Hence, an estimation of the recombination frequency
can be made by deducting one half of the total F2 progeny number from the wild-type category and then treating the rest of the data as testcross data.
Abbreviations: GLC, gas-liquid chromatography; NMS, nuclear male sterile/sterility: r, recombination frequency
Variability for recombination frequency
in the AP12 soybean population.
The discussion above of the effect of selecting progeny with high numbers of recombinants differs somewhat from the discussion given in Darvasi and Soller (1995), in that they decreased marker spacing with increases in recombination frequency
due to additional rounds of random mating.
The size difference for this genetic interval is primarily due to a difference in recombination frequency
between Xfcc1 and Xfcg10, which is 2.

Unless otherwise specified, all results presented below were parameterized with the recombination frequency
between the loci r = 0.

The maximum likelihood estimator for recombination frequency
is the value of p that would satisfy the equation below.
The simulations considered changes in the recombination frequency
between a target gene and flanking markers, one to five target genes, different screened population sizes, and the selection of one or two individuals at each selection generation.
On the basis of the three observed recombinant chromosomes (two of which were confirmed by FISH) among 3563 selfed progeny screened, and with the assumption that all progeny were disomic for the critical chromosomes, the recombination frequency
This test indicated that of the overall average recombination frequency

less than 10 cM, most mapping functions have the same behavior in terms of conversion between recombination frequency
and genetic distance; however, when genetic length increases, mapping functions show strong divergences.
Taking into account only the recovered recombinant chromosomes, the overall recombination frequency
of the 1RS arm in the analyzed population was 0.
