Analysing gametic variation with an animal model.

A method is presented to treat gametes as homozygous diploid individuals allowing their inclusion into the relationship matrix between animals. In this way standard techniques developed for the analysis of individual genetic variation may be used to analyze gametic variation. An example is given for maternal gametic imprinting and equivalence is shown to a gametic model. The method may also be adopted for the analysis of species (like the honey bee) with one haploid sex.
