Genetics ppt chap.14

  1. 1. Genetics PPT questions Awad AP Bio 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13. 14. 15. 16. 17. Who is Mendel? What do P and F generations stand for? What is self-pollination? Name 4 traits in pea plants that Mendel studied Explain what alleles are? What is the difference between a gene and an allele? How many alleles do organisms inherit for each trait? What is a dominant allele? What is a recessive allele? What are genotypes and phenotypes? If PP is crossed with pp what would be the genotype of the offspring? Cross 2 hybrid individuals Pp XPp, show the Punnett square What is Homozygous? What is Heterozygous? What is a testcross? What is the Mendel’s law of segregation?When does segregation occur? What is the difference between monohybrid and dihybrid crosses? What is the law of Independent assortment? This is true under what circumstances? What is an exception to Mendel’s second law? What is true about the genetics of peas? Genetics and probability 18. What laws do Mendel’s laws of segregation and Independent assortment follow 19. What is the chance that 2 or more independent events will occur together, or the probability of two coins that are tossed together will land heads up? 20. What is the probability of Pp x Pppp 21. What is the chi square test? 22. We will do Lab23ChiSquare (Kim Foglia) Beyond Mendel 23. Describe the simple system of heredity that Mendel found in the Pea plants 24. Is this a regular finding in heredity 25. What is Incomplete Dominance? 26. Cross a true breeding Red flower with a true breeding white flower 27. What is Codominance? Give an example 28. What are the IA and IB in Blood types? 29. Explain Blood compatibility 30. If a person has Blood type O which of the following statements is true: a) the person has no antigens A or Bon the surface of his blood cells, b) The person has no antibodies to A or B in his serum. 31. What is polygenic heredity? Give an example 32. What are sex-linked traits? Give examples 33. How many sex-linked diseases have been traced?
  2. 2. 34. 35. 36. 37. What are the main genes found on the Y chromosome? What is X inactivation and barr body? What is the molecular basis for inheritance? What is polydactyly? Is it dominant or recessive? Human Genetics 38. 39. 40. 41. 42. 43. 44. 45. 46. 47. 48. 49. 50. 51. What is a pedigree? What does a circle represent? What does a square represent? Name 2 Human traits that follow Mendel’s Genetics How do pedigrees help us? Are most diseases recessive or dominant? Why? What is the physical basis of cystic fibrosis? what ethnic group is most at risk? What amino-acid is missing in the cell membranes?What chromosome is the main gene on for this disease? What is the physical basis of Taysach’s disease? What ethnic group is most at risk? What is the physical basis of Sickle cell anemia? What ethnic group is most at risk? What is pleiotropic? What type of inheritance does sickle cell follow? What is thought to be the selective advantage of the Heterozygote sickle cell? What is malaria? What is Huntington’s chorea? Where is the gene found? What is the physical basis of the disease? Why do all cultures have a taboo against marrying relatives?
