of count data, for example testing brood survival data in crosses between taxa.

3) Programs to demonstrate natural selection and
genetic drift.
NATSEL.EXE
and DRIFT.EXE (16-bit DOS), written by Jim Mallet.
4) Program to calculate linkage disequilibria
for loci of arbitrary dominance.
DIS.EXE (16-bit
DOS), written by Jim Mallet.
Dominant, recessive, and codominant
loci are allowed (e.g. in colour-pattern loci, AFLP loci, RAPDs etc.). Cytonuclear disequilibria can
also be estimated (e.g. mtDNA haplotype vs. allozyme loci). For dominant genes, estimates assume Hardy-Weinberg
at each locus. Only two alleles per locus are allowed, so this program is mainly
useful for hybrid zone studies or studies of natural hybridization. It would be useful for SNPs but not for microsatellites which have many more than two alleles. The program uses a likelihood-based method
equivalent to that in Hill WG (1974) Heredity 33: 229-239. See also: Dasmahapatra, K.K., Blum, M.J., Aiello, A., Hackwell,
S., Davies, N., Bermingham, E.P. & Mallet, J. (2002). Inferences from a

5) Program to randomize mimicry associations
among hostplants.
RANDMIM.EXE (32-bit
WINDOWS). Specially written for Keith Willmott, and extremely
specialized; not likely to be useful for anyone else! More details on
the "Explanations" worksheet of HOSTMIM.XLS supplied in the package. See: Willmott, K.R.
& Mallet, J. (2004). Correlations between adult mimicry and larval
hostplants in ithomiine butterflies. Proceedings of the Royal Society
of London, Series B 271 (Biology Letters S5): S266-S269. REPRINT
6) Program to test for recombination in a DNA sequence or haplotype, by testing for evidence for a correlation between linkage disequilibrium and distance along a sequence.
RecombiTEST by Gwenael Piganeau (online test). Tests are separately done with two standardized measures of disequilibrium (R2, and with D/Dmax , or D', and measure the decline in correlation of the disequilibrium measure with distance along a sequence in a sample of aligned haplotypes. The correlation coefficient is bootstrapped 1000 times to test for significance. Programme automatically deletes from the alignment gaps and sites with more than two bases (This is not from our lab, but I couldn't find the website via an internet search, so I have put the link online partly for our own convenience. As used in: Piganeau, G., & Eyre-Walker. A. 2004. A reanalysis of the indirect evidence for recombination in human mitochondrial DNA. Heredity 92:282-288.)
