A study of three generations in a family of a male colleague of the authors indicated that many of the man's blood relatives had died of cardiovascular accidents and coronary heart disease. Others died of other causes but were affected by high blood pressure. What are the implications of this information for the man in question?
b. What information and help might a genetic counselor provide?
Explain why conditional alleles are important when we want to study lethal mutations.
A farmer wants to breed a variety of taller corn.a) How can the farmer use variation in the height of thecurrent corn plants to produce taller corn plants?b) Will the farmer's work be most effective if height incorn plants is determined by polygenic inheritance,multiple alleles, or co-dominant alleles? Explain.c) The farmer finds that many of the tallest corn plantsare also very susceptible to a particular disease. Howcould the farmer design an experiment to find outif the genes for height are linked to the genes forresistance to the disease?d) If these genes are linked, what steps could the farmertake to create a breed of corn that is taller and moredisease-resistant than the current corn crop?

- 1.) A farmer wants to breed a variety of taller corn. a) How can the farmer use variation in the height of the current corn plants to produce taller corn plants? b) Will the farmer’s work be most effective if height in corn plants is determined by polygenic inheritance, multiple alleles, or co-dominant alleles? Explain. c) The farmer finds that many of the tallest corn plants are also very susceptible to a particular disease. How could the farmer design an experiment to find out if the genes for height are linked to the genes for resistance to the disease?arrow_forwardForward mutations A change a wild-type allele to a different allele. B changes and mutant allele back to wild-type. C causes no change in phenotype.

- Which of the following is a characteristic of paramutation? a. One allele is able to alter another allele when both are present in a heterozygote. b. Altered alleles must be passed on to future generations. c. Altered alleles must be capable of altering other alleles in future generations. d. All of the above.arrow_forwardYou find a person that has a new allele that is not found in DNA samples taken from skin cells of the mother or the father, suggesting that the mutation arose during the formation of the gametes that formed this person. Is it more likely that the mutation was present in the sperm or the egg that formed this person and why do you believe this is the case?”arrow_forwardWhy is it that the allele coding for darker skin did not evolve to protect us from skin cancer? A. Darker skin did develop to protect us from skin cancer B. Because skin cancer usually develops before an individual's reproductive years, so it doesn't affect the ability for someone to pass on their genes. C. Because skin cancer isn't harmful D. Because skin cancer usually develops after an individual's reproductive years, so it doesn't affect the ability for someone to pass on their genesarrow_forward
