Fig. 5From: A common gene drive language eases regulatory process and eco-evolutionary extensionsPopulation dynamics of CRISPR based homing endonuclease gene drive. A When the fertility rate of heterozygous adults is 0.7 and drive efficiency is 100%, we have \(2 p f_{WD} > f_{WW}\). A small release of WD/DD will invade the population consisting entirely of WW. B When the fertility rate of heterozygous adults is 0.3, we have \(2 p f_{WD} < f_{WW}\). Successful invasion by gene drive would require threshold release of WD/DD in the population. The position of the unstable fixed point is \((WW,DD)=(0.286,0.354)\). Other parameters are fixed to \(f_{WW}=1, f_{DD}=1\) for both A and BBack to article page
