Solution

The correct option is B 10
The total number of linkage groups in an organism equals to the number of autosomes in its haploid cell. Maize has ten pairs of chromosomes, which means that the number of autosomes in its haploid cell is 10. Hence, total number of linkage groups will be 10, provided all the genes are mapped. Correct answer is B.
