2. HARDY WEINBERG: CASE STUDIES I
• Count out 50 chips of each color • Determine which will represent the dominant
and which will represent the recessive allele
• Mark this on your data sheet • Determine p and q values and mark your data sheet
• Place chips in the bag
• Choose chips 2 at a time and tally the offspring genotypes chosen
• Replace chips, draw again
• Determine p and q frequencies at the end of generation.
• Reset bag with 100 chips with these color frequencies and REPEAT until you have collected data for 2 more generations.

3. HARDY WEINBERG: CASE STUDIES II
• Count out 50 chips of each color • Determine p and q values and mark your data sheet
• Place chips in the bag. Choose chips 2 at a time. • Make tallies on your data sheet • DRAW A LINE THROUGH THE aa column and MARK THESE AS DECEASED! (Don’t count in tally!)
• Determine p and q frequencies at the end of generation.
• Reset bag with 100 chips with these color frequencies and REPEAT until you have collected data for 2 more generations.
What real life genetic disorder could this represent?

4. HARDY WEINBERG: CASE STUDIES III
• Count out 50 chips of each color • Determine which will represent the dominant
and which will represent the recessive allele
• Mark this on your data sheet • Determine p and q values and mark your data sheet
• Place chips in the bag. Choose chips 2 at a time Tally results •Determining alleles- If combination is: “Aa” - tally on your data sheet
“aa” Cross off this column (Don’t count these)
“AA” – flip a coin HEADS they survive (count these) TAILS go die (don’t count these)

5. HARDY WEINBERG: CASE STUDIES III
• Determine p and q frequencies at the end of generation 1.
• Reset bag with 100 chips with this color frequency and REPEAT until you have collected data for more generations.
What real life genetic disorder could this represent?
