Not necessarily. An onion has around 12 times as much DNA as we do, but they are certainly not more complex than we are. Although it is true, "onions have layers." But so do we. Scientists have been perplexed by this question for a while, but some Harvard research has suggested that not all DNA is functional -- some is "junk DNA." And some species dispose of their junk DNA, while others continue to replicate it. This could explain why seemingly simple species have a higher number of chromosomes -- they are simply hoarding their useless DNA.

∙ 8y agoMore complex eukaryotes do not necessarily have more chromosomes than simpler eukaryotes do. An example from the Holt Science book is that fruit flies have 8 chromosomes, potatoes have 48, and humans have 46. The human cells are more complex, but they don't have quite as many chromosomes as potatoes!

∙ 9y agoChromosomes contain the genes or the DNA of all organisms. Being more complex, does not mean that you have more chromosomes, for example: a human being has 48 chromosomes while chickens and dogs both have 78.

∙ 8y agoNot at all. We have 46 pairs and the plant called the Adders-tongue has 1260 pairs Here is a list: https://en.wikipedia.org/wiki/List_of_organisms_by_chromosome_count

∙ 12y agoNo, for the reason that a fern contains more chromosomes than a human, but a human is much more complex.

∙ 13y agonot necessarily, size does not matter. apparently a kind of shrimp has over 200

∙ 13y agoNo, larger organisms do not necessarily have more chromosomes.

Is an organism with a chromosome number of 300 is more complex than an organism with a chromosome number of 2?
No, just because a the number of chromosomes are higher, does not make it complex. There are certain plants with over 1,000 chromosomes, while we only have 46 and we are deffinetly more complex than a plant.
The condition in which a diploid cell has an extra chromosome is called?
Polyploidy is the condition in which a normally diploid cell or organism acquires one or more additional sets of chromosomes. In other words, the polyploid cell or organism has three or more times the haploid chromosome number. Polyploidy arises as the result of total nondisjunction of chromosomes during mitosis or meiosis.
Does the number of chromosomes correspond to the size of an organism?
No. Chromsomes are subject to breakage and fusion over evolutionary time, which can result in an increase or decrease in chromosome number, and the forces behind that are independent of an organism's size.
What is polyploidy?
Polyploidy is the condition in which an organism has extra sets of chromosomes. It can be defined as a chromosomal alteration in which the organism posses more than two complete chromosome sets. Classified as an accident in cell division.
How many cells does a multi-cellular organism have?
There isn't a strict limit. At some point an organism may become simply too large to maintain itself but the exact number of cells such an organism might have is incalculable.

Can organisms with fewer chromosomes reproduce more easily than organism with more number of chromosomes?
can organisms with fewer no of chromosome reproduce more easily than organim with more

Why is the eukaryotic cell's DNA sometimes in chromosome form?
The DNA of the Eukaryotic cell is sometimes seen in chromosome form because of the simplicity of the cell. The more complex the organism, the less likely the DNA will be seen in chromosome form.

What is considered aneuploid?
aneuploidy usually reslts from non-disjunction (failure to separate) of homologous chromosomes during meiosis (the creation of gametes). It results in an organism having the wrong number of a certain chromosome. The two most common forms are monosomy (only one chromosme eg. Turner syndrome) and trisomy (three of a chromosome eg Down and Klinefelter syndrome) from non-disjunction, the two chromosomes line up at the equater of a cell as an X, ready to separate, but it doesn't, this reults in one egg/sperm having 0 of a chromosome and another will have 2. If the one with 0 then forms a zygote with a normal egg/sperm the zygote could have only 1 chromosome -from the normal egg/sperm. If the one with 2 forms a zygote the zygote will have 3 of the chromosome, 2 from the mutated gamtete and 1 from the normal gamete.
Why does the X chromosome affect an organisms phenotype more than the Y chromosome?
The X chromosome contains considerably more genetic material than the Y chromosome.
What is a polyploid animal?
Diploid: adj. 1 Double or twofold. 2 Having a homologous pair of chromosomes for each characteristic except sex, the total number of chromosomes being twice that of a gamete.-n 1. a diploid cell. 2. An individual characterized by a diploid chromosome number.It has two copies of each chromosome.
How many bases does a single human chromosome contain?
Every chromosome is a different size so the number of base pairs is different for each chromosome. X chromosome has more that 153 million base pairs (greater that 306 million bases) Y chromosome has around 50 million base pairs (around 100 million bases)
