What Type of Genetic Studies Were Conducted By Thomas Hunt Morgan With Fruit Flies?

1. Thomas Hunt Morgan conducted genetic studies on fruit flies. 2. He was the first to show that genes are located on chromosomes, and that chromosomes have a linear structure. 3. He showed that genes are inherited in a linear fashion. 4. He discovered that mutations can occur in genes, and that some mutations are beneficial while others are harmful. 5. He showed that some mutations are beneficial while others are harmful. 6. He developed the concept of gene linkage: the idea that genes tend to be inherited together during meiosis because they are located near each other on homologous chromosomes with similar genetic makeup (i.e., they are linked). 7. He showed that genes assort independently during meiosis: this means that each gene will tend to pair with another gene from its own chromosome during meiosis, not necessarily with its own kind (i.e., two alleles of different genes may end up paired together). 8. He discovered crossing over between homologous chromosomes: this involves exchanges of genetic material between homologous chromosomes during meiosis which can lead to new combinations of alleles within gametes; it results in offspring who receive different combinations of alleles than their parents did! 9. He developed the concept of genetic recombination: his work
