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. According to this hypothesis, the organism requires a certain amount of DNA, which could consist of any sequence.
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….Number of genes and complexity of the organism.

What animal has the most complex DNA?
water flea Daphnia
What is DNA complexity?
Complexity (denoted by N) is the number of base pairs of unique or nonrepeating DNA in a given segment of DNA, or component of the genome. This is different from the length (L) of the sequence if some of the DNA is repeated, as illustrated in this example. 500 bp is sequence a, present in a single copy.
How many genes are in a virus DNA?
The smallest viruses have only a few genes; the largest viruses have as many as 200. Genetically, however, viruses have many features in common with cells.
Are viruses in your DNA?
Eight percent of our DNA consists of remnants of ancient viruses, and another 40 percent is made up of repetitive strings of genetic letters that is also thought to have a viral origin.”
Are we born with viruses?
Many latent and asymptomatic viruses are present in the human body all the time. Viruses infect all life forms; therefore the bacterial, plant, and animal cells and material in our gut also carry viruses.
Do bananas share DNA with humans?
“You share 50 percent of your DNA with each of your parents. But with bananas, we share about 50 percent of our genes, which turns out to be only about 1 percent of our DNA,” emails Mike Francis, a Ph.
Which race has the most genetic diseases?
Examples of genetic conditions that are more common in particular ethnic groups are sickle cell disease, which is more common in people of African, African American, or Mediterranean heritage; and Tay-Sachs disease, which is more likely to occur among people of Ashkenazi (eastern and central European) Jewish or French …
Can two strangers have the same DNA?
Your DNA is arranged into chromosomes, which are grouped into 23 pairs. Theoretically, same-sex siblings could be created with the same selection of chromosomes, but the odds of this happening would be one in 246 or about 70 trillion. In fact, it’s even less likely than that.
Is man still evolving?
In recent years, scientists have accumulated intriguing evidence that humans continue to evolve despite cultural and behavioural buffers against environmental stress. However, predicting the future course of human evolution is futile because we cannot accurately predict the environmental stresses that we will face.
