What animal has the smallest number of chromosomes?

Which one has the smallest number of chromosomes?

Chromosome 21 is the smallest human chromosome, spanning about 48 million base pairs (the building blocks of DNA) and representing 1.5 to 2 percent of the total DNA in cells.

What animal has only 23 chromosomes?

Overlap in chromosome numbers do definitely occur. 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.

Which species body cells have the smallest total number of chromosomes?

The preparation and study of karyotypes is part of cytogenetics. 2 for females, males are haploid and thus have 1; smallest number possible. Other ant species have more chromosomes.

What has the largest number of chromosomes?

The organism with the highest chromosome number recorded in to date is estimated to be 1,440 (or 720 pairs) found in the adder’s tongue fern Ophioglossum reticulatum.

Which animal has 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.

Which animal has the 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 animal has 19 pairs of chromosomes?

Lion and tiger have nineteen pairs of chromosomes (38 chromosomes).

Do lions and tigers have the same number of chromosomes?

That means the set of genes present in the organisms may vary and therefore lion, tiger and domestic cat have the same number of 38 chromosomes, their characteristics (like different appearances) are the result of the genes located on the chromosomes.
