Dear Student
You can see that male at III.6 position is affected and he is passing his trait to both sons and daughters.Therefore it is an autosomal trait. If it would have been Sx-Linked then the male can only pass on his trait to daughters.

It is a dominant trait because it is visible in every generation.
Thus we can conclude that it is autosomal Dominant.

In pedigrees, an autosomal recessive disorder is revealed by the appearance of the phenotype in the male and female progeny of unaffected individuals
