The other 50% are parental .If two genes occur on the same chromosome, they may not assort independently at anaphase of meiosis. These genesare said to be linked and demonstrate linkage in genetic crosses. Linkage is present when fewer than 50% of thegametes produced by a double heterozygote are recombinant..2 Genetic Mapping Genes with recombination frequencies less than 50% are present in the same chromosome (linked). Two genesthat undergo independent assortment, indicated by a recombination frequency of 50 percent, are either on non-homologous chromosomes or are located far apart in a single chromosome.
