Simulation of genetic control. Homozygous-viable pericentric inversions in field-female killing systems
1991
Foster, G.G.
The GENCON simulation program GC5 is designed to simulate genetic population control using field-female killing (FK) systems carying pericentric inversions in addition to Y-linked translocations and deleterious mutations. Homozygous-viable pericentric inversions are included on the same chromosomes as the deleterious mutations, in repulsion to the Y-linked translocation. Released males transmit the inversions and mutations to their daughters and the translocation to their sons. Daughters are semisterile regardless of the type of male they mate with, because products of crossing-over within the inversions carry inviable duplications and deficiencies. Compared to present FK systems, inversion-containing strains give higher levels of genetic death, with both faster initial suppression and greater persistence of genetic death from field-reared descendants if releases are interrupted. At low release rates, both types of FK system are more effective than sterile males.
