And there is a wide range of chromosome numbers. Animal chromosome numbers range from 254 in hermit crabs to 2 in a species of roundworm. The fern called Ophioglossum reticulatum has 1260 chromosomes! Humans have 46, chimpanzees have 48, and yes, potatoes also have 48.
What animals have 46 chromosomes?
List of organisms by chromosome count

Do all organisms have 46 chromosomes?
All organisms do not have the same number of chromosomes. For example, human cells have 46 chromosomes, each whereas dogs have 39 chromosomes in each…
Do dogs have 46 chromosomes?
Each chromosome contains hundreds or thousands of different genes. Chromosomes are found in pairs within the cell. Each cell contains two separate copies of each gene (alleles). While a human has 46 chromosomes (23 pairs), a cat has 38 chromosomes (19 pairs) and a dog has 78 chromosomes (39 pairs).
Which animal has 23 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. Are you ready for something really weird, though? A different subspecies of this same deer has only three pairs!
Which animal has lowest number of chromosomes?
To date, the organism with the least number of chromosomes is the male Australian ant, Myrmecia pilosula, with one chromosome per cell (male ants are generally haploid—that is, they have half the number of normal chromosomes while the female ant has two chromosomes per cell).
What if a person has 47 chromosomes?
A trisomy is a chromosomal condition characterised by an additional chromosome. A person with a trisomy has 47 chromosomes instead of 46. Down syndrome, Edward syndrome and Patau syndrome are the most common forms of trisomy.
What happens if you have 45 chromosomes?
There are 2 types of Turner syndrome: monosomy X TS and mosaic TS. About half of all girls with Turner syndrome have a monosomy disorder. Monosomy means that a person is missing one chromosome in the pair. Instead of 46 chromosomes, the person has only 45 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.
Who has more chromosomes a dog or a human?
Humans have 46 chromosomes (23 pairs), dogs have 78 chromosomes (39 pairs), cats have 38 chromosomes (19 pairs), and so on. Domestic dogs have the same number of chromosomes as coyotes, dingoes, jackals, and wolves.
Can a dog have Down syndrome?
Simply put, the answer is no. The condition of Down syndrome has not been described in dogs. Three explanations are possible: These types of chromosomal abnormalities typically lead to early death in dogs.
How many chromosomes do dogs have in a sperm cell?
There are 39 chromosomes in a dog sperm cell and 39 chromosomes in a dog egg cell. When combined they have a total of 78 chromosomes.
