Best answer: Do chromosomes indicate complexity?

Does chromosome number correlate with complexity?

The number of chromosomes does not correlate with the apparent complexity of an animal or a plant: in humans, for example, the diploid number is 2n = 46 (that is, 23 pairs), compared with 2n = 78, or 39 pairs, in the dog and 2n = 36 (18) in the common earthworm. There is an equally great range of numbers among plants.

Do chromosomes mean more complex?

More DNA does not mean more complexity. You have just over three billion base pairs of DNA (base pairs are just one way to measure the amount of DNA). … This much simpler organism has 100 times the DNA that you do.

Is chromosome number a good indicator of an organism’s complexity explain?

The answer is no. The chromosome number is not correlated to the complexity of an organism. … It is because larger chromosomes contain more genes than the number of genes found in the smaller ones. If there are more genes that contain coding or instructions for a particular trait, then an organism is more complex.

Is the gene number related to the complexity of an organism?

Even so, genome size and the number of genes present in an organism reveal little about that organism’s complexity (Figure 1). Figure 1: Chromatin has highly complex structure with several levels of organization. The simplest level is the double-helical structure of DNA.

Does more genes mean more complex?

Accordingly, one might expect that: «more complex organisms have larger genomes and contain a larger number of genes». That is, throughout evolution an increase in genome sizes and the number of genes is expected.

What has the most complex DNA?

According to the Johns Hopkins scientists, bread wheat has one of the most complex genomes known to science, containing an estimated 16 billion base pairs of DNA and six copies of seven chromosomes.

What does the number of chromosomes say about the complexity of an organism?

Does the number of chromosomes determine the complexity of the organism? Answer 1: No, the number of chromosomes is actually barely related to complexity at all. For instance, humans have 46 chromosomes (2 sets of 23) whereas small deer have 6 chromosomes, and carp have over 100.

Is the number of chromosomes in each cell of an organism a good indicator?

Yes, the number of chromosomes is a good indicator of an organism’s complexity, but the amount of DNA matters even more.

Does the number of chromosomes reflect the intelligence of an organism?

Scientists count individual strands of chromosomes. They count individuals not every organism has pairs. … The number of chromosomes is NOT related to the intelligence or complexity of the creature. There is a crayfish with 200 chromosomes.
