7. In the given pedigree skip of generation is seen. The parents II-3 and II-4 do not show the trait but one of their children i.e. III-1 shows the trait. It indicates that parents are heterozygous and the trait is recessive. If the the trait was dominant then there will be no skip of generation. Since a skip of generation is seen, it indicates that it is a recessive trait.
So, the correct alternative is option-3; "The observed trait is recessive because it skips a generation of expression."
