The correct answer is:
higher than that of the genes w and m
T. H. Morgan proposed the chromosomal theory of linkage, he experimented on Drosophila melanogaster (Fruitfly). In Cross A he took 2 genes y and w which are about 1.3 map unit distant from each other so he obtained 98.7% parental characters (due to higher linkage) and 1.3% recombinant characters.
In Cross B, he took 2 genes w and m genee which are about 37.2 map unit distant from each other, so he obtained 62.8% parental characters (due to comparatively lesser linkage) and 37.2% recombinant characters.
