1900 German botanist Carl Correns conducts experiments on Zea mays, commonly known as corn or maize. Correns confirms the findings of Gregor Mendel, an Austrian monk, regarding the principles of inheritance and genetic traits. Mendel's work, initially published in 1866, outlines the laws of inheritance based on his experiments with pea plants. Correns' validation of Mendel's findings with Zea mays provided further evidence for the existence of discrete units of inheritance, which we now know as genes. This confirmation plays a crucial role in the establishment of modern genetics and lays the foundation for understanding heredity in plants and animals.[1] Germany
1902 American biologist William Ernest Castle begins genetic studies on Mus musculus, commonly known as the house mouse. This marks the initiation of systematic genetic research on this species. Castle's work contributes to the understanding of inheritance patterns and genetic variation in mice, laying the groundwork for further investigations into the genetic basis of traits and the mechanisms of heredity. His studies on Mus musculus were instrumental in the development of mouse models for genetic research, which continue to be crucial in biomedical research and the study of human genetics.[2][3] United States
1909 Thomas Hunt Morgan begins his groundbreaking work with the fruit fly Drosophila melanogaster, which would become synonymous with his name. Prior to this, C. W. Woodworth and W. E. Castle had shown interest in Drosophila for genetic studies. Morgan's research with Drosophila would lead to the discovery of sex linkage of the gene for white eyes, demonstrating the phenomenon of linkage. He bred Drosophila in large quantities, facilitating the analysis of spontaneous mutations and the localization of genes. Morgan's work laid the foundation for understanding the linear arrangement of genes in chromosomes and significantly advanced the field of genetics.[4]
