If 2n=20, then there are 10 chromosomes. Linkage groups are groups of genes that are so close together on a chromosome that they tend not to assort independently (i.e. recombination rarely occurs between them). This means that these genes will likely be inherited together. With no knowledge of the distribution of the genes on each of the chromosomes, I don't think it is possible to know how many linkage groups there are based on the chromosome number. However, if you consider each chromosome as a linkage group (which would only be true if there were no recombination), there would be 10 linkage groups in a cell with 10 chromosomes (i.e. 2n=20).
