what is chromosomal theory of inheritance

The chromosomal theory of inheritance, also known as the Boveri-Sutton chromosome theory, is a fundamental theory of genetics that identifies chromosomes as the carriers of genetic material. It explains the mechanism underlying the laws of Mendelian inheritance by identifying chromosomes as the structures that contain genes, the units of heredity. This theory states that genes are found at specific locations on chromosomes, and the behavior of chromosomes during meiosis can explain Mendel’s laws of inheritance. The theory was proposed by Walter Sutton and Theodor Boveri in the early 1900s and was later supported by Thomas Hunt Morgan's experiments with fruit flies, which provided evidence for the idea that genes are located on chromosomes
