General Quiz 3 First Secondary On Genetics And Classification - Quiz

Are you ready for this general quiz on genetics and classification? For this quiz, you should understand the difference between genus, class, and species, what the term family but different species means, what phylum does a soft-bodied, invertebrate animal belong to, what is a unicellular organism, and what is used to determine the phyla that a plant belongs. This quiz will clarify the first secondary classification for you. Good Luck.
