  2. $100 The “father of Genetics.” This Austrian Monk prompted the study of heredity.

  3. Who is Gregor Mendel?

  4. $200 This plant was the first subject of a heredity experiment.

  5. What is the Pea Plant?

  6. $300 Mendel discovered that sometimes one of the P1 traits failed to appear in the F1 plants, then reappeared in a ratio of about THIS in the F2 generation.

  7. What is 3:1?

  8. $400 This graphical representation of a family record shows how a trait is inherited over several generations.

  9. What is a pedigree?

  10. $500 These are the four patterns of inheritance that we learned and an example of a trait inherited in each way.

  11. 1. Complete dominance: tongue rolling, widow’s peak, hitchhiker’s thumb, earlobe shape…2. Incomplete dominance: flower petal color, human skin color3. Codominance: human blood type4. Sex-linked: muscular dystrophy, color-blindness, Tay Sachs disease, Hemophilia

  12. $100 This type of trait can control or mask another trait.

  13. What is a dominant trait?

  14. $200 This segment of DNA on a chromosome controls a particular trait.

  15. What is a gene?

  16. $300 This type of trait results when a gene is located on the X or Y chromosome.

  17. What is a sex-linked trait?

  18. $400 A term used to describe the appearance of an organism. For example, curly hair.

  19. What is phenotype?

  20. $500 Occurs when both alleles for a gene are expressed in a heterozygous offspring- not an intermediate between the two.

  21. What is co-dominance?

  22. $100 This simple cross only considers one trait at a time.

  23. What is a monohybrid cross?

  24. $200 The genotype in the hidden square.

  25. What is aa?

  26. $300 If A is dominant for axial flowers and ‘a’ is recessive for terminal flowers, this is the trait expressed in the offspring of the following cross:

  27. What is Axial/dominant?

  28. $400 This is the genotype resulting in offspring from parents who are both homozygous recessive for blue eyes.

  29. What is bb (homozygous recessive)?

  30. $500 This is the % of offspring able to roll their tongue AND have free earlobes when: Mom=Heterozygous for tongue rolling and Homozygous dominant for free earlobes Dad= Homozygous recessive for the inability to roll tongue and heterozygous for free earlobes. (2 ½ minutes)

  31. What is 50%?

  32. $100 This is the percent chance that genotype will be homozygous recessive in the following square:

  33. What is 50%?

  34. $200 This common phenotypic ratio results from a dihybrid cross where both parents are heterozygous for both traits.

  35. What is 9:3:3:1?

  36. $300 This is the genotype of the parents whose offspring results in the following prediction: (45 seconds)

  37. What is Bb / Heterozygous?

  38. $400 This is the phenotypic outcome of the offspring resulting from a mother with AO genotype and father with BB genotype.

  39. What is 50% AB, 50% B?

  40. $500 This is the percent chance that a colorblind female will have a colorblind son.

  41. What is 100%?

  42. $100 This is the chromosome passed on only by the father.

  43. What is the Y Chromosome?

  44. $200 Using the cross below, this is the Genotype of the mother.

  45. What is BbSs?

  46. $300 A blue eyed mother has a brown eyed child and a blue eyed child. This is the phenotype of the father.

  47. What is brown eyed?

  48. $400 A boy has blue eyes and his mother has blue eyes. This is the only genotype that the father could NOT be.

  49. What is Homozygous Dominant (BB)?

  50. $500 This is the percent chance that a colorblind father will pass on his trait to a male offspring.
