Most fishes have between 40 and 60 chromosomes, with 48 a generally accepted number for some common ancestral fish.
Which fish has most chromosomes?
The highest chromosome count of any vertebrate to date (2n ~ 446) was documented in Ptychobarbus dipogon, a cyprinid fish from the Tibetan Plateau. Critically endangered sturgeons, having undergone three whole genome duplication events, represent an exceptional example of ploidy plasticity in vertebrates.

Humans have 23 pairs of chromosomes, for a total of 46 chromosomes. In fact, each species of plants and animals has a set number of chromosomes.

How many chromosomes do sturgeon have?
Chromosomes of octoploid Siberian sturgeon. (a) Metaphase spread obtained from leucocyte culture of functionally octoploid Siberian sturgeon counting 501 chromosomes; (b) Corresponding karyotype composed of 200 metacentric/submetacentric chromosomes, 96 acrocentric/telocentric chromosomes, and 205 microchromosomes.
What is the total chromosome count for the sturgeon fish?
The karyotype of the Siberian sturgeon (Acipenser baerii) contains around 250 chromosomes and is remarkable for the presence of paralogs from two rounds of whole-genome duplications (WGD).
How many chromosomes does a strawberry have?
The strawberry genus, Fragaria (Rosaceae), has a base chromosome number of x = 7. Cultivated strawberries (F. ×ananassa nothosubsp. ananassa) are octoploid (2n = 8x = 56) and first hybridized from F.
How many chromosomes do jellyfish have?
Eighteen Genes: Eight Chromosomes.
How many chromosomes do monkeys have?
Monkeys usually have 48 chromosomes. This number of chromosomes is greater than the number possessed by humans by two. This is because in recent evolution of the human lineage, there was a chromosome fusion event. This joined two chromosomes lowering the number of chromosome pairs from 24 to 23 in humans.
What animal has 76 chromosomes?
In humans, two of those chromosomes are sex chromosomes a fact oddly shared with dogs (Canis lupus familiaris) who, however, have 76 autosomal chromosomes to the human 44. These numbers hardly reach the highest in the Animal Kingdom, with the Agrodiaetus butterfly at 268.
Which animal has 23 pairs of chromosomes?
Potatoes and Chimpanzees, for example, both have 24 pairs of chromosomes. Humans are not the only animal with 23 pairs, either–the Chinese subspecies of Muntiacusmuntjac, a small kind of deer, also has 23 pairs of chromosomes.
How many chromosomes do dolphins have?
The karyotype of the bottlenosed dolphin and the pilot whale have been described and compared from a karyological evolutionary point of view. Both species have 44 chromosomes and the two chromosome complements are strikingly similar.
Can humans breed with any other animals?
Probably not. Ethical considerations preclude definitive research on the subject, but it’s safe to say that human DNA has become so different from that of other animals that interbreeding would likely be impossible. In general, two types of changes prevent animals from interbreeding.
What chromosomes did Jesus have?
Being fully human, Jesus had normal appearing human chromosomes – so a paired set of 22 autosomes and an X and Y (note that Dylan refers to “alleles” in his question.
Can you have 48 chromosomes?
Boys and men with 48,XXXY syndrome have the usual single Y chromosome, but they have three copies of the X chromosome, for a total of 48 chromosomes in each cell. Boys and men with 48,XXXY syndrome have extra copies of multiple genes on the X chromosome.
How many chromosomes do Kiwis have?
The kiwifruit species are often reticulate polyploids with a basic chromosome number of x = 29 (5).
How many chromosomes do elephants have?
56 Organism # of chromosomes Human 46 Elephant 56 Woolly Mammoth 58 Kangaroo 16.
How many chromosomes does a mango have?
Mango has a total of 40 chromosomes, which suggests a haploid number of chromosomes as 20 and similarly 20 linkage groups. The haploid genome size is estimated at ~439 Mb (Arumuganathan and Earle, 1991).
How many chromosomes does a shark have?
Feb 19, 2019. The great white shark genome—like the animal itself—is giant, with 41 pairs of chromosomes compared to humans’ 23 pairs, researchers reported yesterday (January 18) in PNAS.
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].
How many chromosomes does a tiger have?
Panthera tigris has 38 chromosomes. The karyotype has 16 pairs of metacentric and submetacentric autosomes and two pairs of acrocentric autosomes.
How many chromosomes does a donkey have?
(A horse has 64 chromosomes and a donkey has 62). To understand why this is a problem, we need to understand how sperm and eggs are made.
How many chromosomes do pigs have?
In the normal cell of a pig, or any mammal, chromosomes occur in distinct pairs. Pigs have 19 chromosome pairs for a total of 38 chromosomes (Figure 1). This contrasts with humans, who have 23 chromosome pairs for a total of 46.
How many chromosomes do frogs have?
A body cell from a frog has 26 chromosomes.
What happens if you have 45 chromosomes?
Turner syndrome (TS), also known as 45,X, or 45,X0, is a genetic condition in which a female is partially or completely missing an X chromosome. Signs and symptoms vary among those affected.
What animal has 60 chromosomes?
The goat (Capra hircus) also has a chromosome number of 60 (Sokolov, 1930; Shiwago, 1931). The chromosomes of the goat were recently studied by Basrur and Coubrough (1964), who found all chromosomes to be acrocentric.

An ostrich’s eye is bigger than its brain, and is the largest eye of any living land animal, measuring five centimetres across.
