A mathematical model used to determine if a population is in
     A mathematical model used to determine if a population is in equilibrium for a particular trait or if it is being affected by microevolution is called  the Hardy-Weinberg model.  heritability.  the pleiotropic equilibrium model.  the Ellis-Van Creveld diversity model.  Tay Sachs is a disease that is carried as a recessive, T represents the dominant allele and t represents the recessive allele. A child born with Tay Sachs disease would have which genotype for the Tay Sachs trait?  tt.  TT or Tt.  dominant.  t.  Evolution refers to change in  populations of organisms over a single generation.  populations of organisms over many generations.  cultural but not biological adaptations.  genetic and phenotypic changes that take place over the lifetime of an individual. 
  
  Solution
Answer a.If population is not evolving the frequency of allele in a population will be stable.This is applicable only when there is no. Mutation, no selection, no random mating
Answer 2.Tay Sachs disease in this child will inherit what parent will transfer whether it is dominating gene or recessive
Answer b.Evolution take place after many generation changes
