Natural Selection,Gene Flow,Genetic Drift

A virus killed most of the seals in the North Sea (e.g. dropped the population from    8000 to 800).  In an effort to help preserve the species, scientists caught 20 of the   remaining seals and used them to start a new population in the northwest Pacific   Ocean.  Which of the following statements would accurately describe the new   population?  

• The new seal population is genetically less diverse than the original population 
• The new seal population is genetically more diverse than the original population
• There is equal genetic variety compared  to the original population 
• None of the answers
