- . Certain people are able to taste the chemical phenylthiocarbamide (PTC) when it is present in wet filter paper. These people are called 'tasters'. Others are unable to detect PTC and have the 'nontaster' phenotype. PTC tasting is an example of variation in sensory perception, and the genetic basis is thought to be rather simple. The ability to taste PTC is attributed to a dominant allele, denoted T, located on chromosome 7. The recessive allele is designated t. From analysis of pedigrees, 259 taster children and 278 non taster progeny were observed where one parent was heterozygous and could 'taste' PTC and the other parent was a 'nontaster'. Does this data set support the suggestion that his variation is due to a simple Mendelian pattern?What kind of evidence would indicate that the ability to taste PTC is inherited? Why was it important for Snyder to verify that males and females had similar proportions of tasters and non-tasters? Why do couples who can taste PTC have children who cannot?8. Bob is color blind, but he knows that neither of his parents were color blind. He is wondering if he received the gene for color blindness from his mother, his father, or both of his parents. What would you tell Bob? Show a Punnett square to prove your answer!
- A young boy is colorblind. His one brother and five sisters arenot. The boy has three maternal uncles and four maternal aunts.None of his uncles's children or grandchildren are colorblind. Oneof the maternal aunts married a colorblind man, and half of herchildren, both male and female, are colorblind. The other auntsmarried men who have normal color vision. All their daughters havenormal color vision, but half of their sons are colorblind.1. Which of the boy's four grandparents transmittied the gene forcolorblindness?2. Are any of the boy's aunts and uncles colorblind?3. Are either of the boy's parent colorblind?There are some genetically inherited taste impairments that vary in their severity. Hypogeusia is a partial loss of taste and individuals lack the ability to taste one of the five basic tastes. Less common than hypogesuia is ageusia, the complete loss of taste detection. You are a clinical geneticist and have found a family with a history of ageusia. Which of the following genes should you test for a mutation in patients with ageusia. a. Olfactory receptor protein P2 b. Adenylyl cyclase c. Phosphodiesterase d. Phospholipase C e. Taste receptor type 2 (T2R)5. The ability to taste PTC paper is controlled by a dominant gene. The ability to taste (T) PTC is 1ueunuop sno8Ázounu ae RIR dominant over the inability to taste (t) PTC. Normal skin (N) is dominant over albino skin (n). Two tasters, normally pigmented, have an albino son and a non-taster daughter. Show the cross between the parents. Genotype of mom Genotype of dad Genotypes Phenotypes What is the chance that the albino son is a taster? What is the chance that the non-taster daughter is an albino? What is the chance that the non-taster daughter is a carrier of the albino trait? What is the chance of getting offspring who are heterozygous for both traits?
- how can one female twin can have red-green colour blindness while her identical twin can distinguish colours accurately?1. You are recording from four separate ganglion cells, whose receptive fields are represented in the image below. All of these ganglion cells are center-on cells. Note: in this image, grey represents light (sorry, it's a little confusing, but it's hard to represent light in a black and white static image!). A B D (a) (1 point) What are the first order cells that make up each receptive field? (b)(1 point) What is the response of the first-order cells in the center of cell A when light shines on that area? (c) (1 point) Is the response you described in (b) different for the first-order cells that make up the surround of cell A when light is shining on them? (d) (3 points) Describe what accounts for the difference in the response of ganglion cells B and C. Be specific and be sure to include the role of all relevant interneurons.8. About 70% of people get a bitter taste from the chemical phenyl thiocarbamide (PTC), while the other 30% do not. The ability to taste this chemical (T) is a dominant characteristic, while taste-blindness to it is recessive (t). Tongue-rolling ability is dominant (R), while the inability to roll the tongue is recessive (r). A tongue-rolling woman who is taste-blind for PTC has a father who could not roll his tongue but could taste the PTC chemical. She marries a man who can taste PTC but cannot roll his tongue. His mother was taste-blind to the chemical. Show the possible children this couple could produce.

In dogs, there is a hereditary deafness caused by a recessive gene (d). A kennel owner has a male dog that she wants to use for breeding purposes if possible. The dog can hear, so the owner knows his genotype is either DD or Dd. If the dog's genotype is Dd, the owner does not wish to use him for breeding so that the deafness gene will not be passed on. This can be tested by breeding the dog to a deaf female (dd). Draw the Punnett squares to illustrate these two possible crosses. List all genotypes and phenotypes showing how many of the offspring would be normal and deaf.Which cross-modal pairing is likely to have the smallest effect on what we taste?
