Estimation of Mating Cycle Components of Selection in Plants

摘要: At any instant the gene pool of a population is expressed as an array genotypes and one main goals evolutionary genetics to determine how genotypic frequency distributions populations are transformed over generations. In considering factors that cause in change sense it convenient identify two components selection, acting distinct parts life cycle. The first viability. Viability selection concerned with changes which occur within generation, n, thus reflects probability survival from fertilization reproductive maturity. To estimate net viability we have know composition at time reproduction. It also informative various intermediate stages, e.g. infancy, childhood, youth, because may not operate same intensity, or even direction, different stages
