Is the theory of linked inheritance confirmed cytologically?

Yes. Genes are located on the chromosomes. In the process of cell division, chromosomes diverge to the poles of the cell as a whole, therefore, all alleles located on the same chromosome must be inherited linked. However, in the process of meiosis, crossover and the exchange of genetic material occurs between homologous chromosomes, which disrupts the linkage of inheritance of alleles.
