The scientist started to study relationships among various groups of organisms <u>C. by using genetic analyses</u>.
<h2>Explanation:</h2>
The following features were used to study about the relationships between different groups of organism:
External morphology
Similarities in structure
Genetic analysis
Chemical composition
The molecular similarities in the structure of RNA, DNA, and proteins help to establish the relationship of relationships between different groups of organisms. This was studied through testing the samples obtained by organisms using genetic analyses.
What you're looking for is spores. Liverworts, mosses, and hornworts are non-vascular plants the reproduce by forming spores. They are basically little cells that multiply in order to reproduce.
