About This Dataset
Number of Chromosomes by Species
The number of chromosomes (the diploid count, 2n) carried by different animals. The figure has nothing to do with an organism's size or complexity: a goldfish has more than twice as many chromosomes as a human, while a fruit fly has only eight.
Analysis
The top three in Diploid Chromosome Number (2n) are Goldfish (100), Dog (78) and Chicken (78). Goldfish tops the list without dominating it, holding 23.8% of what the 9 entities record between them. Only 4 of the 9 reach even half the leader's figure (50 or more).
