Which organism has the least number of chromosomes?


What organism has only one chromosome?

(Recall that the number of sets is called the ploidy or ploidy level.) In essentially diploid taxa, an individual organism with only one chromosome set (n) is called a monoploid to distinguish it from species in which all individuals are normally haploid (also n).

Which organism has most 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 organism has the least 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).

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.

How many chromosomes are in a rat?

Genes have been assigned to 20 of the 22 chromosomes in the rat.

How many chromosomes does a mosquito have?

Mosquitoes is a term used to describe approximately 3,500 species of insect. Mosquitos from the family Culicidae have a diploid number of 2n = 6. This means these mosquitoes have three pairs of chromosomes, or six chromosomes total when the sister chromosomes are counted individually.
