Science: Ask a Geneticist

According to the facts of these geneticists, I have learned a lot. One of the most interesting genetics facts that I have learned about is that why humans have more or fewer genes than chimps. The answer to that is that both started off with the same mumber of chromosomes 5 million years ago. But then the two started to drift apart in evolution causing their genomes to change. Some sections of that were lost, gained and copied. The chromosome also fused together or broke apart so that 2 human chromosomes were similiar to 2 smaller ones of a chimp. The genome that code for genes only differ by 1.2% saying that they are 98.8% the same. Another cause to the difference is the amount of protien that reaches the brain. All these reasons help better understant this topic.
