If 98 out of 200 individuals in a population express the recessive phenotype, what percent of the population would you predict would be homozygous recessive? [HINT: I have given you information on the frequency of the homozygous recessive (or q2). So start by determining q2 and then solving for q.]

What is the frequency of the homozygous dominants? [HINT: Remember there are only two alleles in the population, so if you add the frequency of the two alleles, it must equal 1. So p + q = 1.]

What is the frequency of the heterozygotes? [HINT: If you know p and q, you can use the H-W equation to figure out 2pq.].

Your original population of 200 was hit by a tidal wave and 100 organisms were wiped out, leaving 36 homozygous recessive out of the 100 survivors. If we assume that all individuals were equally likely to be wiped out, how did the tidal wave affect the predicted frequencies of the alleles in the population? [NOTE: assume the new population is at equilibrium -- AFTER the event, so you are comparing two populations what are at equilibrium to look for changes in allele frequencies.]

1. What is the frequency of homozygous recessive?
2. What is the predicted frequency of heterozygotes?
3. What is the predicted frequency of homozygous dominant?
4. What do we call the phenomenon that caused this change in the population?
