1.They are anything but difficult to raise, have numerous posterity per mating, can prepare themselves, and have assortments in genotype and phenotype that are effectively detectable. 2.1st law- Attributes of a living being are controlled by sets of alleles that different in equivalent numbers into various gametes therefore of meiosis. 2nd law- At least two sets of alleles isolate freely of each different subsequently of meiosis, gave the qualities concerned are not connected by being on a similar chromosome. 3. This was fortunate because crossing over was able to occur. Being on different chromosomes, he was able to study frequencies. If they would have been on the same chromosome it would have been much harder to determine much of what…show more content…
When further looking into the experiment he noticed that the capsulated smooth strain transformed into the capsulated rough strain due to the heat killed smooth being broken and releasing the capsulated smooth strain fragment. -Avery experiment- he stated that the transforming agent was DNA but instead of doing this lab in with a mouse he did it in test tubes. He extracted the active principle from smooth cells. He then took 5 test tubes each with a pretreatment (one with Trypsin, one with RNase, one with DNase) and two with no pretreatment. He then serially diluted DNA; adding medium and pretreatment to determine which part of the extract is active. He then added rough pneumococci and incubate to each test tube. He then added the S-cell extract to all test tubes but one of the non-pretreated test tubes. He found that no pretreatment and no s cell extract resulted in rough growth, no pretreatment and added s cell extract resulted in smooth growth, trypsin pretreatment and added s cell extract resulted in smooth growth, RNase pretreatment and added s cell extract resulted in smooth growth, and finally DNase pretreatment and added s cell extract resulted in rough growth. -Hershey-Chase experiment- first mixed radioactively labeled phages with bacteria which the phages then infected the bacterial cells. Second, agitate in a blender to separate phages outside from the bacterial cells. Third, centrifuge
