Jonah and Jana are siblings. Jonah has the genetic disorder cystic fibrosis, caused by inheriting one copy from each parent of a mutation in the CF gene (the "mutant allele" of the CF gene). Jana does not have cystic fibrosis. Which of the following statements is/are true? Jana has two copies of the CF gene. Jana has two copies of the mutant allele that causes cystic fibrosis. Jana does not have the CF gene. Jana has at least one copy of the non-mutant CF allele. 00 0 0

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.
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.
Sickle-cell disease is an autosomal recessive genetic disorder. How many mutated hemoglobin alleles do people with sickle-cell disease have?
If someone has Marfan syndrome, what are their genotypes? If that person has children who do NOT have the syndrome, what are the children's genotypes?
Cystic fibrosis (CF) is an autosomal recessive trait (a). Assume that Emily (who has CF) decides to have children with a man who does not have CF and who is not a carrier of CF. What are their genotypes, and what is the probability that they will have a child who is a carrier for CF?
Cystic Fibrosis (CF) is an autosomal recessive condition. Therefore, heterozygous (Cc) carriers do not display symptoms. Two parents who are carriers plan to start a family and you are a genetic counselor helping to advise them about their chances of having children affected by CF. a) Suppose the couple has 4 children, each one year apart. What is the probability that all 4 children will inherit CF? b) What is the probability that any 3 of their 4 children will not inherit CF, but 1 will be affected? c) What is the probability that their first child will not inherit CF, but the younger 3 children will inherit CF?
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.
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?
If a person is heterozygous for cystic fibrosis is married to someone who actually has the disease. What are the chances that their child will have CF?
Do you think a patient needs to have the SAME two mutant alleles of CFTR to present with/have cystic fibrosis? Why or why not?
Sickle cell anemia is caused by an individual carrying two recessive copies of the hemoglobin gene (hemoglobin gene is labeled Hb, and the recessive version is Hbs). Thus, to have sickle cell anemia, a person must have the genotype HbSHbS. A person that is HbAHbA carries two copies of the normal hemoglobin gene and does not have sickle cell anemia. A person that is heterozygous (HbAHbS) produces enough normal hemoglobin to not have sickle cell anemia but is also resistant to malaria. People that are heterozygous are called “carriers” because they carry the recessive allele but do not express the recessive phenotype. a. A couple are both resistant to malaria but do not have sickle cell anemia. Draw a Punnett square to represent this cross. b. What is the probability that the couple has three children where one child does not have a recessive allele, one child is resistant to malaria and does not have sickle cell anemia, and one child has sickle cell anemia?
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
