Final answer:
Human beings, Homo sapiens, are NOT a model genetic organism used in biological research because of ethical considerations and research complexity. Other options like Saccharomyces cerevisiae, Drosophila melanogaster, Caenorhabditis elegans, and Arabidopsis thaliana are established model organisms utilized for their research advantages.
Step-by-step explanation:
The model genetic organism that is NOT listed among commonly used model organisms for genetic research is c. human beings, Homo sapiens. Other options provided, such as a. budding yeast, Saccharomyces cerevisiae; b. fruit fly, Drosophila melanogaster; d. worm, Caenorhabditis elegans; and e. herbaceous plant, Arabidopsis thaliana, are all well-established model organisms in biological research. These model systems are often chosen for their ease of care, short life cycles, and the simplicity of their genomes, which makes them amenable to genetic studies and allows scientists to draw parallels to human biology. In contrast, while human beings are of course extremely relevant to human biology, they are not used as model organisms due to ethical considerations and the complexity of human research.
