Instructions - you will be given a slip of paper indicating whether or not you are a sperm or an egg. This slip of paper will have seven letters on it, each representing one trait that will be passed on to your offspring. They are in this order:

• Gender - you will have an X if you are an egg and an X or Y if you are a sperm.
• Head shape - Either a capital or small A.
• Hair Style - Either a capital or lower case D.
• Hair Color - R,y, or B (red, yellow or blue)
• Eye Color - E or e, Determining whether red, blue or purple
• Ear Shape - T or t, triangle being dominant over circular
• Mouth Shape - F,S, or 0 (frown, smile or nothing)

It is your job (if you are a sperm) to find an egg and combine your genes to determine what your "child" will look like. The two of you would then need to draw a picture of your child. You will be graded on how well you determine the phenotype from the genotype.

• Gender X or Y
  • XY is male
  • XX is female
• Head Shape A or a
  • AA is triangle
  • Aa is square
  • aa is round
• Hair Style - D or d
  • DD, Dd is curly
  • dd is straight
• Hair Color - R y or B
  • RR is red
  • Ry is orange
  • RB is purple
  • yy is yellow
  • yB is green
  • BB is blue
• Eye Color - E or e
  • EE is red
  • Ee is purple
  • ee is blue
• Ear Shape - T or t
  • TT, Tt is triangular
  • tt is circular
• Mouth Shape - FS0
  • FF or F0 - Frowny
  • SS or S0 - Smiley
  • 00 - an O shape
  • FS - A wavy line

Using only these seven "genes," there are 432 possibilities for genotype - 288 possible sperm types and 144 possible egg types.
