There often isn’t a relationship between number of chromosomes and number of genes. For example, we have 46 chromosomes while the simple goldfish has 94 and the toucan has 106! … They have a different number of chromosomes only because one of the human chromosomes is essentially the same as two chimpanzee chromosomes.

Which animal has the highest number of chromosomes?
The mitotic and meiotic chromosomes of the semiaquatic rodent Ichthyomys pittieri (Rodentia, Cricetinae) from Venezuela were analyzed by means of conventional staining and several banding techniques. The diploid chromosome number of this rare species is 2n = 92, which is the highest value known for mammals.
