Northern elephant seal had been reduced to about 20 in 1800s. Biologists studied variation in protein within surviving individuals. They found no genetic differences in the protein among individuals. This lack of variation is due to :
  • a)
    Genetic drift
  • b)
    Population bottleneck
  • c)
    Natural selection resulting in a single best genotype
  • d)
    A very low rate of mutation
Correct answer is option 'A,D'. Can you explain this answer?
