Summary
Intercross families in which at least three alleles are segregating at each of a pair of linked loci can be used to obtain simultaneous and independent estimates of both male and female recombination frequency. When only two alleles are segregating at one locus, it is still possible to estimate the frequency of recombination both on the male and the female side of the cross, but such estimates are no longer independent.
Numerical examples of each type of intercross family are given and the efficiencies of these families are compared both inter se and with those of the more familiar type of family in which only two alleles are segregating at each locus.
The circumstances in which it is worth obtaining such intercross families are discussed.
