Science: Ask a geneticist

When I read the websites that were given, I learned many different facts about genetics and genes. In one of the articles, they talked about humans and chimps. What I learned was that, even though chimps and humans have a different number of chromosomes, we might have close amounts of genes. Geneticists think that the difference between the two, (humans and chimps) is that the genome don't code for genes. Also, even though goldfishes are simpler then humans, they have 96 chromosomes, which amazes me. What I also learned is that a chromosome is a package containing a chunk of genomes. Like some of the simplest forms of life, like bacteria, can keep all their DNA in a single chromosome, unlike more complex organisms, like humans, that divide their DNA's into chromosomes, which I thought was pretty amazing.
