To chock whether a fly has the mutation, a DNA sequence is analyzed in a way that kills the fly, so the biologist only wants to test a sample of the flies to estimate the proportion of flias that have the mutation. The biologist solocts 40 flies to scquence at random and finds that 9 of them have the genetic mutation.
