Migrate estimates population parameters (effective
population size and migration rates) using genetic data (electrophoretic
markers, microsatellite markers, sequence data). Migrate is a subset
of LAMARC.
The current version of Migrate uses a simple two population model
with four parameters.

PollenGF uses paternity exclusion
techniques to estimate apparent gene flow using progeny arrays from maternal
plants. Gene flow can be calculated for individual mothers or local
population. Sample data and output are included.

Platform: Macintosh
by John Nason, University of Iowa.
FijAnal is a program to conduct spatial analysis
of kinship or coancestry. " In order to obtain a more powerful test
for fine-scale, spatial genetic structure, genetic correlations between
individuals can be summarized over a range of distance intervals in terms
of a multilocus estimate of kinship (Barbujani 1987) or coancestry (Cockerham
1969). In contrast to Moran's I, genetic structure statistics, such as
the kinship coefficient, have a well developed foundation in population
genetics theory and provide a natural means of combining data over alleles
at a locus and over loci (Heywood 1991). Further, a spatial autocorelation
approach permits the investigation of genetic structure at much finer distance
intervals than estimators of genetic differentiation, such as Wright's
Fst that quantify gene frequency variation among quadrats rather than individuals."

Platform: Macintosh
by John Nason, University of Iowa.
"In the program BS_fij, tests of significance
are performed by using randomization procedures to generate populations
under the null hypothesis of no spatial genetic structure, Ho: fij=0 (see
Slatkin and Arter [1991] for a general discussion of this approach). In
this procedure, map locations occupied by the individuals in the population,
or the subset of the population under examination, are randomly assigned
intact multilocus genotypes drawn at random with replacement from the sample
population. " This program must be run with analyses from FijAnal.

This
collection of programs carry out the following functions:
i) Calculates Rho, an unbiased estimator
of Slatkin's (1995; Genetics 139: 457-462) Rst. Estimates are provided
for both individual loci and over all loci, calculated across total populations
and for all pairwise population comparisons.
ii) Determines if overall Rho values
across loci are significantly different from zero by permutation tests
and uses bootstrapping to provide 95% confidence intervals, mean bootstrap
Rho, plus the variance and SE of
the bootstrap mean Rho.
iii) Calculates Goldstein et als

"The computer program, NEIGHBOR, was written
so that mating system parameters in the neighborhood model (Adams and Birkes,
1991) can be estimated for conifer populations. Application of the model
requires observations on multi-locus genetic markers in the haploid pollen
gametes of offspring from individual mother trees of known genotype. The
model assumes that pollen successful in fertilizing viable offspring is
derived from three sources: self-fertilization, cross-fertilization with
nearby males in an arbitrary defined neighborhood, and cross-fertilization
with males from outside the neighborhood (gene flow). Besides accounting
for levels of self-fertilization and background pollination (mating with
distant males), the model is useful for investigating relationships between
mating success of males within neighborhoods and factors expected to influence
male-mating success; including distance to mother trees, relative fecundity
of males, flowering phenology synchronization (see below), and interaction
between these factors." The set of programs includes a manual
with complete description.

"immanc.c is a program designed to test whether or not
an individual is an immigrant or is of recent immigrant ancestry.
This test is described in detail in the following article: Rannala, B and
Mountain, J.L. (1997) Detecting immigration by using multilocus genotypes.
Proc. Natl Acad Sci, USA 94:9197-9201. In order to apply the test,
one must have genotype data for multiple loci for multiple individuals
of two or more populations (see section on input file below). Ideally,
but not necessarily, all individuals have been tested for all polymorphisms.
The method is appropriate for use with allozyme, microsatellite, or restriction
fragment length data."

"Arlequin is an exploratory population genetics software environment able to handle large samples of molecular data (RFLPs, DNA sequences, microsatellites), while retaining the capacity of analyzing conventional genetic data (standard multi-locus data or mere allele frequency data). A variety of population genetics methods have been implemented either at the intra-population or at the inter-population level, and they can be conveniently selected and parameterized through a graphical interface. Arlequin has no equivalent in his field and will be extremely useful to analyzed the large data sets which are now available by the use of the latest molecular engineering techniques."
"Arlequin's WWW site was officially opened on June 15th, 1996. It is hosted by the Department of
Anthropology & Ecology of the University of Geneva. Arlequin's beta testing period ended on January 31st, 1997 at midnight - time at which version "1-point-oh-no" was released to the scientific community of planet earth!! December 17th, 1997, less than a year later, version 1.1, a significant update, was uploaded to to its web site. The same week, Arlequin's Official User Manual was released in Adobe Acrobat Format."

Bottleneck is a program for detecting recent effective population size
reductions from allele
data frequencies.
"The program BOTTLENECK computes for each population sample and for
each locus the distribution of the heterozygosity expected from the observed
number of alleles (k), given the sample size (n) under the assumption of
mutation-drift equilibrium. This distribution is obtained through simulating
the coalescentprocess of n genes under two possible mutation models, the
IAM and the SMM. This enables the computation of the average (Hexp) which
is compared to the observed heterozygosity (Hobs, in the sense of Nei's
gene diversity) to establish whether there is an heterozygosity excess
or deficit at this locus. In addition, the standard deviation (SD) of the
mutation-drift equilibrium distribution of the heterozygosity is used to
compute the standardized difference for each locus ((Hobs-Hexp)/SD). The
distribution obtained through simulation enables also the computation of
a P-value for the observed heterozygosity."
GDA (Genetic Data Analysis) is a Microsoft Windows program for analyzing discrete genetic data. Both 16-bit versions (for Windows 3.1x) and 32-bit versions (for Windows 95 or Windows NT) are available. The NEXUS data file standard used by the phylogenetic analysis programs PAUP and MacClade has been extended (by the addition of the GDADATA block) to accommodate discrete genetic data. Data can be imported also in: a) BIOSYS format (types 1 or 2); b) Weir format, i.e., the format used used in the 1st edition of the book (see below); or c) GeneStrut format.
DISCLAIMER: GDA is designed to accompany the second edition of Bruce Weir's book "Genetic Data Analysis" (1996. Sinauer Associates, Inc. Publishers, Sunderland, Massachusetts). The program was written independently of the book, and the authors of the computer program receive no royalties from sales of the book. The program GDA is thus offered simply as a service to the scientific community, and access to GDA is not included in the purchase price of the book "Genetic Data Analysis." Although the program GDA is, at present, being distributed freely, the authors reserve the right to seek compensation for future versions of the product. Note that the program is still in the development stage, meaning that new features are still being added and bugs are still being found on a regular basis.This product is offered on a use-at-your-own-risk basis: the authors assume no liability for loss or damage of any kind resulting from your use of this product.
The software and documentation for this program can be downloaded from their website at
