Autosomal dominant

Vedclass · Answer

(A) To determine the mode of inheritance from the pedigree chart:$1$. Observe that an affected mother (filled circle) and an unaffected father (empty square) produce both affected sons and affected daughters.$2$. Since the trait appears in every generation and affected individuals have at least one affected parent,it is a dominant trait.$3$. If it were $X$-linked dominant,an affected father would pass the trait to all his daughters,which is not observed here. Also,an affected mother would pass it to all her sons,but here she has an unaffected son as well.$4$. The pattern of inheritance where an affected mother passes the trait to both sons and daughters,and the trait does not skip generations,is characteristic of Autosomal Dominant inheritance.$5$. Therefore,the correct option is $A$.
