I have several samples with distinct heterozygous ambiguities at particular loci that seem to correspond to the two genotypes of the parents. I want to know if there is a way (e.g., a program, or a utility I don't know about in a common (freeware, preferably Mac platform) program like MEGA or Geneious) to automate and maybe even give a statistic for the likelihood that each sequence is derived from a set of homozygous parents differing at the loci under question? I even have quite a range of parental genotypes against which such a statistic could be pulled. Just trying to avoid a time-sucking and hand-wavy "were determined visually" scenario. Thanks!
