1. Model organisms are species that are studied to understand the biology of other organisms‚ usually humans. Fruit flies share 75% of the genes that cause certain diseases with humans. Therefore scientists can learn about human genetics by studying fruit fly genetics. This falls under the bigger principle of understanding the basic biology that all organisms have in common. Common fruit flies like Drosophila are useful when studying genetics for several reasons‚ such as their small size that makes
