To be able solve this problem, it will be helpful to go and review the two - point mapping data generated for all the three genes that were involved. Putting in to considering that the map distances between jv-h (7.3 mu) and h-th (16.7 mu) equal the sum of the distance between jv-th (24 mu), having been given the distance between th-rai is greater (26.2 mu), the jv gene is said to be located between rai and and h.
