No, humans are not 20% bananas, although a commonly cited, slightly garbled, and often exaggerated statistic suggests a high genetic overlap due to shared basic cellular functions.
About 60 percent of our genes have a recognizable counterpart in the banana genome! "Of those 60 percent, the proteins encoded by them are roughly 40 percent identical when we compare the amino acid sequence of the human protein to its equivalent in the banana," Brody adds.
Back to the question on similarity between humans and bananas - overall, the vast majority of human DNA is very different to bananas. However, if you just look at the 2% of DNA corresponding to protein-coding genes, there is a pretty high degree of similarity between them; which is where the 50% comes from.
All told, there were about 7,000 “hits” – that is, banana genes that had a rough equivalent in the human genome – the equivalent of about 60 percent of the genes in one species having a recognizable “match” in the other.
These three species look alike in many ways, both in body and behavior. But for a clear understanding of how closely they are related, scientists compare their DNA, an essential molecule that's the instruction manual for building each species. Humans and chimps share a surprising 98.8 percent of their DNA.

Are humans 100% apes?
Molecular evidence suggests that between 8 and 4 million years ago, first the gorillas, and then the chimpanzees (genus Pan) split off from the line leading to the humans. Human DNA is approximately 98.4% identical to that of chimpanzees when comparing single nucleotide polymorphisms (see human evolutionary genetics).
Gene sequencing reveals that we have more in common with bananas, chickens, and fruit flies than you may expect. We've long known that we're closely related to chimpanzees and other primates, but did you know that humans also share more than half of our genetic material with chickens, fruit flies, and bananas?
Chimpanzees are our closest relative as a species and we share at least 98% of our genome with them. Our feline friends share 90% of homologous genes with us, with dogs it is 82%, 80% with cows, 69% with rats and 67% with mice [1].
The % DNA shared thing can be misleading, because it depends on how you look at it. The 96% carrot thing can be explained by the fact that the basic cellular processes that keep us going take up a good amount of gene space, and those things don't change much.
Yes, all humans share about 99.9% of their DNA, meaning only a tiny fraction (0.1%) of their roughly 3 billion base pairs differs, accounting for traits like hair/eye color, disease risks, and individual uniqueness, even though this small difference translates to millions of variations and structural changes (like extra or missing DNA) in the genome.
Surprisingly, we share 70% of our DNA with garden slugs. Yes, every living thing on our planet is related to some degree. Evolutionary biologists agree that all living species are descended from bacteria-like ancestors.
Humans and bananas share around 50 percent of the same DNA at a basic genetic level, a fact that often surprises people but is rooted in how genetics works. Scientists explain that this does not mean humans are half bananas.
Superfecundation is the fertilization of two or more ova from the same menstrual cycle by sperm from the same or different males, whether through separate acts of intercourse or during a single sexual encounter with multiple males. This can result in twin babies that have different biological fathers.
Yes, in a way, everyone on Earth is distantly related, and many geneticists suggest we are all at least 50th cousins due to pedigree collapse (ancestors appearing multiple times in family trees), meaning branches merge, making most people distant cousins, though the exact number varies and can be much higher. While we share common ancestors (Mitochondrial Eve/Y-chromosomal Adam), the "50th cousin" idea highlights how interconnected our family trees are, with most people having shared ancestors within the last few thousand years, making close relatives within the same communities quite common.
Yes, it's true. Humans and bananas have about 60 percent of their DNA in common because they share a common ancestor, which passed on the genes essential for basic biological functions such as growth and reproduction. These are common genes, which form part of key life processes that many living beings have.
While the genetic difference between individual humans today is minuscule – about 0.1%, on average – study of the same aspects of the chimpanzee genome indicates a difference of about 1.2%.
The bananas we eat are genetically modified organisms by their very triploid nature. Those genetic changes have natural origins, but given that bananas are sterile, the only way they can be meaningfully diversified is through our hands, using conventional or sophisticated technologies.
Can siblings share more than 50 percent of their DNA? Research has shown that full siblings can share as little as 37 percent or as much as 65 percent of their genetic variants. Do twins share the same DNA? Identical twins are the only siblings who share 100 percent of their DNA.
Another way to restate this is that your ethnicity divides with each past generation. You have 50% of the DNA from your parents. Then, 25% of that will be derived from your grandparents. Going further back, it's 12.5% from your great grandparents and continues onto your great-great-grandparents.
You share a family bond with your second cousins. You may share familial traits and genetic connections. Since second cousins share great-grandparents with you, their family records and stories may help you to gain a deeper understanding of your family history.
Chimpanzee the only animal thats has 94% DNA like Human Beings . The chimpanzee (Pan troglodytes), also known as the common chimpanzee, robust chimpanzee, or simply “chimp“, is a species of great ape native to the forests and savannahs of tropical Africa.
The most dominant view among scientists is the so-called "body-cooling" hypothesis, also known as the "savannah" hypothesis. This points to a rising need for early humans to thermoregulate their bodies as a driver for fur loss.
