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.

What happens when you have 47 chromosomes?

Humans have 23 pairs of 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 type of chromosomes do earthworms have?

(A) Hermaphrodite worms possess two X chromosomes and two sets of autosomes, while males posses one X chromosome to two sets of autosomes. These chromosomal differences create an X to autosome imbalance in males, and an X chromosome imbalance between the sexes.

Are roundworms haploid or diploid?

All animals have a characteristic number of chromosomes in their body cells called the diploid (or 2n) number.

Diploid numbers of some commonly studied organisms.

Homo sapiens (human) 46
Caenorhabditis elegans (microscopic roundworm) 12

What is the diploid number?

Diploid describes a cell that contain two copies of each chromosome. … Among those, there are two sex-determining chromosomes, and 22 pairs of autosomal, or non-sex, chromosomes. The total number of chromosomes in diploid cells is described as 2n, which is twice the number of chromosomes in a haploid cell (n).
