The `mark_prop()` function can be used to filter markers depending on the proportion of each genotype. Here, we have a F2 so we can use the "homo" argument in order to filter depending on the proportion of both homozygous genotype. If we have a N2, we can filter with the proportion of homozygous individuals with the "homo" argument and of heterozygous individuals with the hetero" argument. Moreover, this function allows to filter marker depending on the proportion on non genotyped animals. By defaults, markers for which more than 50% of individuals were not genotyped.
