Internal genetic structure and outcrossing rate in a natural population of Araucaria angustifolia (Bert.) O. Kuntze

Article Abstract:

An investigation of the internal genetic structure and outcrossing rate of a population of Araucaria angustifolia (Bert.) O. Kuntze was carried out, using sixteen allozyme loci. The analysis of spatial autocorrelation demonstrated the presence of internal structure in the first distance classes up to 70m, suggesting the presence of family structure.

Determinants of effective population size for loci with different modes of inheritance

Article Abstract:

An assessment of the determinants of effective population size in species with overlapping generations is reported. A demographic model is used to investigate the influence of different life-history variables and the influences of sex differences in life-history variables for loci with different modes of inheritance.

Mapping binary trait loci in the [F.sub.2:3] design

Article Abstract:

A new method with a framework of mapping binary trait loci (BTL) set up was implemented via the Expectation-Maximization algorithm which could provide accurate estimates for both the effects and locations of BTL.
