Generally, complex organisms do require more genes to control their synthesis and organization than do primitive organisms. However, the numbers of chromosomes vary from ants with 2, molds with 8-14, humans with 46, potatoes with 100 and the crayfish with 200! Some birds and insects have chromosomes that dwindle in size into obscurity, so it is not possible to establish a diploid number. How do you explain this situation?
A) There must be no relationship between amount of genetic information and complexity of the organism.
B) The number of genes per chromosome may vary among organisms, preventing a simple relationship between chromosome number and complexity.
C) Birds and insects probably cannot follow the same mitotic laws as other organisms.
D) All of the choices are correct.

The number of genes per chromosome may vary among organisms, preventing a simple relationship between chromosome number and complexity. Essentially, the organization of genetic information differs among organisms, so it is not possible to establish a direct relationship between chromosome number and complexity.
