True / False Questions

1. Microorganisms do not generally reproduce sexually; therefore, species are usually defined by phenotypic and genotypic similarities.
   TRUE

ASM Objective: 01.05 The evolutionary relatedness of organisms is best reflected in phylogenetic trees.
ASM Objective: 06.04 Because the true diversity of microbial life is largely unknown, its effects and potential benefits have not been fully explored.
ASM Topic: Module 04 Information Flow and Genetics
Blooms Level: 2. Understand
Learning Outcome: 19.01.01 Explain the utility of taxonomy and systematics
