- A single allele gives rise to the HbS form of hemoglobin. Individuals who are homozygous for the allele HbS/HbS develop sickle-cell anemia Section 9.5. Heterozygous individuals HbA/ HbS have few Symptoms. A couple who are both heterozygous for the HbS allele plan to have children. For each of the pregnancies, determine the probability that their child will be: a. homozygous for the HbS allele b. homozygous for the normal allele HbA c. heterozygous: HbA/HbSCystic fibrosis is an autosomal recessive disorder that affects 1 in 3 000 newborns with Caucasian background.

- Cystic fibrosis (CF) is an autosomal recessive condition triggered by the overproduction of stickymucus that clogs the lungs and pancreas. It is a life-threatening disease, but medical advances helpedthe afflicted to live through adulthood.The mother of Claudia died from cystic fibrosis, but her father was normal and never had anyrelative with CF. Her fiancé, Marcus, turned out to be a carrier of the CF allele. What are the genotypes of Claudia and Marcus?

What are the genotypes of Claudia and Marcus? Claudia: ________________________ Marcus: _____________________ They planned to have four children. What is the probability that:a. all children will be normal b. at least two will be normalThe cystic fibrosis allele is recessive. The frequency of cystic fibrosis is 0.000484, or about one in 2000 people. Calculate the allele frequencies. What portion of people are carriers (heterozygotes) for cystic fibrosis?
- In a particular human family, John and his motherboth have brachydactyly (a rare autosomal dominant allele causing short fingers). John’s father hasHuntington disease (another rare autosomal dominant allele). John’s wife is phenotypically normaland is pregnant. Two-thirds of people who inheritthe Huntington (HD) allele show symptoms by age50, and John is 50 and has no symptoms.Brachydactyly is 90% penetrant.a. What are the genotypes of John’s parents?b. What are the possible genotypes for John? Howlikely is John to have each of these genotypes?c. What is the probability the child will express bothbrachydactyly and Huntington disease by age 50 ifthe two genes are unlinked?d. How will your answer to part (c) change if insteadthese two loci are 20 m.u. apart?A rare recessive allele inherited in a Mendelian mannercauses the disease cystic fibrosis. A phenotypically normal man whose father had cystic fibrosis marries a phenotypically normal woman from outside the family, andthe couple consider having a child.a. Draw the pedigree as far as described.b. If the frequency in the population of heterozygotesfor cystic fibrosis is 1 in 50, what is the chance that thecouple’s first child will have cystic fibrosis?c. If the first child does have cystic fibrosis, what is theprobability that the second child will be normal?Color blindness is typically an inherited genetic condition in which individuals have a decreased ability to see color or differences in color. Color blindness only occurs in individuals who have two recessive alleles for the condition. Normal color vision is due to a dominant allele (C) Color blindness is due to the recessive allele (c) a) If Susan is homozygous for normal vision, and Matt is homozygous for color blindness, what is the likelihood (in percentage) that their son Alex will have color blindness? Perform a Punnett Square (either below or by hand on paper) to find the probability. Provide your answer in a full sentence. If you did the Punnett Square by hand, attach your photo to the next question.
