A couple named Bob and Brené have 2 children: Angela (female) and Arnold (male). Arnold has sickle cell anemia, a disorder that arises from two recessive alleles of the beta globin gene. Genetic tests have revealed that Bob’s father Denzel has the recessive allele, but Bob’s mother Diane does not. Brené’s father Charlie does not have the recessive allele and her mother Candie was never tested, so we don’t know her genotype. A) Draw out the pedigree for this family and indicate each person’s name. Write out all the possible genotypes for each person (use “A” to represent a dominant allele of the gene and “a” to represent a recessive allele of the gene) and the probability that each person is each of those genotypes.

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 If Andrea and Claude are carriers for the albino allele, what is the probability that they have an albino child? If Andrea and Claude have a second child, what is the probability this child be normal (non-albino)? NOTE: Draw a punnet square or show your work.
A young couple went to see a genetic counselor because each had a sibling affected with cystic fibrosis. (Cystic fibrosis is a recessive disease and neither member of the couple nor any of their four parents is affected). What is the probability that the female of this couple is a carrier and what are the chances that their child will be affected with cystic fibrosis?
At the beginning of the film, you were introduced to Davaun and Skyy Cooper, who both have sickle cell disease. Which of the following must be true about their parents? Group of answer choices One parent has at least one copy of the sickle cell allele. Both parents have at least one copy of the sickle cell allele. Both parents have sickle cell disease. One parent has sickle cell disease.
Armin and Annie are going to have a baby. Annie has dimples in her cheeks (a dominant trait), while Armin does not. You know that Annie's father has dimples in both cheeks, while her mother does not. Her mother must have the recessive trait. Annie's father has the dominant trait, but you don’t know if he is a homozygote or heterozygote. But you still know what Annie’s genotype must be because Annie must have a recessive allele since that is all she could have inherited from her mother. Since Annie has a dimples you know she inherited a dominant allele from her father. What are the chances Armin and Annie’s baby will have dimples? Determine the Phenotype and Genotype and its probability. Show your solution in a clean sheet of paper.
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. Some individuals who are homozygous for this autosomal recessive gene experience only skin discoloration and joint pain, others experience heart disease in addition to the skin discoloration, still other individuals suffer also suffer from diabetes, severe heart disease, and liver damage. Name and define this genetic phenomenon and explain how it relates to this specific genetic situation described above.
Tay-Sachs disease is a recessive genetic disease. Two individuals, both of whom are heterozygous for a recessive allele that causes the disease have one child who does not 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…
Geneticists are concerned about three different genetic conditions present within their family. Achondroplasia is an autosomal dominant genetic disorder that results in short-limbed dwarfism. (A = achondroplasia allele; a = average height allele). Red-Green Color blindness is an X-linked recessive genetic disorder (Xc = color blindness allele; XC = normal color vision allele). The 7-year-old son has an autosomal recessive form of deafness. (h = deafness allele; H = normal hearing allele.) All three family members were karyotyped, and additional genetic testing was performed to determine the chromosomal location of the genes being studied. The figures below show the karyotypes of the mother and father with respect to the chromosomes containing the three genes mentioned above. Question: The couple’s 7-year-old son has all three of these genetic conditions (achondroplasia, color blindness and deafness). Taking into consideration the genotypes of his parents, what is the complete…
Tony has anosmia, a disorder that prevents him from being able to smell. This disorder is an X-linked recessive condition. Tony's wife Samantha has a normal sense of smell. Tony's sister Hailey also has a normal sense of smell as does her husband Phil and daughter Sandra. However, Hailey and Phil also have identical twin boys, Josh and Andre, and neither of them can detect odors. Tony and Hailey's parents, Tom and Dolores can smell normally. Draw a pedigree for this family indicating the individuals who must be carriers of the anosmia mutation as well as the genotype of each individual. Take a photo of your pedigree and upload it to this question.
A woman knows that her mother is a carrier of Kartagener’s syndrome (an autosomal recessive disorder). The woman does not know if either she or her husband are carriers. The couple wants to have a child, but is worried about whether or not they could have a child with Kartagener’s syndrome. Should the couple seek the advice of a genetic counselor? In other words, is there a chance they could have an affected child? If there is a chance, please make sure your answer includes the specific parental genotypes necessary to make this possible.
