A) Using all available information, what is the correct inheritance pattern of this trait? Why? B) Draw the pattern that would result for DNA amplification of individual I-2 in the empty lane of the gel. C) What is the probability if individual IV-1 mates with an affected male that their offspring will be an affected female? D) What is the genotype of individual II-2?

A couple comes into the family counseling center and wants information on genetic counseling. They are thinking of starting a family but the wife has a family history of Tay Sachs disease. Kieran is a genetic counselor who will explain the services available at the center. Kieran’s discussion will include genetic mutation, tests that may be done during pregnancy, and advances being made in genetic therapy. What information can Kieran give the couple regarding the services of the genetic counseling center?

Would you be able to draw a circular map of the seven genes? I have trouble with correct position of the genes

A genetic variant is associated with high penetrance and low expressivity. This means the variant is associated with a:   Question 15 options:   High chance of showing disease symptoms and the disease is caused by a rare mutation.   High chance of showing disease symptoms but the symptoms will be mild.   Low chance of showing disease symptoms and the symptoms will be mild.   High chance of showing disease symptoms and the symptoms will be severe.   Low chance of showing disease symptoms but the symptoms will be severe.

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…

Huntington disease (HD) can arise from a rare, short, in-frame addition of CAG nucleotide triplets within the huntingtin (HTT) gene coding region, which creates a disease-causing allele with the symptoms only appearing later in life. Using this information, describe an experiment that could be undertaken to determine whether a currently healthy young individual is a carrier of the HD-causing mutation. Describe the method you would use and how you would interpret the results of this experiment.

Please help solve questions 9 and 10, thank you.
