What happens if a pedigree shows x linked recessive inheritance does it also show autosomal recessive inheritance?

No: X-linked recessive inheritance involves asymptomatic females passing a condition to their sons. An example is hemophilia A and B. Usually only males are affected. Autosomal recessive inheritance affects both sexes equally. Two asymptomatic parents can pass a condition to their children 25% of the time on average.

Both parents: Autosomal recessive inheritance means that you have to inherit the gene from both parents. Some examples: cystic fibrosis, sickle cell disease.
