| Modern Genetic Analysis Chapter 17. Population and Evolutionary Genetics Random Events Figure 17-17. The appearance, loss, and eventual incorporation of new mutations in the life of a population. If random genetic drift does not cause the loss of a new mutation, then it must eventually cause the entire population to become homozygous for the mutation (in the absence of selection). In the figure, 10 mutations have arisen, of which 9 increased slightly in frequency and then died out. Only the fourth mutation eventually spread into the population. (After J. Crow and M.
