Homologous chromosome

forty-seventh chromosome in their cells. Though this may seem like a minimal change beyond the norm, these are the instructions for how the body should develop and if anything is thrown off balance it could result in extreme anomalies. During a process called meiosis, a type of cell division, a sperm or egg may experience a critical error called nondisjunction where the sex chromosomes do not split correctly. When nondisjunction occurs, the sperm or egg will have an extra chromosome which will…

syndrome, also known as TS and gonadal dysgenesis, is a chromosomal deficiency affecting over two million women that occur when two of the X chromosomes in a female’s DNA are either incomplete or missing entirely. It usually becomes apparent when a female is only a few years old, or even shortly following her birth. The missing genetic material of the X chromosome keeps the female body from maturing on its own. Because Turner syndrome is different for every female and an individual experience,…

Cesar Lombroso said that all criminals shared some distinctive features like huge eye sockets, enormous jaws, and handle shaped ears. This theory forms part of an old debate of nature versus nurture that still continues in today’s days. Francis Galton’s field basis, “eugenics”, was that inheritance is more important than the environment and education. For him “talent, character, intellect, disposition, and other aspects of "natural ability," as well as physical features, such as height and eye…

without Turner syndrome, they have two sex chromosomes. For males, that would be one X chromosome and one Y chromosome. For females, they would have two X chromosomes. For females who have Turner syndrome, they have one normal X chromosome and the other is either missing or structurally altered. The chromosomal abnormality occurs as a random event during the formation of reproductive cells in the affected person’s parent. When a pair of chromosomes fails to separate during the formation of…

Lesson 2: Assignment 1-Genetic Information Resources, Assignment 2- Critical Thinking Exercise, and Assignment 3-Definition Matrix Tabytha Balash Ohio University  Assignment 1: Genetic Information Resources There are several areas to retrieve information on genetics. The following paragraphs will summarize three organizations that provide information on genetics, genetic counseling, and genetic testing. The summary will include what information is obtainable from the site, who supports the…

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 damaged, in that case they develop DMD just as a male would. An estimate of 29% males between the age of 5-9 are forced into a wheelchair from Duchenne muscular…

Have you ever heard of Wolf -Hirschhorn syndrome? Odds are you haven’t, considering that only around 1 out of 50,000 children have it. This rare condition may seem like it is unimportant and small, but people who have it may suffer from Delayed growth, Seizures, Intellectual disability, and Muscle weakness. Since there is no cure this drastically affects the person until the end of their life. During pregnancy while undergoing routine checkups in the first trimester a doctor can diagnose…

will adapt better with the second organism 4. Then the new gene called a transgene is delivered into the new recipient organism 5. The new gene is then passed on from one generation to the next. (University of Nebraska) Each person has 46 unique chromosomes…

females having an extra X chromosome in each cell. Most females with triple X syndrome are normal with sexual development and are able to have children. Triple X syndrome goes along with a higher risk of learning disabilities and delayed development of speech…

Does someone that you know have Triple x Syndrome or you want to know about it, well this research paper can tell you all about it. Triple x Syndrome can only affect women, and is created when an additional x chromosome is added to the other two x chromosomes. Triple x Syndrome was discovered by Patricia Jacobs in 1959 from one of her patients who was undergoing premature menopause. It can only affect women and they can be diagnosed with the disease at any age. The only noticeable effect it can…
