dek16 and dek23 are tightly linked on chromosome 2L

Among 97 ears from selfs of the cross + + x (+ dek16)/(dek23 +), no ears were found which did not segregate 3:1 for a defective kernel mutant, although it was impossible to distinguish between dek16 and dek23 segregating ears. These data indicate that while these two phenotypically similar mutants are non-allelic, they are very tightly linked.
