Use the following data to construct a cladogram for the major plant groups. When it comes to insects' DNA, humans have a bit less in common. Humans and fruit flies share 60% percent of the same DNA, which means that they are 60% human. For example, a March 2000 study comparing the fruit fly genome with the human genome discovered that about 60 percent of genes are conserved between fly and human. Humans share at least some genes (DNA) with all living organisms. (Hint: Recall how a gene is expressed to produce a protein. How many grams in a cup of butternut squash? Researchers have found that two-thirds of human cancer genes have counterparts in the fruit fly. Table 2: Percentage Similarity of the GAPDH Gene and Protein with, Why is the percentage similarity in the gene always lower than the percentage similarity in the protein for, each of the species? This process might explain the genetic differences among species like humans, onions, and fruit flies. They share about 98.7 percent of their DNA sequence with chimpanzees and bonobos, which are the animals most closely related. Crickets, as it turns out, possess 11 times more genetic material than fruit flies. “Organisms like fruit flies may be careless about copying junk DNA when replicating their chromosomes, giving them compact, junk-free genomes,” Petrov points out. It's actually a vicious cycle. You should make some preliminary observations about. ALL animals and plants share the same DNA which is basically a code of only 4 'letters' which code for the same amino acids from which all proteins are made. Use the pictures of each species to answer the following, 3a) Fill out the following character matrix with a “O” for the ancestral trait (outgroup), and a “+” for a derived. Can you draw a cladogram that depicts the evolutionary relationship among humans, chimpanzees, fruit flies, and mosses?

A handful of examples tell the tale. If your impeached can you run for president again? What percentage of genes do humans share with bananas? Humans share DNA with every other living organism on earth. The information is encoded in the sequencing of four chemical bases: adenine (A), guanine (G), cytosine (C), and thymine (T). This has led to claims that, for instance, we share half our DNA with bananas and 60% with fruit flies.

Picking two insects eliminates complexities that can arise during evolution of very different species, such as humans and crickets. Even though the fruit fly has only about 13,000 genes, compared to the 70,000 to 100,000 genes found in humans -- we're more similar to fruit flies than not. This has led to claims that, for instance, we share half our DNA with bananas and 60% with fruit flies. Why do fruit flies serve as good models for humans? How much DNA do plants share with humans?
