Solution:

The number of linkage groups present in an individual corresponds to number of chromosomes in its one genome (all the chromosomes if haploid or homologous pairs if diploid). It is known as principle of limitation of linkage groups. Maize has 10 linkage groups, as it has 10 pairs of chromosomes.
