If you could type 60 words per minute, eight hours a day, it would take approximately 50 years to type the human genome. This has led to claims that, for instance, we share half our DNA with bananas and 60% with fruit flies. Humans share 60% of genes with fruit flies, and 2/3 of those genes are known to be involved in cancer. The following table summarizes both the average percent DNA shared for different types of relationships, and the expected range of percent DNA shared. Why do fruit flies serve as good models for humans? The humble Drosophila melanogaster. Can you draw a cladogram that depicts the evolutionary relationship among humans, chimpanzees, fruit flies, and mosses? Just how alike are fruit flies and people? 4th victim dies after gunman's attacks in Illinois.

(Hint: Recall how a gene is expressed to produce a protein. This process might explain the genetic differences among species like humans, onions, and fruit flies. Humans have large amounts of junk DNA: about 97 per cent of the 3 billion DNA pairs in the genome are thought to be "junk", and so inter-changeable. Over 99%? For example, fruit flies share 61% of disease-causing genes with humans, which was important when NASA studied the bugs to learn more about what space travel might do to your genes. the primary sequence of the corresponding protein is identical. It's the self-replicating material that passes on hereditary traits from one generation to the next. Humans share DNA with every other living organism on earth. In the case of comparisons with simpler animals like fruit flies, though, these comparisons are highly misleading.   You share 98.7% of your DNA in common with chimpanzees and bonobos. A comparison o… percentage similarity of this gene and the protein it expresses in humans versus other species. "The remarkable thing is that despite being very far apart in evolutionary time, we can still find a common signature in the genome of a common ancestor," Brody says. Asked by Wiki User. They can be good substitutes for people. Genes which determine animal complexity – or what makes humans so much more complex than a fruit fly or a sea urchin – have been identified for the first time. How much DNA do plants share with humans? Although fruit flies have a genome that is 25 times smaller than the human genome, many of the flies' genes correspond to those in humans and control the same biological functions. Bad news: I'm 75.
