Mention four reasons why Drosophila was chosen by Morgan for his experiments in genetics.

Explanation

**Step-by-Step Text Solution:**

1. **Short Lifespan**: Drosophila melanogaster, commonly known as the fruit fly, has a very short lifespan of about two weeks. This allows researchers to observe multiple generations in a relatively short period, making it easier to study inheritance patterns and genetic variations.

2. **Ease of Cultivation**: Drosophila can be easily grown in laboratory conditions. They require minimal space and resources, which makes them convenient for genetic experiments. Their ability to thrive in controlled environments allows for consistent and repeatable experimental conditions.

3. **High Reproductive Rate**: A single mating of Drosophila can produce a large number of offspring. This high reproductive rate results in a substantial sample size for experiments, which is crucial for obtaining statistically significant results in genetic studies.
