Which of the following genetic diseases is/are inherited as an autosomal dominant trait: sickle cell anemia, hemophilia A, Huntington’s disease?
Recessive genetic disorders are more frequent than disorders inherited as dominant because :
a) recessive genetic disorders are limited to persons of the same ethnicity
c) dominant genetic disorders are never expressed in males
d) people carrying dominant genetic disorders always die before birth
e ) carriers are not eliminated by the disease before reproduction
What is the most common symptom in a genetic disorder and why?
Do all people exhibit this symptom of a genetic disorder?

PKU is manifest in early infancy and, if it remains untreated, generally leads to cognitive impairment. PKU is caused by a recessive allele with simple Mendelian inheritance. A couple intends to have children but consults a genetic counselor because the man has a sister with PKU and the woman has a brother with PKU. There are no other known cases in their families. They ask the genetic counselor to determine the probability that their first child will have PKU. What is this probability?arrow_forwardAnswer the following questions about the pedigree shown (below). Assume the trait is rare. • What is the most likely mode of inheritance for this pedigree? autosomal recessive What is the most likely genotype of the following individuals? • 1-2? homozygous recessive • Il-1? homozygous dominant • IV-2?

- Genetic Inheritance Patterms Retinitis pigmnentosa (RP) can be autosomal recessive, autosomal dominant, or x-linked. Apparently the dominant forms are often less severe. Eric's form of RP is Usher's Syndrome, which is an autosomal recessive inheritance (i.e., you must get a copy of the defective gene from your Mom and one from your Dad). Autosomal means it is not carried on one of the chromosomes that determines sex. Usher's Type II is recessive, so for Eric this means that both his Mom and Dad are carriers of this condition. His brother, Dirk, does not have any symptoms of RP. Question below - short answer approach Imagine you are a genetics counselor, and Dirk, Erik's brother, comes in to see you. Based on his parents, what are Dirk's possible genotypes for RP? What advice would you give Dirk about the chances of Dirk's children having retinitis pigmentosa if his wife is not a carrier? How would your advice change if his wife fully has the disease? Describe all the possibilities,…arrow_forwardAaBbCcDc AaBbCcD Ac Heading 1 Heading 2 Title Subtitle Subtle Em.. Emphasis Intense E...

Hemophilia is sex-linked and recessive (X h ). A man and his wife both of whom are polydactylous and have normal red blood cells have a child who is non-polydactylous and with hemophilia. What are their genotypes?arrow_forwardTrait: NeurofibromatosisThe dominant form is neurofibromatosis, caused by the production of an abnormal form of the protein neurofibromin. Affected individuals show spots of abnormal skin pigmentation and non-cancerous tumors that can interfere with the nervous system and cause blindness. Some tumors can convert to a cancerous form.The recessive form is a normal protein - in other words, no neurofibromatosis. Situation:Karina wants to know from whom she got her disorder. Her grandmother Ana has neurofibromatosis. Ana marries Angelo, who does not have the disease. They both have children named Christine (eldest), Monica, Joseph, Marco, and Yna (youngest). Monica, Marco, and Yna have the disorder out of the five children. Christine marries a man with the disorder, and they have two daughters, Kadita and Karina, who both have the disorder, and another daughter, Karrie, who does not have neurofibromatosis. Yna, on the other hand, marries a man with the disorder. They have four children,…arrow_forward
