Genetic drift is essentially a process in which the frequency of alleles change randomly due to sampling error between generations. It can lead to major changes in a population over a short period of time and can also lead to a fixation of alleles in that population, increasing homozygosity. Heterozygote advantage is the potential advantage that could arise out of having a single allele of a gene, even if that gene is “bad”. With a heterozygote advantage, heterozygote carriers of a certain disease will be more likely to survive than with people without the disease allele. Since it helps survival, the gene spreads more throughout the population, which is why genetic diseases are occurring more often. Hemochromatosis is most common genetic variant in people of the Western European descent because of the bubonic plague. …show more content…
Macrophages is a type of white blood cell that hemochromatosis does not tend to distribute any iron to which causes the cells to lack iron, providing an advantage to those during the bubonic plague. This directly relates to heterozygote advantage--because Europeans survived carried this mutation, natural selection caused the gene to spread throughout the population, which is why it is common among them. Similarly, with cystic fibrosis, heterozygote advantage played an important role here as well, as carriers of this mutation helped protect people from tuberculosis. Tuberculosis caused of 20% of European deaths between the 1600’s-1900’s, which is why this gene spread among the European population over the years. With both these genetic mutations that provided some form of protection from the plague and tuberculosis, genetic drift also has a chance to increase frequency of alleles and homozygosity, which helps explain why more people would carry two alleles over the years, thus making the diseases apparent and ultimately
Test 3 Questions It was inevitable for Europe to not change after the Bubonic Plague, the disease killed many people which meant the people who were alive had to find a way to deal with the horrid aftermath of the Bubonic Plague. I think that some of the most important ramification of the Bubonic Plague is the blames some certain group of people got after the Plague and the different wars that took place. When the Bubonic Plague ended, many people took upon themselves to point figures at certain people like the Jews and the rich to tried to pinpoint the cause of the disease that had destroyed and damaged how society was functioning in Europe before the Plague. (Pages 310-311). One group in particular who was blamed the most were the Jews; they were blamed for causing the Plague because it was easier to blamed them since they were more of an outcast in the European in society in this period.
Bristol was believed to be the first city that the black death had reached in England, which helped create the spread of the disease because it was an important port and city during the medieval time. London was known as a crowded, busy city, with poor hygiene and living conditions, that were said to be dirty and disgusting. The River Thames carried more ships and infection to London which spread to the rest of England. The academic journal titled “The Bubonic Plague” written by Kristina Lenz, (obtained in the Nassau community college library) stated that “The disease could also have been brought into the country by Danish merchants
What I found to be interesting in the eleventh module on the lecture on Witch Persecutions and Trials – Part One was the Bubonic Plague. The Bubonic Plague was also referred to as the “Black Death” that occurred in the 14 century and killed 34 million Europeans, which was roughly one-third of the population. However, the Bubonic Plague did not only devastate Europe, but Asian and the Middle East as well for over 75 million people worldwide succumbed to the Black Death. Despite the fact that the Bubonic Plague originated in the 14th century it kept reoccurring every generation up to the 1700s. As the Bubonic Plague did not discriminate against its victims for both wealthy and the poor were struck with the illness. Moreover, the highest
The Bubonic plague was devastating to European society because many doctors as well as people
Europe went through a period of calamities during the fourteenth and fifteenth centuries. Populations were wiped out and the church lost much of its power. The population of Europe faced two main crises during the early Renaissance period: the black plague and the Great Schism, and through their reactions, the Renaissance was allowed to flourish.
The Bubonic Plague was a spreading disease. It infected and killed most of the population of Europe within a few years. The plague began spreading in 1348 when fleas caused this infection when they bit animals such as rats. The bacteria entered the skin through the flea bite which soon infected the lymph nodes. These rats stowed away on trade ships which quickly passed this deadly disease to humans. The Bubonic plague was very disastrous to the European society until it finally began to slow down in 1351. It killed so many people due to its rapid spreading. It lowered the religious belief and trust in God by many people in the community. Also, the local physicians lacked the knowledge of the plagues symptoms and its cure.
In the early 1330s, an outbreak of deadly bubonic plague occurred in Europe. The bubonic plague mainly affected rodents, but fleas were also able to transmit the disease to people. Once people were infected, they quickly infected others, which meant the disease spread very rapidly among the population. The plague caused fever and a painful swelling of the lymph glands called buboes. The disease also caused spots on the skin that started out red and eventually turned black, which is where “The Black Death” got its name. (The Black Death: Bubonic Plague) During the 14th century, there seemed to be no rational explanation for what was happening. No one knew exactly how the Black Death was transmitted from one patient to another and no one knew
The black death, also known as the bubonic plague, swept across Europe in the 14th century. During its time the plague claimed an estimated seventy five million lives. The plague though not longer existant, made a large impact as it was spread rapidly through the population. The plague first arrived in Europe in 1347.
In the 14th century the Black Death engulfed Europe killing an estimated 50 million people. The pandemic is considered extraordinary because it did so in a matter of months. This disease was carried by fleas, the Bubonic Plague is caused by a bacteria called Yersinia pestis, found mainly in rodents, in this case in rats, and the fleas that feed on them.
Bubonic Plague The majority of the assumptions revolving around the understanding of plague denote bacterial infection often said to bring calamity to a positively affected people. Individuals around the world especially those from the various faith that perceive it as Gods punishment to the people due to a wrongdoing and may take time before it ends. Plagues have been grouped historically With regards to the time and period of which an epidemic occurred or transpired (Galvani 25). A good example of a scourge that confirms the above allegations is the bubonic plague which is also referred to as the Black Death plague.
Did you know that sttasitcs demonstarte that 17% of all home burglars enter a home via the garage door ? In some cases they were able to enter another nduvals home thorugh their garage door, due to the fact that the owner forgot to lock it, however, in some insrances, they were avble to utlzie the garage door as a point of netry, due to a fault mechanism within the garagde door, that the owner failed to repair. With burgarly rates at an all time time hime, in Mission Bend TX, its highly reocmcned that you utilzie a garage door repair service, if you have noticed that theres a fault mechnasim witihn your garage door that iss preventing it from opening or closnng entirely.
Made of a canvas outer garment coated in wax, as well as waxed leather pants, gloves, boots and hat. A dark leather hood and mask with a very grotesque curved beak (Jackie Rosenhek, 2011). A serial killer, Halloween costume perhaps or a cosplay outfit for a horror movie? No, a doctor actually is what this outfit was meant for. Doctors wore this attire in the medieval times in order to protect themselves from the bubonic plague. We 've all heard of the bubonic plague in our history classes. We know the numbers and effects and how deadly it was. However the bubonic plague is still on the hunt and loose. Yes, numbers in outbreaks of the bubonic plague have doubled since 2014. There have been very few, but a pathogen such as the Black Death is not to be taken lightly.
Do you remember going or taking your child to the pediatrician office for booster shots? Do you remember getting a flu shot or chicken pox shot? Do you remember how sore your arm felt? How nervous, you felt? Scared, even? Were you one of the few who got sick after getting a shot? Did you expect to be immune to getting the flu after going for the shot, but still got the flu anyway? Were you one of the few who suffered severe complications because of the misinformation spread by the CDC , Center for Disease Control? What if you were told you didn't need some of those shots you were forced to take? Did you know it's against your rights to be forced to get a vaccine? Before we talk about vaccination, you should know how vaccines work.
Bubonic plague is an infectious disease that is spread by the bacteria Yersinia pestis. These bacteria remain in a dormant state primarily in a rat flea’s foregut. Once the flea has bitten a victim it regurgitates the contents in its foregut into the bite location. Once the bacterium has entered into a mammal’s warm body it begins to reproduce and spread throughout the mammal’s body. The reproduction of this bacterium creates large painful swollen lymph nodes which are called buboes. Once these buboes get large enough they begin to ooze infected body fluid so that any contact between an infected person and a healthy person will facilitate the spread of this disease.
