उत्तर
As we go from species to kingdom in a taxonomic hierarchy, the number of common characteristics will decrease.
Explanation:
As we go higher from species to kingdom, the number of common characteristics goes on decreasing. The lower the taxa, the more the characteristics that the members within the taxon share. The higher the category, the greater the difficulty of determining the relationship to other taxa at the same level.
