This pedigree doesn't show an autosomal dominant trait because 3,4 are carriers, passing the gene to their offsprings but don't manifest the phenotype. This pedigree can represent an autosomal recessive gene based on what I just mentioned. We know that this is an autosomal trait because it seems to affect both genders equally.
