In humans, there are 23 chromosomes, and we have two of each, meaning we each carry 46 of them. In both goldfish and the carp they were derived from, there are 25 chromosomes, but each fish carries 100 of them—instead of two copies, they have four, or rather two sets of two.
Do fish have XY chromosomes?
Multiple sex chromosome systems in fishes
Most species with sex chromosomes either have a simple male heteromorphic (XX female/XY male) or female heteromorphic (ZW female/ZZ male) system.
What are fish chromosomes?
Fluorescence in situ hybridization (FISH) is a molecular cytogenetic technique that allows the localization of a specific DNA sequence or an entire chromosome in a cell.
How many chromosomes are in a salmon?

Is there an animal with 92 chromosomes?
Abstract. 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.

How many chromosomes does a snake have?
The vast majority of snakes have diploid numbers (2n) of 36 chromosomes, containing 16 macrochromosomes and 20 microchromosomes [19,20]. However, variations involving macro and micro karyotypic structure and a diploid number have also been reported in different families across snake lineages [21,22,23,24,25].
