Document Summary
5: sex determination systems, chromosomal xx, xy, xx, xo, zz, zy. Xxy male are herero: temperature determinant, environment, genic and genetic, not on chromosome through out genome, drosophilia: ratio of x to haplio of autosomes, humans: presence of the y, very much seen in turners syndrome. This is overcome by dosage compensation: mosaic. Simultaneous fertilization of egg with two sperm: autopolyploidy:all chromosome sets are from same species, allopolyploidy: chrom. 7: linked genes, morgan and sturtevant, those that are close together on the same chromosome. 8: advantages of bacteria/viruses, reproduction is fast, many progeny produced, haploid genome allows mutation to be exposed directly, asexual reproduction simplifies, growth in lab is easy, genomes are small, techniques are available, medical importance ix. Can be genetically engineered: prototroph vs. auxotroph, pro: wild type bacteria that can synthesize all cmpds needed for growth from simple ingredients, auxo: mutant strain that lacks one or more enzymes required for metabolizing nutrients.
