Classical genetics

To whom it may concern: This letter is to inform you about the genetic status of Aminata and Nelson and to help you advise them on their decision of whether or not to have a child. The probability that Nelson and Aminata’s child will have sickle cell anemia is a 1 in 20 chance. By calculating the probability that Nelson is a heterozygous carrier of the HbS gene (.67), then the probability that Aminata is also a heterozygous carrier of the HbS gene (0.30), and finally the probability that two…

Common choice is the differential survival and propagation of people because of contrasts in phenotype. It is a key instrument of development, the change in heritable qualities of a populace after some time. Charles Darwin promoted the expression "regular determination", and contrasted it and manufactured choice. Variety exists inside all populaces of living beings. This happens mostly on the grounds that arbitrary transformations emerge in the genome of an individual living being, and…

“GATTACA” is a movie that is set in the “not-so-distant” future where genetic engineering and DNA are used for discrimination and determining one’s fate just minutes after they are born with just a prick to their heel and a blood sample. When Vincent Freemen was born naturally (without the use of genetic engineering and DNA modification) his sample showed that he had a 99% chance of acquiring a congenital heart defect. His life expectancy was estimated at 30 years of age. With Vincent’s…

Its something seen straight out of a futuristic movie, genetic human engineering but the future is here and the controversy is real. After studying this topic I do not believe that designer babies are ethical and should be used. The talk of ‘designer babies’ started in the early 2000s and hasn't left scientists mouths since. The only question now is, will it create a utopian society or a dystopian one? To go into further depth about the topic, designer babies is the selecting and or deleting of…

The study of heritable changes in gene expression without a change in DNA sequence is defined as epigenetics. Epigenetics covers a variety of areas in life science such as, biological sciences, effect of pollutants, etc.. The study of epigenetics is important because it allows researchers to trace the causes of certain diseases, follow the effects pollution has in humans and understand how eating habits can alter a person's appearance. Epigenetic modifications can affect the level of expression…

Cystic Fibrosis was first discovered in 1938 by Dr. Dorothy Hansine Andersen, she described the characteristics of the disease of the pancreas, lungs, and other organs, but this was not much information to go on from. She later discovered more information on Cystic Fibrosis in 1949, she found out it was caused by a recessive mutant gene. Cystic Fibrosis(CF) is a thick and sticky mucus that clogs the airways, making it hard to breathe and causing damage. It is caused by a defect in a gene that…

course of her 50-minute talk. As her introduction, she appropriately began by providing a synopsis of her research by describing the mission of her lab and providing an overview of her interest in the interaction between DNA viruses and the eukaryotic genetic regulatory systems. To emphasize the broad goals of her lab, she introduced examples of model viruses, such as the gamma herpes viruses and MHV68, and spoke to some of the more specific strategies her lab uses to study them. After…

Zika Could Potentially Stop Cancer from Recurring Zika infects and kills the stem cells that turns into cancer Annika Castaneda | Science | 9/8/2017 Studies say that in human cells, the Zika virus infected and killed the stem cells that become a glioblastoma, or an aggressive brain tumor, but it left healthy brain cells alone. Will this create a new cure or treatment, or will it also spread through your whole body too? Jeremy Rich, and a team of scientists think they can help cure glioblastoma,…

Gattaca Summary and Genetic Things Summary Vincent Anton Freeman was born with a 99% chance of getting a heart disease and dying at the age of 30. Vincent dreamt of space but, companies didn’t want to hire people like him so they don’t waste resources on someone who will die that soon. To get a job at the space organization, Gattaca, Vincent buys the genes of genetically engineered, Jerome Morrow. At Gattaca Vincent gets scheduled to go on a mission to Titan, the largest moon of Saturn.…

Ethics Behind Designer Babies Designer babies can be described as a baby whose genetic makeup has been artificially selected by genetic engineering combined with in vitro fertilization to ensure presence or absence of particular genes or characteristics. There are many pros and cons to creating an embryo or “designing” one. However, this leads to ethical problems. While creating a designer baby gives the parents desired traits, it is not completely safe, because it causes many problems such…
