Estimation of self-fertilization rate and allelic frequencies in diploidized tetraploids

A methodology for the estimation of the self-fertilization rate and allelic frequencies in diploidized tetraploids is developed. Data from both a population survey and independent progeny arrays from homozygous parents are generally necessary for maximum likelihood estimates. If progeny arrays from a random population sample are examined, then data from the resulting six phenotypic categories may be used. An example using the first approach is given using data from the Menzies’ wallflower, an endangered species in California.
