Eye color

  1. 1. Eye color
  2. 2. Different colors
  3. 3. Brown
  4. 4. Blue
  5. 5. Grey

  13. 13. Browny-green (Hazel)
  14. 14. Grey with a little brown
  15. 15. Blue – or grey?
  16. 16. Looks grey – is it real?
  17. 17. Obviously NOT real
  18. 18. Who cares, anyway?
  19. 19. How about these guys?
  20. 20. Neanderthal man
  21. 21. What color were their eyes?
  22. 22. Who knows?
  23. 23. Who cares?
  24. 24. How can we find out?
  25. 25. DNA samples?
  26. 26. Remember Jurassic Park?
  27. 27. Fossilized mosquito!!
  28. 28. Take out some blood
  29. 29. Whose blood?
  30. 30. The blood of a neanderthal man!!
  31. 31. Get a DNA sample
  32. 32. Bring back lost people
  33. 33. No … I don’t want to come back!!
  34. 34. I don’t like modern humans
  35. 35. OK … different animals
  36. 36. Bring these back
  37. 37. Great idea
  38. 38. We can do it!
  39. 39. We have the cloning technology
  40. 40. Really?
  41. 41. We really have the cloning technology?
  42. 42. No, not really!
  43. 43. Don’t be stupid.
  44. 44. It’s just a movie!
  45. 45. But scientists CAN analyze DNA
  46. 46. That’s kind of clever
  47. 47. For example?
  48. 48. Get DNA from bones
  49. 49. Figure out eye color
  50. 50. Figure out eye color?
  51. 51. Yes
  52. 52. Not cloning dinosaurs?
  53. 53. No
  54. 54. Who is going to study that?!
  55. 55. Molecular biologists
  56. 56. Exciting!
  57. 57. Eye color and DNA
  58. 58. We can predict eye color!
  59. 59. Kind of …
  60. 60. To a certain extent
  61. 61. Predict eye color?!
  62. 62. Parents’ eyes, children’s eyes
  63. 63. Two brown eyed parents • 75% chance brown • 19% chance blue • 7% chance green
  64. 64. One brown one blue • 50% chance brown • 50% chance blue • 0% chance green
  65. 65. That’s SO exciting!
  66. 66. Who needs this?
  67. 67. We can predict EYE COLOR!!!!
  68. 68. Actually, some people care
  69. 69. Forensic scientists
  70. 70. Computer forensics
  71. 71. Forensic molecular biology
  72. 72. Forensic science
  73. 73. Elementary, my dear Watson
  74. 74. Actually, it’s NOT elementary
  75. 75. It’s very complicated
  76. 76. Analysing DNA to solve crimes
  77. 77. DNA swab test
  78. 78. Maybe you commit a crime
  79. 79. We get a sample of your DNA
  80. 80. You are the criminal
  81. 81. I am Poirot
  82. 82. I don’t need DNA
  83. 83. I am a fictional detective
  84. 84. How do they do it?
  85. 85. Study molecular biology
  86. 86. Chromosome
  87. 87. Long strand of DNA
  88. 88. DNA consists of many genes
  89. 89. Genes carry code
  90. 90. Eye color, blood type, etc
  91. 91. Genes are segments of DNA
  92. 92. Certain genes determine eye color
  93. 93. • Eight genes for eye color • Two are the strongest predictors • But they ALL have an influence
  94. 94. Forensic science
  95. 95. Must be very accurate
  96. 96. Must be VERY careful
  97. 97. Modern forensic scientists …
  98. 98. … use computers
  99. 99. Computer models of genetic variation
  100. 100. NOT like this!
  101. 101. DNA samples
  102. 102. Eye color data
  103. 103. From 6,000 people
  104. 104. Information into the computer
  105. 105. Great!
  106. 106. I’m a forensic molecular biologist
  107. 107. Call me FMB
  108. 108. Give me your DNA sample!
  109. 109. Give it to me!!
  110. 110. OK, here it is!
  111. 111. Here’s my DNA sample
  112. 112. OK, I’ve analyzed your DNA sample
  113. 113. I used my fantastic computer model!
  114. 114. Now I will predict your eye color!!
  115. 115. Using my fantastic computer model!
  116. 116. Why don’t you just look at my eyes?
  117. 117. Shut up!
  118. 118. I will use my great computer model
  119. 119. OK, I’ve finished.
  120. 120. Your eyes are blue
  121. 121. No, they are brown
  122. 122. Never mind. Only 90% accuracy for blue and brown
  123. 123. Why didn’t you just look at my eyes?
  124. 124. Shut up! This is forensic science
  125. 125. 90% accuracy for blue and brown
  126. 126. 70% for other colors
  127. 127. The future is bright
  128. 128. We can predict everything!
  129. 129. Your hair is red!
  130. 130. Your designer baby’s hair will be blue
  131. 131. Wait … designer babies?
  132. 132. Is that a good idea?
  133. 133. Should we be able to decide EVERYTHING?
  134. 134. Even change things about our babies?
  135. 135. Change a baby’s DNA?
  136. 136. Should scientists really be involved in this?
  137. 137. Can we trust scientists?
  138. 138. Is it natural?
  139. 139. What if you gave a DNA sample …
  140. 140. … then three weeks later …
  141. 141. … the police come to your door …
  142. 142. … and say, we compared your DNA …
  143. 143. … with DNA at a murder scene.
  144. 144. You are a murderer!
  145. 145. You are a murderer!
  146. 146. You are a murderer!
  147. 147. My computer model says so!
  148. 148. Now let me make a T Rex
