Scientific Skills Exercise Using the HardyWeinberg Equation

Scientific Skills Exercise: Using the Hardy-Weinberg Equation to Interpret Data and Make Predictions Number of Seedlings Time Green-yellow Yellow Green (days) (CGCG) (CGC) (CYC) Total 216 49 56 47 106 173 21 20

Solution

In this case,the observed fequency of a genotype in a population is the number of individuals of that genotype divided by the total number of individuals.

So the observed frequency at day 7 for genotype:

C^GC^G =number of individuals of that genotype/ total number of individuals

= 49/216 =0.227

C^GC^Y = 111/216= 0.514

C^YC^Y = 56/216 = 0.259
