2. Applying: After completing your biology class, you feel like you better understand genetics. Then you see an article on social media about Adult-onset autosomal dominant leukodystrophy (ADLD). It links to a website that says that based on many years of research, scientists and doctors determined that ADLD is a genetic disease inherited in an autosomal dominant pattern, meaning if a parent has the disease, the child has a 50:50 chance of inheriting it. But the author of this website found a family where all six children have ADLD, even though only the mother has the disease, and there is no history of the disease in the father's family. This, the author says, shows that science is all wrong about ADLD because if there is really a 50:50 chance of inheriting the disease, then only 3 of the children would have it. Is this article correct or not? Explain your answer

IX. The blood of several members of a particular family was determined, and the results are tabulated below. Individual Blood Type Genotype Father Mother B Child 1 AB Child 2 B. Child 3 Grandfather (mother's side) Grandmother (father's side) AB Assuming that no adultery or adoption took place for all generations, answer the following questions: a. Give the most probable genotype for each individual. Supply your answers on the table above. b. What is/are the most probable genotype(s) for the grandmother on the mother's side? c. If the father and the mother decide to have two more children, what is the probability that the first would be female type A and the second male type AB?
Mrs. Xexy Lucero, GO, 25 years old asks Nurse Zasha about pre symptomatic genetic testing for Huntington's disease. Nurse Zasha should base her response on which of the following? (Select all that apply) a. One of the parents died of Huntington's disease b. if the woman is negative for the gene, her children should be tested to see whether or not they are carriers c. Presymptomatic testing cannot predict whether or not the gene will be expressed. d. If the woman is positive for the gene Huntington's, she will develop the disease later in life e. Both parents are carriers
reference text Ph.D Fernando, Harvard Professor of Genetic Epidemiology, knows a thing or two about Twins. He must know as he is head of the Twin Research Department where he works with about 3,500 pairs of identical twins, researching the influence of a person's genes on everything from the probability of being obese, whether or not they have religious beliefs, and, how, do they fall into sentimental issues. Anyone who is a twin, or who has ever met a pair of identical twins, can attest to how remarkably similar they are to each other, even in the rare cases of adopted twins raised in separate homes.A recent article begins with an introduction to two middle-aged twin sisters called Susan and Polly, one of the pairs of twins in the study group of the Department of Research of Harvard. Although they were treated almost as a single person growing up, with cuts from identical hair and clothes, the twins began to diverge in their teens as they they gained the freedom to make their own…
1. What role does a patient's genetics have in their symptoms of muscular dystrophy? What causes various mutations to cause distinct symptoms? (two to three sentences) (Think about why various mutations in different genes cause different illnesses.)2. What can family history teach you about a patient's muscular dystrophy inheritance and, hence, genetic basis? (two to three sentences)3. The X-chromosome contains the mutation that causes Duchenne Muscular Dystrophy (DMD). Explains how this impacts DMD inheritance and why DMD patients are disproportionately male. (two to three sentences)
12. A. B. C. D. 9:24 A. .5G prairiestate.desire2learn.com does that prove ne is the father of the baby or the person who committed the crime? Explain your answer. Hemophilia is an x-linked disease in which the blood does not clot normally; it is sometimes called "bleeder's disease." Hemophilia is caused by a recessive allele (h). The dominant allele (H) produces blood that clots normally. What is genotype of a man who is a hemophiliac? What is the genotype of a man with normal blood clotting? What is the genotype of a woman with normal clotting blood if her father was a hemophiliac? If a man with normal clotting blood and a heterozygous woman have children together, what would you expect for the genotypes and phenotypes of the children? 13. A dominant x-linked allele (B) gives normal color vision but the recessive allele (b) causes red-green color blindness. What is the genotype of a man with normal color vision whose father was color- blind?
2. Imagine that you are in your late 30s or early 40s and decide that you want a child. You realize that you’re at greater risk of having a child with Down’s Syndrome. What sorts of genetic screening are available today? If you find out that this child has this condition, do you think it’s appropriate to have an abortion? Why or why not? Question: Does elective abortion of fetuses with physical or other developmental disabilities have an effect on the perception of personhood, dignity, and rights in society? Explain.

A couple contemplating a pregnancy are in today for an appointment at a genetic counselling clinic to identify and interpret their risk of an inherited disorder. The nurse explains during teaching that all the following are characteristic features of fragile X chromosome of a 3-year-old male child EXCEPT: a. Macroorchidism b. Autistic behavior c. Intellectual disability d. Characteristic facial features e. Hyperextensible finger joints
A couple has had a child born with neurofibromatosis. They come to your genetic counseling office for help. After taking an extensive family history, you determine that there is no history of this disease on either side of the family. The couple wants to have another child and wants to be advised about the risks of that child having neurofibromatosis. What advice do you give them?
Mike was referred for genetic counseling because he was concerned about his extensive family history of colon cancer. That family history was highly suggestive of hereditary nonpolyposis colon cancer (HNPCC). This predisposition is inherited as an autosomal dominant trait, and those who carry the mutant allele have a 75% chance of developing colon cancer by age 65. Mike was counseled about the inheritance of this condition, the associated cancers, and the possibility of genetic testing (on an affected family member). Mikes aunt elected to be tested for one of the genes that may be altered in this condition and discovered that she did have an altered MSH2 gene. Other family members are in the process of being tested for this mutation. Once a family member is tested for the mutant allele, is it hard for other family members to remain unaware of their own fate, even if they did not want this information? How could family dynamics help or hurt this situation?

This is an example of incomplete penetrance. What could cause this?
