The objective of this work was to obtain the estimates of recombination frequency, through simulation, for different situations in genetic mapping involving full sibling families. A genome with three linkage groups simulated, each one with 11 molecular marks which were multi-allelic, codominants, with saturation of 10 cM. Starting from this genome, two situations were simulated: one with informative genitors, and other with genitors formed randomly. Once all the recombination frequencies were estimated, it was found out that in completely informative loci, the recombination frequency can be calculated among equal pairs of loci starting from the gametic frequency of each genitor, or starting from the genotipic frequency of the progeny. For partially informative loci, the recombination frequency starting from the united genotipic frequency is more appropriate.
