Article Response
In the article “Molecular Evolution of Genetic Sex-Determination Switch in Honeybees”, it is explained how scientists have finally found the molecular switch for sex differences in the honeybee after 200 years. The article discusses the start of this study which was first conducted by a monk by the name of Johann Dzierson who was trying to figure out how males and females were formed in bee colonies. Using new technology and modern mechanisms that our ancestors did not have scientists “studied 14 natural sequence variants of the complementary sex determining switch (csd gene), for 76 genotypes of honey bees.” Scientists found that bees were ideal for their research because they only have one gene locus responsible for sex determination. Eventually through multiple testing, scientists were able to take an allele out of the genetic material and show how the male is formed from a diploid genotype. Scientists were then able to narrow down the regions responsible for a bee that is not female in the gene and discovered that there were at least 5 amino acids which could lead to different conformational states. Also through this study, scientists were able to determine the 3 amino acids that give bees their lethality. My view on this is that scientists should continue to explore and breakdown everything that is needed to know for the existent species that we have on Earth. This way we can learn the properties of many of the organisms that live here and this could even lead to a discovery that is essential to our survival. In this case, the study was not necessarily for that purpose, however learning how different organisms work can be essential to ensure the organisms survival. To improve the rate at which we can discover these things about each organism, it is very important that new and more modern technology is created so that the time it takes to do such things is a lot less. New and more modern technology equals new and more discoveries that can be essential to the survival of humans and the organisms on Earth.

Unit Artefact
![Picture](/uploads/1/6/5/6/16564394/8426289.jpg)
For the genetics unit, the artefact that I chose to represent is karyotyping. This artefact was selected when we were doing the genetics summative. Basically, in the lab report we were comparing many factors and we were also using the karyotypes to determine the murderer of the captain. The karyotypes were used to determine which person on the ship possessed certain diseases. This item is significant to me because it showed me that by using the karyotypes of different people, you can use it to determine which genetic diseases they have. I also learned by doing this activity that if there is one missing chromosome in any pair, that it could result in a genetic mutation which could be the cause of a disease that the person would have to live with until they pass. If I chose an occupation in the medical field in which I would have to be analyzing the causes of one’s disease then this is the perfect introduction to it. This is because as a geneticist I would be able to examine the karyotypes of different people and be able to tell what genetic disorders they may have, so that it can be treated right away. Also further research in this may even produce ways to perhaps synthetically reproduce certain chromosomes and if someone is missing a chromosome or has one that has been damaged, it can be replaced. Even though that will take a long time to invent and make it usable it is entirely possible with new technology. This specific artefact makes me wonder a lot about what we could with chromosomes and that is why it is significant to me. This has helped me to better understand the unit because it shows me how karyotyping can be used to locate and determine genetic diseases.
