In man, muscular dystrophy is a condition in which the muscles waste away during early life and may result in a shorter life expectancy. It is due to a sex-linked, recessive gene. A certain couple has five children – three boys (ages 1yr, 3yrs, and 10yrs old) and two girls (ages 5yrs and 7yrs old). The oldest boy shows the symptoms of this disease. You are their family physician and they come to you for advice. What would you tell them about the chances of their other children developing the disease?
Which of the following is the correct progression from Mendel's heritable "factors" (genes) to the actual phenotype of a eukaryotic organsim? Multiple Choice Gene -> RNA -> MRNA -> Ribosome -> Protein -> Phenotype Gene -> FRNA -> Ribosome -> TRNA -> Protein -> Phenotype Gene -> RNA -> Phenotype -> Protein Gene -> RNA -> Ribosome -> Protein -> Phenotype Gene -> DNA -> RNA -> Ribosome -> Protein -> Phenotype
A couple is planning a family, but since each has a brother having the sickle-cell disorder, they are worried that their kids might develop the disorder too. Neither of them nor their respective parents have the disorder. Which of the following will be your smartest advice as a genetic counsellor? One of four of their children can be expected to have sickle cell. It is possible that none of their kids will have the disorder, but tests should be carried out on both of them to confirm. All of their children will have sickle-cell disorder. There is no chance of any of their kids having sickle cell.

Which of the following inheritance patterns was observed, in the experiments of Alfred Hershey and Martha Chase, using the T2 bacteriophage of Escherichia coli? radioactive proteins were passed on to viral progeny, but not radioactive polynucleotides radioactive polynucleotides were passed on to viral progeny, but not radioactive proteins both radioactive proteins and radioactive polynucleotides were passed on to viral progeny both radioactive polynucleotides and radioactive proteins were passed on to viral progeny neither radioactive proteins nor radioactive polynucleotides were passed on to viral progeny The Hershey / Chase experiments (above) demonstrated that the T2 bacteriophage uses: phosphate-containing molecules for its genetic material, but not sulfur-containing molecules sulfur-containing molecules for its genetic material, but not phosphate-containing molecules both phosphate-containing and sulfur-containing molecules for its genetic material both sulfur-containing…
Gene dosage is important for a number of genetic phenomenon. Name two and explain their relationship to the genotype and phenotype observed.
Regarding Mendelian inheritance in diploid individuals, (Read each statement carefully. Select all of the statements below that are true (that you agree with). Leave any statements that are false (that you do not agree with) un- selected.) a diploid individual receives two copies of every autosome from the previous generation. for every autosomal gene inherited by an individual, both copies can come from one parent. a diploid individual gives two copies of every autosome to a child in the next generation. to be diploid means that two independent genes are specified in the individual's genotype.
Photography booths that claim to produce pictures of what a male or female child of any given couple will look like are beginning to appear in arcades throughout the country. A couple enters the booth, a camera takes their pictures, and then a computer program analyzes and blends the morphologies of the two people to produce images of a male child and a female child they might create. In genetic terms, why will the couple be wasting their money if they buy these computer images? (Respond in at least 2 paragraphs)
To play Jeopardy, the answer is given. You must supply the question. Choose the best question for the following answer: Mutation in a second gene enhances the defects caused by a mutation in the first gene, leading to lethality. What is dominant negative? O What is suppressor? O What is recessive lethality? O What is synthetic lethal?
Why is it difficult to study whether a trait is due to epigenetic changes or due to something else? (Hint: What are the other things that may cause disease?) (Minimum of 2 complete sentences.)
A 20-year-old woman comes to your genetic counselling center because she knows that Huntington disease occurs in members of her family. Huntington is an autosomal dominant disease that often becomes apparent around 35–40 years of age. Her paternal grandfather was afflicted, but so far her 41 year old father shows no symptoms. Her two great-great grandmothers on her father's side were healthy well into their 90s, and one of her great-great grandfathers died of unknown causes at 45. Testing for Huntington disease is extremely expensive, but she is concerned that she may fall victim to this disease and wants to plan her life accordingly. After examining her pedigree you advise her to: not get tested because her father is only a carrier and it is very unlikely her mother is a carrier. not get tested because there is no possibility that she is homozygous. get tested because her father could be a carrier. not get tested because only males in her family get the disease. not get tested…
Imagine that you are a new breeder for caique parrots. You can sell normal green feather birds for $500 a bird. The mutation for blue feathers is rare and birds with this color can sell for $3000 a bird. Your goal is to produce as many blue feather offspring as you can, but you don't have the budget to buy blue feather birds as parents. Question: What genotype should you purchase for both parent blrds to get the best chance of getting blue feather offspring? Create and use your Punnett square results as evidence to support your answer. You will need to make multiple Punnett Squares to see which parent genotypes makes the most blue feathered offspring. Keep in mind that Green fealhers (G) is dominant over blue feathers (g), so birds with blue feathers have the genotype gg. Some Punnett squares are provided for you to determine the possible crosses, but remember yoU cannot afford a blue feathered bird, so neither of your parent birds can have the genotype gg.
