Answer:

<em>What are the allele frequencies in this population?</em>

  • Frequency of S = 0.625  
  • Frequency of s = 0.375

<em>In the next generation of 1000 hamsters, what are the expected genotype frequencies?</em>

  • Frequency (SS) = 0.39          
  • Frequency (Ss) = 0.47          
  • Frequency (ss) = 0.14  

<em>What are the expected number of each genotype in the next 1000 hamsters?</em>

  • Individuals SS =  390
  • Individuals Ss =  469
  • Individuals ss =  140

<em>Have the allele frequencies changed?</em> No, they are the same

<em>Is the population in Hardy-Weinberg equilibrium?</em> Yes, it is.  

<em>The expected genotype frequency of Ss (2pq) in the next generation is expected to be: </em>0.469 (option a)
