- Distinguish between genetic screening programs for newborns and adults, and discuss the scope and implications of genetic counseling.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 jointsDiscuss two ways to prevent getting an STI.?
- Please Answer with reason: When counseling parents about genetic transmission of an X-linked disorder, which concept does the nurse keep in mind? a. An X-linked disorder can be traced through the paternal lineage. b. A female can only pass an X-liked disorder to a son c. A male can pass an X-linked mutation to a son or a daughter d. A male with a mutation in an X-linked gene will manifest the disease. 5) The nurse explains to parents that if both of them are carriers of an autosomal recessive genetic mutation, the chance of each child NOT inheriting the disease (affected) is a. 25% c. 0% b. 75% d. 50%Answer with reason: When counseling parents about genetic transmission of an X-linked disorder, which concept does the nurse keep in mind? a.

- Answer the following questions on Genetic Counseling: 1. What “soft” skills does a genetic counselor need that might not be quantified by achieving a degree in a STEM field. Soft skills are interpersonal skills like active listening, time-management, and problem solving. 2. Why are pedigrees a tool used in genetic counseling and what might they tell the person or people being counseled? 3. Identify two to three tricky ethical situations a genetic counselor may run into when working with a couple who are expecting a baby.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?Mike was referred for genetic counseling because he was concerned about his extensive family history of colon cancer.

This is an example of incomplete penetrance. What could cause this?The genotype XXY corresponds to Klinefelter syndrome Turner syndrome Triplo-X Jacob syndrome8. Huntington’s disease is a degenerative disease of the nervous system that strikes in middle age. The allele that causes the disease (H) is dominant to the allele that results in the normal condition (h). Answer the following questions about the inheritance of this disease. A. What is the genotype of a man who is normal but whose father had Huntington’s disease? B. What is the genotype of a woman who has Huntington’s disease if both of her parents had Huntington’s disease? C. If a man who is heterozygous for Huntington’s disease marries a woman who is normal, what would you expect for the genotypes and phenotypes of their children? D. If a normal man marries a woman who is homozygous for Huntington’s disease, what do you expect for the genotypes and phenotypes of their children?
