Final answer:
Yes, all model organisms have relatively short reproductive life cycles which allows for rapid evolution and easy observation of developmental and age-related phenomena.
Step-by-step explanation:
Yes, all model organisms have relatively short reproductive life cycles. This means that they complete their reproductive cycle in a very short period and produce a large number of offspring. For example, the common fruit fly, Drosophila melanogaster, has a short generation time and can produce many offspring in a short period. This short reproductive life cycle is advantageous for research purposes as it allows for rapid evolution and easy observation of developmental and age-related phenomena.
