Textbook Question
Chapter 9, Problem 13SQ
Incomplete dominance is seen in the inheritance of hypercholesterolemia. Mack and Toni are both heterozygous for this character, and both have elevated level of cholesterol. Their daughter Katerina has a cholesterol level six times normal; she is apparently homozygous, hh. What fraction of Mack and Toni’s children are likely to have elevated but not extreme levels of cholesterol, like their parents? If Mack and Toni have one more child, what is the probability that the child will suffer from the more serious form of hypercholesterolemia seen in Katerina?

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?
Tongue rolling is an autosomal dominant trait. What would be the phenotype of a person who is heterozygous for this trait?

- One form of familial hypercholesterolemia (FH) shows incomplete dominance. Homozygous dominant individuals (HH) have normal cholesterol, heterozygous individuals have mildly elevated cholesterol and homozygous recessive individuals (hh) have severe FH. If a woman with mild disease marries a man with no FH, what percent of their children will have severe FH? What percent will have mild FH? What percent will be normal? A man with severe FH has three children with a woman who does not have the condition at all. What are the phenotypic ratios of the offspring?arrow_forwardHemophilia is a sex-linked recessive trait. A male hemophiliac and phenotypically normal female have a son with hemophilia. They would like to have one more child. What is the probability of having a child without hemophilia? Explain using a Punnett square. Is it possible for a girl to be born with hemophilia? Explain.arrow_forwardA form of hemophilia is caused by a sex-linked (X-linked) recessive gene.

- What are the odds of the person with sickle cell anemia disorder passing it on to their children if the other person is homozygous dominant, heterozygous, or homozygous recessive for the trait?arrow_forwardHaemophilia A is a severe coagulation disorder that shows X-linked recessive inheritance. Red-green colour blindness also shows X- linked recessive inheritance. A man with both haemophilia A and colour blindness is referred for genetic counselling. Assume that his partner is not a carrier of either of these conditions. Which of the following is correct? OA. The probability that each of his daughters will be a carrier of haemophilia A is 1 in 2. OB. The probability that each of his sons will be affected with haemophilia A is 1 in 2. OC. he probability that each of his daughters will be a carrier of haemophilia A and colour blindness is 1 in 2. D. The probability that each of his sons will be affected with both haemophilia A and colour blindness is 1 in 2. OE. The probability that each of his daughters will be a carrier of both haemophilia A and colour blindness conditions is 1.arrow_forwardSickle cell anemia is inherited as an autosomal recessive condition. It also exhibits incomplete dominance in that the heterozygous genotype displays a mild form of the disease known as sickle cell trait while individuals with the homozygous recessive genotype have a severe form of SCA. A man who has severe sickle cell anemia marries a woman who suffers from a mild trait. What is the probabilitu they will have a child with severe SCA?What is the probability they will have a child with mild SCA? What is the probability they will have a normal child?

- Charles has achondroplasia dwarfism (autosomal dominant) but his wife is normal. What is the likelihood that they will have a child with achondroplasia dwarfism? What is the likelihood that they will have embryos that will die from achondroplasia dwarfism? Please explain.arrow_forwardSickle cell anemia is an inheritable red blood cell disorder that results in sickle-shaped red blood cells. The sickle-shaped red blood cells can stick to blood vessel walls and cause a blockage or slow the movement of blood throughout the body. Individuals who are heterozygous produce both normal and sickle-shaped red blood cells which gives them resistance to malaria but they do not develop sickle cell anemia (so heterozygotes are unaffected on the pedigree).Let HbS be the allele for sickle cell anemia and let HbA be the allele for normal red blood cells. Which of the following rows provides the correct genotypes for individuals I-2, I-4, II-1, and III-1? Select one: a. I-2 I-4 II-1 III-1 HbA_ HbAHbS HbAHbS HbA_ b. I-2 I-4 II-1 III-1 HbA_ HbAHbS HbAHbS HbAHbS c. I-2 I-4 II-1 III-1 HbAHbS HbAHbS HbAHbS HbAHbS d. I-2 I-4 II-1 III-1 HbAHbA HbAHbA HbAHbA HbAHbAarrow_forwardSickle anemia is a favorable mutation. There is only one amino acid different in sickle haemoglobin (S) as compared with normal haemogloblin (A). Persons with sickle cell trait (AS) are able to survive in malarious areas. A couple each having sickle cell trait have five children. What is the probability that they will have a child with sickle disease?arrow_forward
- Fred, a male, is affected with Lalaphobia. Fred's father is also affected with Lalaphobia; but his mother is unaffected. Fred marries Ginger (a female), who is unaffected, and they have four children: An affected son An unaffected son An affected daughter An unaffected daughter Ginger is pregnant with a fifth child, a son. What is the probability that this son will be affected by Lalaphobia? Assume Lalaphobia is a rare disease. Your answer should be a whole number between 0 and 100. For example, if you enter 33, it means you think there is 33% chance that the son will be affected by Lalaphobia.arrow_forwardRonnie is convinced that baby Charlotte must be his daughter. He has heard about something called the “Bombay blood type”, and he is convinced that this phenomenon could explain how he could be Charlotte’s father. Please explain the Bombay blood type and its implications in this SPECIFIC situation, including (i) how it arises and (ii) genes involved, (iii) who would have the Bombay blood type in this scenario, and (iv) could Ronnie be Charlotte’s father, if this was present? Also (v) how could you determine whether the appropriate person actually had the Bombay blood type? Please LABEL the parts of your answer (i), (ii), (iii), (iv), and (v).arrow_forwardhemophilia is a sex linked recessive disease. Dick does not have hemophilia. His wife Debi is a heterozygote. They are having fraternal twins, one of each sex, who they have named Dick Jr. and Debi Jr. What are the chances of Dick Jr. having hemophilia? Debi Jr.?arrow_forward
