Figure 5.

Recombination between different chromosome 10 variants. Chromosomes with differing R1 alleles were made heterozygous and then crossed as females to tester lines. Recombination was measured between R1 and a second PCR marker that maps to within the Ab10 haplotype. The inferred locations of the PCR markers are shown relative to the B73 genome assembly (although the markers are dominant to either K10L2 or Ab10 and do not amplify from N10). In the pairing of N10 and Ab10, the genetic distance between R1 and any marker within the haplotype is <2 cM, due to the large inversion that defines the haplotype. Measured recombination values are shown, where n is the number of progeny assayed.
