Jonah and Jana are siblings. Jonah has the genetic disorder cystic fibrosis, caused by inheriting two mutant alleles of the CFTR gene (the gene that when mutant causes cystic fibrosis) - one allele was inherited from each parent. Jana does not have cystic fibrosis. Which of the following statements is/are true? Jana does not have the CFTR gene. Jana has two copies of the CFTR gene. Jana has at least one copy of the non-mutant allele of the CFTR gene. Jana has two copies of the mutant allele of the CFTR gene.

Hereditary hemochromatosis is an autosomal recessive genetic disorder that causes the body to absorb too much iron from the diet. This excess iron is stored in the body's tissues and organs, particularly the skin, heart, liver, pancreas, and joints. Because humans cannot increase the excretion of iron, excess iron can overload and eventually damage tissues and organs. A young couple, Bart and Jenny, are expecting a child and are aware there might be a chance that their child could be affected by this disorder. Jenny (the wife) has ichthyosis, but Bart (her husband) is unaffected and completely normal with respect to the allele responsible for this disorder. Both Bart and Jenny were Biology majors as undergraduates. Knowing a little about the pattern of X-linked recessive inheritance, Bart and Jenny were concerned when ultrasound revealed that they would be having a son. However, genetic testing performed on the baby shortly after birth revealed that their newborn son, Mark, did not…
Hereditary hemochromatosis is an autosomal recessive genetic disorder that causes the body to absorb too much iron from the diet. This excess iron is stored in the body's tissues and organs, particularly the skin, heart, liver, pancreas, and joints. Because humans cannot increase the excretion of iron, excess iron can overload and eventually damage tissues and organs. A. Symptoms of hereditary hemochromatosis include fatigue, joint pain, arthritis, diabetes, heart disease, skin discoloration, delayed puberty in males, and premature menopause in women. All of these symptoms result a single mutation in a specific gene. Name and define this genetic phenomenon and explain how it relates to this specific genetic situation described above.
Jan and Michael are both carriers for the cystic fibrosis allele. If Jan and Michael have five children, what the probability that three or more of the children will have the disease?

A man who had hemophilia (an X-linked recessive genetic disorder), married a woman who had no family history of hemophilia whatsoever. The couple had consulted a genetic counselor when they first contemplated having children due to concerns that their future children might have hemophilia. Genetic testing of both future parents revealed that the husband did, in fact, possess the Hemophilia A allele but his wife was completely normal with respect to hemophilia. Much to their shock, their first child, a daughter, had a mild blood clotting disorder. Karyotyping was performed to determine whether this daughter had an…
Cystic fibrosis is a genetic disease that causes an abnormal production of mucus which in turn can cause damage and infection to the lungs and other organs. In the following pedigree, black indicates all those persons afflicted with cystic fibrosis (square symbols are males, circles are females). There's a healthy couple and they have two children. One is a 23-year-old daughter with cystic fibrosis who is married to a 24-year-old male who is healthy. The other child is a 15-year-old son who is healthy After studying the pedigree, write a logical hypothesis suggesting the cause of cystic fibrosis in terms of dominant or recessive alleles. On the basis of your hypothesis, write an appropriate genotype for both of the parents. Using a Punnett square, what is the probability of the parents having a child with cystic fibrosis? If the daughter's husband is a carrier of cystic fibrosis, what is the probability that they have a child with cystic fibrosis? Show your Punnett square.
Because Elsa has received a confirmed diagnosis of beta-thalassemia major, which of the following statements is true about her parents? Only her mother carried the gene that caused her blood disorder. Only her father carried the gene that caused her blood disorder. If her parents have another child naturally, there is a 100% chance that the second child will be diagnosed with beta-thalassemia major. If her parents have another child naturally, there is a 25% chance that the second child will be diagnosed with beta-thalassemia major.
One of your patients, a six-year-old girl who suffers from Sickle cell anemia, an inherited blood disorder in which red blood cells are abnormally shaped and fragile, leading to a short supply of red blood cells. These abnormal cells can also get stuck in small vessels, which prevent blood flow, leading to fatigue, pain and other severe complications. Sickle cell anemia is an autosomal recessive disorder. Neither of your patient's parents has sickle cell anemia. What is the most likely genotype of her parents? (The normal beta-globin allele is abbreviated as B, and the abnormal allele as b.) one is B and one is b one is BB and one is bb both are Bb both are bb both are BB
If diseases such as cardiovascular disease (hypertension and atherosclerosis) are familial, is this an indication that there is a genetic contribution to these traits? What would you do to confirm that genetics is involved in this condition?
Albinism is a recessive disorder where there is a lack of melanin. Andrea and her husband Claude both have normal skin pigmentation. Andrea’s mother has the albino phenotype, but her father and her brother do not (normal pigmentation). Claude’s parents are both normal, but he has a sister who has the condition (is albino). Answer the following questions Determine the genotypes for Claude, Claude’s parents, and sister. NOTE: Draw a punnet square or show your work.
A woman homozygous for normal height, with freckles, almond-shaped eyes, small nose, and Type A blood, has a Type O mother with no freckles and a type AB father with round eyes. She is engaged to a man with achondroplasia, round eyes and medium sized nose. Unlike his father, hismother is of normal height. Both his parents have Type O blood but nobody from both sides of his family has or had freckles. a. Write the COMPLETE genotypes of the man and the woman. Clearly indicate which genotype belongs to whom. b. Based on their genotypes, what is the probability that they will have: b.1 a child with Achondroplasia? b.2 a child of normal height? b.3 a child with type AB blood? b.4 a daughter with round eyes, freckles, and medium sized nose? b.5 a son with almond eyes, no freckles, and small nose?b.6 a daughter with same genotype as the woman? b.7 a son with same genotype as the man?
A son with cystic fibrosis is born to a couple that appears normal. What are the chances that any child born to this couple will have cystic fibrosis? If this couple had three normal children, what are the chances that the fourth child will have cystic fibrosis?
