Question

The table shows the relative size of the genomes (total DNA in the nucleus), number of genes, and number of chromosomes for a variety of different organisms. What is the relationship between the complexity of an organism and the number of chromosomes that it has?

Answer 1

You don't show the table...but you should see that the more complex an organism, the more chromosomes and the more genes it has.

A bacteria has a small genome. perhaps it has about 5000 genes. it also has 1 chromosome.

Yeast are more complicated than bacteria. Saccharomyces cerevisiae (the yeast that makes beer, wine and bread, has about 6300 genes and 16 chromosomes.

A human has 46 chromosomes (23 pairs), and has likely around 20,000 genes.

Answer 2

Answer:

There is a weak link between advanced organisms and more chromosomes, but some organisms do not follow this rule.

Explanation:

Chromosomes are long strands of DNA associated with histone proteins in a complex arrangement that can be seen under an optical microscope on cells in the metaphase phase of cell division. These structures are located in the nucleus and vary from one species to another. In man, there are 46 chromosomes in each somatic cell.

Although we are bound to believe that more complex organisms have a greater number of chromosomes to manage all of this complexity, however, this is not always true. An example of this can be seen between plants and humans, although humans are more complex, the number of chromosomes is proportional to the number of chromosomes in plants.
