  6. GENETICS Review

  7. Genetics DNA, RNA and Protein Synthesis DNA and Proteins Mendel Genetics Complex Inheritance

  8. Section 3 Check Question 1 Any change in DNA sequences is called a _______. A. replication B. mutation C. transcription D. translation The answer is B. IN: 1.24

  9. Section 3 Check Question 2 Which is more serious, a point mutation or a frameshift mutation? Why? Answer A frameshift mutation is more serious than a point mutation because it disrupts more codons than a point mutation. IN: 1.24

  10. Gen • Two heterozygous gold marigolds are crossed. What is the expected phenotypic ratio of the offspring? Gold is completely dominant over red. • all red • all gold • 1 gold : 1 red • 3 gold : 1 red

  11. Gen • A salamander lost a portion of its leg in a fight. What molecule contained all the information necessary to make a new leg? • protein • DNA • thymine • lipid

  12. Gen • Which of the following statements about mutations is true? • Mutations are always harmful to the individual. • Mutations can be important to the evolution of a species. • Mutations that occur in gametes are NOT passed on to future generations. • Mutations that occur in somatic cells are passed on to the future generations.

  13. Gen You’ve been hired as a genetic counselor for Bates hospital. Your first clients are the parents of a child with Phenylketonuria, PKU. The PKU gene is located on chromosome #12. Individuals with PKU are missing an enzyme needed for metabolism. They can develop severe mental retardation if untreated. The parents do NOT have PKU and neither do their other two children.

  14. Gen • The parents want to know how their child got PKU. Which of the following is the best response? • Both the parents carry 2 alleles for PKU which were passed on to the child. • Both the parents carry 1 allele for PKU which was passed on to the child. • One parent carries an allele for PKU which was passed on to the child. • Neither parent carries an allele for PKU, so the child must have gotten it some other way.

  15. Gen • Which of the following statements about PKU is true? • PKU is caused by the environment. • PKU is a sex-linked disorder. • PKU is a dominant disorder. • PKU is a recessive disorder.

  16. Gen British scientist Ronald Fisher stated, “Mendelism supplied the missing parts of the structure erected by Darwin.” Explain what Fisher meant by this…..

  17. Gen • Mutations that occur in gametes _______. • may be passed to offspring. • occur during mitosis. • occur during fertilization. • are usually fatal.

  18. Gen • The genetic code is carried in DNA molecules through the sequence of…. • bases • sugars • helicases • phosphates

  19. Gen • Mutations that occur in body cells are passed to…… • gamete cells. • somatic cells. • female offspring. • male offspring.

  20. Gregor Mendel Who is the “Father of Genetics”? When 2 alleles DON’T BLEND but BOTH SHOW TOGETHER like in A B blood type, it is called _______________ codominance

  21. heredity Transmission of characteristics from parents to offspring is called ___________________. _____________ is the study of how characteristics are passed on from one generation to the next. Genetics

  22. RECESSIVE __________________ = An allelethat IS MASKED BY the presence of another allele The appearance of an organism is its _____________ phenotype

  23. hybrid Another name for heterozygous The diagram at the right is called a _____________ Punnett square

  24. DOMINANT __________________ = An allele that MASKS the presence of another allele Red and white flowers producingpink offspring is an example of _______________________ Codominance incomplete dominance Incomplete dominance

  25. lower case A recessive gene is represented by a _________________ letter. What phenotypic ratio would youexpect to see in offspring from a monohybrid cross of 2 heterozygous parents? 3:1 Dominant:recessive

  26. ALLELES _______________ are different gene choices for a trait.

  27. capital A dominant gene is represented by a ____________ letter.(usually the first letter of the trait) When a heterozygous individual shows a blending of 2 alleles instead of one being dominant over the other it is called ___________ ____________. Incomplete dominance

  28. HOMOZYGOUS PURE When both alleles in the pair are the SAME the organism is _______________ or __________ What phenotype ratio is a clue that there has been a dihybrid cross between 2 heterozygous parents? 9:3:3:1

  29. Red An Rr organism would have ____________ flowers if this trait was COMPLETELY DOMINANT. R = red flowers r = white flowers pink An Rr organism would have ____________ flowers if this trait was INCOMPLETELY DOMINANT. BOTH red & white An Rr organism would have ______________ flowers if this trait was CODOMINANT.

  30. Law of SegregationLaw of Independent Assortment What are Mendel’s 2 laws of heredity? The offspring of the P1 generation are called the ____ generation F1

  31. flower color in Four o’clocks Explain and Give an example of a trait that shows incomplete dominance TRUE or FALSEA person with Type O blood could be a blood donor for a person with Type AB blood. True; Type O is the universal donor

  32. HETEROZYGOUS HYBRID When both alleles in the pair are DIFFERENT the organism is _________________ or _____________ A cross that involves only 1 trait is called a ____________ cross. monohyrid

  33. T = Tall t = short The genotype of the offspring from the cross at the right is _________. Their phenotype is _________. Tt tall

  34. Which of the following genotypes is homozygous? TT Ww Bb rr mm BB Tt TT rr mm BB Another name for homozygous is ________. pure

  35. Which of these Punnett squares would you use to predict the offspring of a DIHYBRID cross? This one!

  36. red In the cross at the right __________ is dominant for flower color. Which of the following genotypes is from a heterozygous organism? Tt SS bb Mm Rr kk Tt Mm Rr

  37. DNA A gene is a segment of _______ that codes for a trait. The Law of Segregation and theLaw of Independent Assortmentare the result of the movement of chromosomes during ___________ mitosis meiosis meiosis

  38. dihybrid The Punnett square below shows a ___________ cross. homozygous monohybrid dihybrid test

  39. Crossing a red haired horse with a white haired horse produces a roan colored horse. (Both alleles for hair color show together). This kind of inheritance is called ___________________ Co-dominance

  40. Homozygous recessive What type of genotype is used to make a test cross? What type of gametes can this organism produce? BbTt ______ ______ _______ _______ BT bt bT Bt

  41. In guinea pigs, black fur (B) is dominant over brown fur (b). If a black Guinea pig is crossed with a brownGuinea pig and the litter contains a brown baby, the genotype of the black parent is probably BB Bb bb Bb; Must have one B to be black must have one b to pass on to baby

  42. Which of these Punnett squares would you use to predict the offspring of a MONOHYBRID cross? This one!

  43. F1 Crossing individuals from the P1 generation produces the ____ generation. A gene is a segment of ______. DNA PROTEIN RNA CARBOHYDRATE DNA

  44. Blue An Rr organism would have ____________ legs if this trait was COMPLETELY DOMINANT. L = Blue legs l = yellow legs green An Rr organism would have ____________ legs if this trait was INCOMPLETELY DOMINANT. BOTH Blue & yellow An Rr organism would have ______________ legs if this trait was CODOMINANT.

  45. F2 Crossing individuals from the F1 generation produces the ____ generation. A person with this type of blood could DONATE to Type __________blood A or AB

  46. In a monohybrid cross of two HETEROZYGOUS parents (Pp), you would expect the offspring to be: 1 pp:3 PP 3 Pp:1 pp 1 PP:2 Pp:1 pp all Pp

  47. G g The parents in this cross are _____________ Homozygous Heterozygous Heterozygous G g If G is dominant for green pods and g is recessive for yellow pods, what percentage of the offspring will have green pods? _______% 75

  48. The genotype of the offspring in the blue box is _______ bb The offspring in the blue box is homozygous heterozygous homozygous

  49. In guinea pigs black fur (B) is dominant over brown fur (b). The Punnett square for a cross between a HETEROZYGOUS black guinea pig and a PURE brown guinea pig would look like This is the Correct setup Heterozygous = Bb Pure brown = bb homozygous Another name for pure is _________________

  50. R r • r • r Red throats (R) are dominant over white (r) throats in Goonie birds. Make a cross between a PURE RECESSIVE and a HETEROZYGOUS Goonie bird. Rr rr Rr rr What are the possible phenotypes of their offspring? (% and color) 50% red throats 50% white throats
