A genetic counsellor is working with a couple who have just had a child who has a debilitating autosomal recessive form of a disease termed epidemolysis bullosa (which causes severe external and internal skin fragility resulting in blistering etc). Neither parent has epidemolysis bullosa, nor does anyone in their families. What should the counsellor say to this couple? OA. "Because no one in either of your families has epidemolysis bullosa, you are not likely to have another baby with epidemolysis bullosa. You can safely have another child." OB. "Because you have had one child with epidemolysis bullosa, you must each carry the allele. Any child you have has a 50% chance of having the disease." OC. "Because you have had one child with epidemolysis bullosa, you must each carry the allele. Any child you have has a 25% chance of having the disease." D. "Because you have had one child with epidemolysis bullosa, you must both carry the allele. However, since the chance of having an affected child is 25%, you may have more children without worrying about having another child with epidemolysis bullosa." OE. "You must both be tested to see who is a carrier of the epidemolysis bullosa allele."

There are six types of agglutinogen named C,D, E and c,d,e.the first three are dominant and last three are recessive.discuss
Pancreatic cancer is clearly inherited as an autosomal dominant trait in the family illustrated in Figure 23.1. Yet most cases of pancreatic cancer are sporadic, appearing as isolated cases in families with no obvious inheritance. How can a trait be strongly inherited in one family and not inherited in another?
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. Is colon cancer treatable? What are the common treatments, and how effective are they?

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?

Imagine you are working as a genetic counselor. A married couple makes an appointment to speak with you. Both have a genetic disorder, but they already have one child who does not have the disorder. They would like to have more children and were told by a friend that since their first child was normal their future children would be normal as well. Explain to them the probability of future offspring being normal or having the disease (assume that this is an autosomal disease). Be sure to tell them whether the disease is brought about by a dominant or recessive allele and what fraction of their children (if any) could be carriers for the disease.
Please help me with the following question: Von Willebrand disease is an inherited bleeding disorder. People with von Willebrand disease take a much longer period for blood to clot/stop than others. von Willebrand disease is either inherited in an autosomal dominant pattern or in an autosomal recessive pattern. Question: what is the genotype of the disorder? what are the phenotypic effects of the disorder? What is happening with the DNA to cause the phenotypic effects?
