Which animal has highest number of chromosomes?

How many chromosomes does a chimpanzee have?


Humans have 46 chromosomes whereas chimpanzee gorilla and orangutan have 48. This major karyotypic difference was caused by the fusion of two ancestral chromosomes to form human chromosome 2 and subsequent inactivation of one of the two original centromeres (Yunis and Prakash 1982).

Males with XXYY syndrome have 48 chromosomes instead of the typical 46. This is why XXYY syndrome is sometimes written as 48 XXYY syndrome or 48 XXYY. It affects an estimated one in every 18 000–40 000 male births.
