The statement that is not true regarding the chromosome theory of inheritance is:

ii) No similarity between genes and chromosomes during inheritance

This statement is not true. The chromosome theory of inheritance proposes that genes are located on chromosomes and that the behavior of chromosomes during cell division and fertilization explains the inheritance patterns of genes. In other words, there is a direct relationship and similarity between genes and chromosomes during inheritance. Genes are specific segments of DNA located on chromosomes, and their segregation and assortment during meiosis and fertilization are fundamental to the principles of inheritance.
