Abstract A finite diploid population, observed at times t = 0, 1, 2,…, is studied. An individual is said to be in age group i at time t if its age is between i and i + 1 units at that time, where i ⩾… (More)

Abstract We consider a finite dioecious random mating population that is observed at times 0,1,… Let there be age groups 0,1,…, K 1 among males and age groups 0,1,…, K 2 among females, so that the… (More)

SummaryCytoplasmic genes of crop species exhibit non-Mendelian inheritance and affect quantitative traits such as biomass and grain yield. Photosynthesis and respiration are physiological processes… (More)

A problem of interest to many population geneticists is the process of change in a gene frequency. A popular model used to describe the change in a gene frequency involves the assumption that the… (More)

Let us assume that there is a monoecious random mating population that changes cyclically in size. Then, the probability that a nonrecessive favorable mutant is ultimately fixed, if it is originally… (More)

A population with two alleles at one locus is considered. It is assumed that there is random mating of adults and that matings in which a particular pair of genotypes is involved may have a different… (More)

Abstract The theory of heterosis is expressed by simple genetic models. Relevant population means are deduced for differences in gene frequencies among populations. Heterosis for the one-locus,… (More)

Consider a monoecious diploid population with nonoverlapping generations, whose size varies with time according to an irreducible, aperiodic Markov chain with states x 1 N ,…, x K N , where K ≪ N .… (More)

We consider a dioecious population having numbers of males and females that vary over time in cycles of length k. It is shown that if k is small in comparison with the numbers of males and females in… (More)
