A Population Genetic Model of Evolution of Host-Mate Attraction and Nonhost Repulsion in a Bark Beetle Pityogenes bidentatus
Figure 1
Change in proportions of the nine genotypes during 100 generations (example 1) with indiscriminate mating in which there were initially about 107 (0.9999998 aabb) individuals and initially one mutation of a to A (0.0000001 Aabb) and one of b to B (0.0000001 aaBb) resulting in 0.9994339 AABB after 100 generations. Relative survival of each genotype was S1= 1 (AABB), S2 = 0.8 (AABb), S3 = 0.5 (AAbb), S4 = 0.9 (AaBB), S5 = 0.6 (AaBb), S6 = 0.3 (Aabb), S7 = 0.4 (aaBB), S8 = 0.3 (aaBb), and S9 = 0.2 (aabb).
