👉 A chromophilous organism is an organism that has a chromosome that contains only one set of chromosomes. This means that the chromosome has two copies of each gene, and those genes are located on different chromosomes. The cell cycle of this type of organism is not regulated by the mitotic spindle fibers, which can be found in other types of chromophilous organisms. Chromophilous organisms have a unique genetic code that allows them to reproduce without the help of the mitotic spindle fibers, allowing them
