  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.  

Answer:

                      The pedigree chart shows that the trait is auto some linked and recessive in nature. But, the parents are carriers (i.e., heterozygous) hence, among the off springs only few show the trait irrespective of sex. The other off springs are either normal or carrier.
