This page provides links where you can download file archives containing programs for the genetic analyses of half-sib progeny arrays. The programs (entitled "BROOD", "GAMETES", and "HAPLOTYPE") are described in: DeWoody J.A., DeWoody Y.D., Fiumera A., and Avise J.C. (2000) On the number of reproductives contributing to a half-sib progeny array. Genetical Research (Cambridge) 75: 95-105. Click here for a PDF version of this article BROOD estimates the number of progeny that need to be typed in order to detect gametes from all parents that have contributed to a half-sib progeny array. It is particularly applicable to species with large clutch sizes (e.g., amphibians, fish, insects). GAMETES and HAPLOTYPE estimate the number of parents that contributed to a half-sib progeny array. GAMETES uses a single-locus approach, and HAPLOTYPE incorporates data from multiple loci. The "REPRODUCTIVES" package was empirically tested in the following paper: DeWoody, J.A., D. Walker, J.C. Avise. 2000. Genetic parentage in large half-sib clutches: Theoretical estimates and empirical appraisals. Genetics 154:1907-1912.

Difficulties in parentage analysis: The probability an offspring and parent have the same heterozygous genotype. Genetical Research 78:163-170. Click here for a PDF version of this article The archives contain README files that provide documentation for each program. They also contain sample data files and the Matlab code. We are in the process of converting the Matlab code to C, and hope to make the C code and executable versions available soon. Click here to download .zip archive for PCs and UNIX systems. This page also provides access to links which allow an Excel spreadsheet to be downloaded. This spreadsheet calculates three types of parental exclusion probabilities (described in: J.A. DeWoody, A.F. Fiumera, and J.C. Avise. Which parental exclusion probability to include? In revision. Click here to download .zip archive of the Excel spreadsheet for PCs and UNIX systems.
