Which organism is commonly used in genetic studies for its simple inheritance patterns?

Drosophila, commonly known as the fruit fly, is widely used in genetic studies due to its simple inheritance patterns and the ease with which it can be bred in the laboratory. It has a relatively short life cycle, allowing researchers to observe multiple generations in a short amount of time. The genetic makeup of Drosophila is also well-understood, and many mutations and traits have been documented, making it an ideal model organism for studying heredity and genetic variation.

In addition, Drosophila has a manageable number of chromosomes, making it easier to track specific traits and their inheritance patterns. Its use in research has contributed significantly to our understanding of key genetic concepts, such as gene linkage, chromosome mapping, and the role of specific genes in traits and diseases. Researchers appreciate the ability to conduct controlled breeding experiments and analyze results quickly, solidifying Drosophila's status as a cornerstone in genetic research.

While Arabidopsis is also used in genetic studies, particularly in plant genetics, and Escherichia coli serves as a fundamental model for understanding bacterial genetics, they do not offer the same straightforward inheritance analysis as Drosophila. Gallus gallus, or the domestic chicken, is studied in genetics but on a different scale
