Chapter 14, Problem 17GP
Imagine that a newly discovered, recessively inherited disease is expressed only in individuals with type O blood, although the disease and blood group are independently inherited. A normal man with type A blood and a normal woman with type B blood have already had one child with the disease. The woman is now pregnant for a second time. What is the probability that the second child will also have the disease?

Duchenne muscular dystrophy is sex linked and usually affects only males. Victims of the disease become progressively weaker, starting early in life.a. What is the probability that a woman whose brother has Duchenne’s disease will have an affected child?b. If your mother’s brother (your uncle) had Duchenne’s disease, what is the probability that you have received the allele?c. If your father’s brother had the disease, what is the probability that you have received the allele?
In humans, the genetic disease cystic fibrosis is caused by a recessive allele (a). The normal (healthy) allele is dominant (A).
What is the genotype of someone who has cystic fibrosis?
What are the two different genotypes that a healthy person could have?
If two people were both heterozygous for the cystic fibrosis gene, what fraction of their children would be likely to have this disease? Hint: Draw a Punnett square to figure it out.
For a recessive condition, two normal heterozygous individuals have children.
What is the likelihood of their children being affected by this condition?
What is the likelihood of their children being carriers without the condition?
What is the likelihood of their asymptomatic children being carriers?
Suppose that an individual with the condition has children with a heterozygous individual, what is the likelihood of their children being carriers?

- Marfan syndrome is a disease caused by a rare dominant allele of the fibrillin-1 gene. Fibrillin-1 is an important component of the extracellular matrix, and people with the disease-causing allele have abnormal connective tissue. An affected mother (Marta) and an unaffected father (Joe) have one unaffected daughter (Luisa - she does not exhibit any traits of the syndrome). If Luisa has a child with Nico (unaffected), what is the probability that her child will inherit Marfan syndrome? Select one: a. 50% b. 25% c. 100% d. 0% e. 75%arrow_forwardIn humans, brown eyes (B) are dominant over blue. A brown eyed man marries a blue-eyed (b) woman and they have three children two of whom are brown-eyed and one of whom is blue-eyed. if the male has brown eyes but has a blue-eyed child, what must his genotype be?arrow_forwardOne form of the bleeding disorder known as von Willebrand disease is an autosomal recessive disease. A man who is a carrier marries a woman who is also a carrier of the disease. (a) What percentage of their children are likely to have a disease phenotype? (b) What percentage of their children are likely to have a normal phenotype? (c) What percentage of their children are likely to be carriers of the disease?arrow_forward
- Hemophilia is another example of an X-linked disease caused when a recessive allele (Xh) is expressed. If a normal male reproduces with a heterozygous normal female, what are the expected genotypes and phenotypes? Will any of their daughters develop hemophilia?arrow_forwardFor sex-linked recessive traits, only females can be “carriers”, like how both Diana and Olivia are carriers for hemophilia. Why can’t males be carriers for these traits?arrow_forwardIn humans, hypertrichosis of the ears is caused by a holandric gene while baldness vs. non-baldness is sex-influenced, controlled by a pair of autosomal alleles, and follows a male-dominant pattern of inheritance. Based on this information, can a normal non-bald daughter have a hypertrichosis bald father? Explain your reasoning and predict the genotypes.arrow_forward
- Wavy hair is intermediate to straight and curly hair. Similarly, medium-sized nose may be inherited if one parent has a large nose and the other parent has a small nose. James has wavy hair, large nose, and type A blood. His father is type O. What is the complete genotype of James? __________________ Nicole has straight hair, medium-sized nose, and type AB blood. What is the complete genotype of Nicole? __________________ Should James and Nicole marry, what is the probability that they will have a: Daughter with the same traits as Nicole? ______________ Son with the same traits as James? ____________________ Child with curly hair, small nose, and type O blood? _______arrow_forwardPorphyria is a genetic disorder caused by the inability to properly metabolize a component of hemoglobin. King George III is suspected to have been afflicted with this disorder. Assume that both George and his Queen suffered from this disorder and they had one afflicted child and one normal child. Is porphyria inherited in a dominant or recessive fashion? What must be the genotype of both George and his Queen? Using punnett square, show ALL work used to achieve your answer.arrow_forwardAssume that a gene controls the expression of a trait in which affected children occur only in families where one or both parents are also affected; children who are normal may have parents who are (1) both normal, (2) one normal and one affected, or (3) both affected. Is the gene for the affected condition completely dominant, co-dominant, incompletely dominant or recessive?arrow_forward
- The last Emperor of Russia, Nicolas II, was married to Empress Alexandra, and they had fivechildren, Olga, Tatiana, Maria, Anastasia, and Alexis. Alexis was the only one who was afflictedwith hemophilia or the royal bleeding disease; all other members were normal. Research on this medical condition and determine the mode of inheritance. If only Prince Alexis was afflicted with the disease, determine his genotype. What could be the genotypes of the Emperor and Empress? Is it possible that each daughter could have been a carrier?arrow_forwardIn humans, the ABO blood type is under the control of autosomal multiple alleles. Color blindness is a recessive X-linked trait. If two parents who are both type A and have normal vision produce a son who is color-blind and is type O, what is the probability that their next child will be a female who has normal vision and is type O?arrow_forwardHair texture is determined by gene c in an incomplete dominance inheritance pattern, where the heterozygous condition (c1c2) results in wavy hair. Hairline is controlled by gene H, where a widow's peak is dominant to a straight hairline. If a woman with curly hair and a straight hairline has a child with a man with a widow's peak and straight hair (his mom had a straight hairline), what is the chance they would have a kid that has exactly the same hair as mom? Draw the Punnett square and demonstrate the possible genotypes and phenotypes that could result from these two parents' mating.arrow_forward
