Document Summary
Most research work is done on the haploid phase of chlamydomonas. Because once a mutation is done, we can see its direct effect, and don"t have to worry about dominance to other genes. If there is only one mating type (positive or negative, male or female in our case), then they reproduce solely with mitosis, it is purely asexual reproduction. Multi-cellular life evolved multiple times, it is not monophyletic. If we look in the genomes of different algae and see what genetic changes are needed for the evolution of multi-cellularity. Multi-cellularity is complex to explain because the cell has to give up the right to reproduce. Those other cells also have to agree to die. If you compare chlamy to another algae they are very similar. However the other algae is multicellular, and chlamy is not. Evolution of the eye is one of hardest things for evolutionary biologists to explain.
