Estimate the frequency of the band allele for a set of RAPD markers.
freq(dat)
dat |
A matrix of size (n.ind x n.mar) containing RAPD phenotypes, with 1 indicating the presence of a band and 0 indicating absence. |
The RAPDs are assumed to be in Hardy-Weinberg equilibrium, and so the
frequency of the band allele is estimated as \hat{p} =
1-\sqrt{1-\bar{x}}
where
\bar{x}
is the proportion of individuals showing a band.
A vector of length n.mar, containing the estimated frequencies of the band allele for each RAPD marker.
