Biology October-22-08 Mendelian Genetics Cells in liver of chimera have cells of both of the two different sets of cells. Your liver does mitosis, and the different cells won’t pair during metaphase. There could be some cells from “Mary” and some cells from “Jane”. Meiosis typically results in four cells. These four “products of meiosis”, are not all genetically identical. The products do not always function of gametes. They always have half of the total chromosomes in the cell. Bacterial reproduction: - Binary fission is an asexual process; therefore populations are clonal and tend to be genetically homogeneous. Recombination requires getting DNA from different cells into close proximity. - The F factor transfer uses plasmids to copy the genes of one bacterium, then after the two bacteria bridge together, the plasmid gets transferred to a recipient cell. This uses rolling circle replication when the plasmid is being replicated. This process is called conjugation, and after the recipient cell receives the plasmid; the F factor can be distributed by the
