Genes situated on the same chromosome that tend to be inherited together are said to be

Explanation

All the genes on one chromosome form a linkage group, and the number of linkage groups in a species equals its haploid chromosome number. Alleles are the alternative forms of one gene occupying the same locus on homologous chromosomes, which is a different relationship altogether. Linkage reduces the proportion of recombinant offspring below the Mendelian expectation.
