$2$. Affected individuals have at least one affected parent.$3$. The trait is observed in both males and females,and affected mothers pass the trait to both sons and daughters,which rules out sex-linked recessive inheritance.$4$. Since an affected mother passes the trait to her offspring regardless of their sex,and it does not show the specific pattern of criss-cross inheritance,it is identified as an autosomal dominant trait.

In the given pedigree chart,which Mendelian disorder is represented?
