What organism has the highest number of chromosomes?

Question

I need to find out what organism (plant or animal) contains the highest number of chromosomes.

Answer 1

dear

there is many polyploid plants which have very big polyploid number

but if u need an organism with the highest monoploid number

as i know it is a kind of Bracken which have 1262 chromosomes in its diploid nucleus

bye

Answer 2

>>>>>Does a higher number of chromosomes lead to more variation and therefore faster evolution? The rate of evolution depends on the time between generations. A mouse with 3 Gb haploid genome on 21 chromosomes will evolve faster than an elephant with a similar amount to total DNA but on 57 chromosomes (haploid number including sex chromosome). The number of chromosomes will increase the diversity of gametes due to independent assortment. This is the number of ways that you can package chromosomes. Crossing over is not random. There are hot spots that are more likely to be places for crossing over. The longer the chromosome is, the more opportunities for crossing over. So, a large chromosome may in effect act as several smaller chromosomes due to multiple crossing over junctions. Look at the definition of evolution: Change in allele frequency between generations. A bacterium with one chromosome will evolve faster because it's generation time is 10 minutes.

Answer 3

The answer changes every few months as new polyploid plant strains are discovered.



Last I heard the record belonged to a fern of the genus Nephrolepus, but the website below suggests that a fern of the Ophioglossum genus is the current record holder. I have no idea whther my information or that website is more up to date.
