Question: What Organism Has The Most Chromosomes?

What organism has the most genes?

water flea DaphniaThe tiny water flea Daphnia has the most genes of any animal, some 31,000.

Scientists have discovered that the animal with the most genes–about 31,000–is the near-microscopic freshwater crustacean Daphnia pulex, or water flea.

By comparison, humans have about 23,000 genes..

How many chromosomes do banana have?

11 chromosomesThis is the first completed sequence of the 11 chromosomes of banana and it provides the first detailed genetic blueprint of the most important fruit crop in the world and one of the most important food crops after staple cereals and cassava.

What animal has the longest DNA?

With 150 billion base pairs of DNA per cell (50 times larger than that of a human haploid genome), Paris japonica may possess the largest known genome of any living organism; the DNA from a single cell stretched out end-to-end would be longer than 300 feet (91 m).

Can a girl with Turner’s syndrome get pregnant?

Most women with Turner syndrome cannot get pregnant naturally. In one study, as many as 40% of women with Turner syndrome got pregnant using donated eggs.

What thing has the most chromosomes?

You might be surprised to learn that some species of ferns have over 1200 chromosomes. That’s over 26 times more chromosomes than humans’ measly 46! In fact, the world record holder for the most chromosomes is the fern Ophioglossum reticulatum with 1260 chromosomes!

What if a person has 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 mammal has the most chromosomes?

rodent Ichthyomys pittieriThe mitotic and meiotic chromosomes of the semi-aquatic 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 if a human has 45 chromosomes?

Turner syndrome, a condition that affects only females, results when one of the X chromosomes (sex chromosomes) is missing or partially missing. Turner syndrome can cause a variety of medical and developmental problems, including short height, failure of the ovaries to develop and heart defects.

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).

What is the C paradox?

The C value paradox is that the amount of DNA in a haploid genome (the 1C value) does not seem to correspond strongly to the complexity of an organism, and 1C values can be extremely variable. … The organism can regulate the C value, for example, by deleting stretches of sequence in heterochromatic regions.

What animal has 32 chromosomes?

What animal has the largest eye?

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

Do dogs have 23 chromosomes?

For example, humans usually have 23 pairs of chromosomes, for a total of 46. Chimpanzees, which are closely related to humans, have 24 while dogs, which are not as related, have 39 pairs.

What happens if a human has more than 46 chromosomes?

A gain or loss of chromosomes from the normal 46 is called aneuploidy. A common form of aneuploidy is trisomy, or the presence of an extra chromosome in cells. … People with Down syndrome typically have three copies of chromosome 21 in each cell, for a total of 47 chromosomes per cell.

What plant has the most DNA?

Paris japonicaThe largest genome ever found in a plant, weighing in at about 150 billion base pairs, was found in Paris japonica — a Japanese angiosperm.
