Sex-linked genes in age-structured populations


Play all audios:

SUMMARY We study the progress towards equilibrium of the frequencies of sex-linked genes in elementary discrete time models of age-structured, overlapping generation populations. It is found


that, if a finite upper age limit is assumed, the difference in the frequencies of an allele in males and females will oscillate as in the familiar non-overlapping generation models,


although the oscillations may be irregular. Monotonic convergence of that difference, as found by Nagylaki (1975) in continuous-time overlapping generation models without age-structure,


occurs in the models considered here only when there is no upper age limit and when there is “ sufficient “ overlap of generations. SIMILAR CONTENT BEING VIEWED BY OTHERS THE SELECTION FORCE
