Nail-patella syndrome gene is 10 map units from the I gene that determines the ABO blood type on chromosome 9. John’s afflicted mother is type A, while his normal father has type O blood. The Laura’s afflicted mother has type O blood, while her normal father has type B blood. What is their chance of having a normal, type O child.
Select the true statements. (can be multiple). Sperm and egg cells are diploid, meaning that they have two copies of the human genome. Somatic cells are haploid, meaning that they have one copy of the human genome. Stem cells are haploid, meaning that they have one copy of the human genome. Somatic cells are diploid, meaning that they have two copies of the human genome.
Achondroplasia is a form of dwarfism in humans. It is caused by a mutant allele of the fibroblast growth factor receptor 3 gene ( FGFR3) that produces an overactive protein. Having one copy of the mutant allele results in dwarfism. Two copies of the mutant allele results in death before birth. If a man with Achondroplasia marries a woman who is Sickle Cell Anemia carrier and they have a child together, what is the probability that their child will Achondroplasia AND be a Sickle Cell Anemia carrier? ½ 2/3 ¼ 1 ½ 1/16
Imagine that you are in your late 30s or early 40s and decide that you want a child. You realize that you’re at greater risk of having a child with Down’s Syndrome. What sorts of genetic screening are available today? If you find out that this child has this condition, do you think it’s appropriate to have an abortion? Why or why not? Question: Does elective abortion of fetuses with physical or other developmental disabilities have an effect on the perception of personhood, dignity, and rights in society? Explain.
The questions below all refer to the following pedigree. The locus for allele D/d determines how cilia function within the body. Mutations at this allele cause abnormal ciliary function, resulting in a clinical disorder characterized by frequent respiratory infections (including in the ears, sinuses, and lungs), as well as infertility. In the pedigree, black circles/squares represent individuals affected by the disorder. White circles/squares represent unaffected individuals. Remember, if a trait is rare in a population (such as this one), we assume individuals marrying into the family are NOT carriers unless the information provided indicates otherwise.

Three people are diagnosed with different types of cancer. One is a lifelong smoker and has lung cancer, one has active Crohn disease and colorectal cancer, and the other is a farmer with newly diagnosed melanoma. What do these individuals have in common?
In people the gene, which causes one form of color-blindness or Daltonism, is located in the X-chromosome. The affected condition is caused by a recessive gene, healthy condition is dominant. A girl who has emmetropia (normal eyesight), whose father had color-blindness, marries a normal man, whose father also suffers from color-blindness. What kind of sight is expected in the children from this marriage?
Both have a genetic disorder, but they already have one child who does not have the disorder. They would like to have more children and were told by a friend that since their first child was normal their future children would be normal as well. Explain to them the probability of future offspring being normal or having the disease (assume that this is an autosomal disease). Be sure to tell them whether the disease is brought about by a dominant or recessive allele and what fraction of their children (if any) could be carriers for the disease.
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 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…
