    their spine is curvature surgery may be needed (Mayo Clinic, 2014). Epidemiology: Duchenne muscular dystrophy approximately affects 1 of every 5,600 to 7,700 males between the ages of 5 - 24. Females are very rarely affected by DMD, and will not have the dramatic signs like the males do. Although if they are carriers of the mutated chromosome, they possibly will experience small symptoms of weakness in their muscles. However there were cases reported where a female’s second chromosome is…

    Duchenne Muscular Dystrophy In this world, there are many diseases that are being caused by the X chromosomes or the Y chromosomes. Some of the diseases could be passed down from generation onto the next because it is gene and some of the diseases can be treated and which later on causes for it to make it worse. The diseases that would always be there would be Down Syndrome, Huntington’s Disease, Hemophobia, and many more. As you can see, this paper is going to be able a genetic disease that is…

    SIMULATION CROSS BETWEEN A HETEROZYGOUS FEMALE AND A HEMOPHILIA MALE BACKGROUND INFORMATION The survival of the human species throughout the last millions of years has been solely based on the randomized process of genetic inheritance from one generation to the next generation. Instead of duplicating their genetic information and create identical offspring, humans produce sex cells, through the process of meiosis, that carry only half of the genetic information, and fertilize them in order to…

    Quentin’s physician believes had has Klinefelter syndrome due to his enlarge breast tissue, long limbs, and abnormally small testes. Based on my findings, “Klinefleter syndrome is a chromosomal condition that affects male physical and cognitive development”(Genetics Home, 2015). This genetic disorder is a result of having 2 X and a Y-chromosomes mixed together. Individuals living with Klinefeter syndrome typically have small testes that do not produce as much testosterone as usual”(Genetic Home,…

    Pigmentosa for 20 years, Eric A. Pierce, a ophthalmologist, found out that what part of the chromosome goes wrong will cause the RP happened. In the experiment, he first looks for the mice that have the RP, and take out their genes to compare to the candidate genes from human. Then, they matched them and used the conventional molecular genetic technique to find out that the RP1 gene on…

    Chromosomes, or strings of genes carrying genetic information, are vital to the existence of living things. A specimen cannot have more or less than how many that particular species needs. In humans, this number is 23. The 23rd pair of chromosomes, referred to as Group X, contain the sex cells that decide the gender of the organism. If a Y chromosome is present, the organism is male, and if not, it is a female. If the chromosomes fail to separate correctly during meiosis (type of cell division…

    Sperm containing the Y chromosome with a properly functioning SRY gene determines male gender, and if contains the genetic material of the X chromosome is shaped female. The presence of the SRY gene is the basic criterion of gender gene in humans. Discovered in 1990 by a group of P. Goodfellow from the University of Cambridge ,SRY gene is called the "central switch of the masculinity" and is located on the short arm of the Y chromosome locus…
