If D and R represent two linked molecular marker loci, where D is a locus with a simple DNA sequence difference, and R is a locus showing variable numbers of tandem repeats, what will the recombinants for this cross be? D1 R1/D2 R2 \times D3 R3/D3 R3 D1 R2/D3 R3 and D2 R1/D3 R3 D1 R1/D2 R3 and D3 R3/D3 R3 D2 R1/D1 R3 and D3 R3/D3 R3 D1 R2/D2 R1 and D3 R3/D3 R3
