Skin cancer requires a number of mutations, several of which are often caused by the sun in individual skin cells. With this is mind, if you develop melanoma (skin cancer) on your arm, will you pass on that same melanoma to your offspring? Why or why not? Explain in your own words.

Lauren has chronic bronchitis and frequently ends up hospitalized with pneumonia. She has no family history of cystic fibrosis, a serious recessive genetic disorder which affects respiratory and digestive tracts. She and her husband Nat have one child after undergoing fertility treatments to overcome Nat's infertility. They are surprised when their child is diagnosed with cystic fibrosis and the genetic counselor tells them that they each also have the condition, which causes their bronchitis and infertility. Which of the following would be a reasonable explanation of their situation? Although the underlying disease is genetic, the severity of the disorder if influenced by environmental variation. Cystic fibrosis displays variable expressivity. There are different alleles of cystic fibrosis which cause differing forms of the disease. There are different alleles of cystic fibrosis which cause differing forms of the disease and Cystic fibrosis displays variable expressivity are the only…

Marfan’s syndrome is a disorder of the fibrous connective tissue, characterized by many symptoms, includinglong, thin digits; eye defects; heart disease; and long limbs. (Flo Hyman, the American volleyball star, suf-fered from Marfan’s syndrome. She died from a ruptured aorta.) a. Use the pedigree above to propose a mode of in-heritance for Marfan’s syndrome. b. What genetic phenomenon is shown by this pedigree?c. Speculate on a reason for such a phenomenon.

On an island with no large predators, some ducks are born with a mutation that gives them stubby little wings. These ducks can’t fly, but there’s really no need to fly since there are no predators. In fact, they have an advantage because they don’t have to eat as much to support those big wings like the other ducks. Over time, the flightless ducks reproduce better than the regular ducks, and eventually all the regular ducks die out. What characteristic of life is being demonstrated here?

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. A1 A2 II B1 B2 B3 B4. B5 B6_ II C1. C2 C3. C4. C5 IV D1. D2, D4 . D5 Individuals C2 and C3 are considering having additional children. However, having already had a child with this disorder, they visit a genetic counselor to determine what the probability is that their future child would have the disorder. If C2 and C3 have another…
