Frequency of drive carriers in cage populations. Flies carrying 1 copy of the drive allele and two copies of Cas9 were introduced at initial frequencies of 8.8% (cage 1) and 41.3% (cage 2) into a population that was wild-type at the drive site and homozygous for the Cas9 allele. The cage populations were followed for several nonoverlapping generations, each lasting 12 days, including 1 day of egg laying. All individuals from each generation were phenotyped for DsRed, with positive drive carriers having either 1 or 2 drive alleles (all drive carriers in the initial generation were drive/wild-type heterozygotes).
