Final answer:
The correct answer is E. large genome, which is generally not a desirable characteristic for a model organism in development studies, as it can complicate and slow down research compared to organisms with smaller genomes.
Step-by-step explanation:
In the context of model organisms used to study development, a desirable characteristic is typically something that allows for efficient and controlled study of biological processes. The question asks which of the following is NOT a desirable characteristic:
- short generation time
- small size
- large oocytes
- produces many offspring
- large genome
Answer: E. large genome.
A large genome is generally not a desirable characteristic because it can complicate genetic studies and slow down research progress. Model organisms with large genomes require more resources for genetic analysis and can become more difficult to manipulate genetically. In contrast, organisms with smaller genomes are easier to work with in laboratory settings, making them preferable for developmental studies. Therefore, a large genome is not a desirable characteristic for a model organism used in developing studies.
