If every generation shows the trait, it suggests that the trait is passed down from affected parents to their offspring in a dominant manner. This means that individuals with only one copy of the dominant allele will express the trait, whereas individuals with two copies of the recessive allele will not. This pattern is consistent with a dominant inheritance pattern. The fact that the trait is present in every generation suggests that it is not sex-linked, as sex-linked traits often skip generations depending on the sex of the affected parent.
