Fig 5. Example of species introgression in the vector genetics model.

The mean (solid line) and one standard deviation (shaded area) of genomes in the population over time of 50 stochastic realizations when 10000 male and female mosquitoes of species 2 that are homozygous in ‘b0’ are introduced into a population containing only species 1 mosquitoes homozygous in ‘a0’ 200 days after simulation starts. (A) When no introgression occurs, and each species has equal habitat to procreate. (B) Hybrid mosquitoes heterozygous in ‘a0’ and ‘b0’ have a 10% lower mortality rate than species 1 or species 2 mosquitoes.
