The pedigree chart given below shows a particular trait which is absent in parents but present in the next generation irrespective of sexes. Draw your conclusion on the basis of the pedigree.

(N/A) The trait is an autosomal recessive trait.
Since the trait is absent in the parents but appears in the offspring,the parents must be heterozygous (carriers) for the trait.
Because the trait appears in both male and female offspring,it is not sex-linked.
Therefore,the inheritance pattern is autosomal recessive,where the genotype of both parents is $Aa$ and the affected offspring have the genotype $aa$.
