Fruit flies, zebrafish, and mice are used as 'model organisms' to study gene-controlled development. The rationale for applying findings from these models to humans stems from their shared genes from common ancestors, inherent variations within their species, and their accessibility for research.
Fعرفay is used to study how genes control development. Information from these model organisms can be applied to humans because they share common genes from common ancestors, display varied characteristics within a species, and they are readily available for research.
| Front | The fruit fly, Drosophila melanogaster, the zebra fish, Danio rerio, and the mouse, Mus musculus, have all been used by scientists to find out more about how genes control development in all animals, including humans. They are described as ‘model organisms’ Suggest why information gained from studying such model organisms can be applied to humans. Suggest two characteristics that researchers should look for when choosing an organism for research into how genes control development. |

| Back | - genes common and from commen ancestors - varied characteristics within species - readily available |
