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 1 generation. • Reset bag with 100 chips with these color frequencies and REPEAT until you have collected data for 2 more generations. Spread sheet by Corey Zapin & Kyra Ducoat

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 1 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?

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)

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 2 more generations. What real life genetic disorder could this represent?
