You perform a backcrossing experiment to map regions of the corn genome that responsible for kernel size. first, you cross true breeding plants with large kernels to true breeding plants with small kernels. the f1 hybrids have medium size kernels. you then backcross the f1 to the parents with small kernels, and you genotype the backcross progeny at 100 marker loci. you observe that progeny that are heterozygous at locus 1 have larger kernels than individuals that are homozygous at locus 1. in contrast, individuals that are heterozygous at locus 2 have the same size kernels as individuals that are homozygous at locus 2. which of the following statements is most consistent with your results? a) both loci 1 and 2 are in linkage disequilibrium with genes that affects kernel size. b) neither locus 1 or 2 is in linkage disequilibrium with a gene that affects kernel size. c) locus 2 is in linkage disequilibrium with a gene that affects kernel size. d) locus 1 is in linkage disequilibrium with a gene that affects kernel size.
