Answer 1

if M.U.s means Map unit then this means we have calculate the distance between the all the 3 genes le 6 vg bro creecessive mutant) + + + Child type) we → the categones are: on the basis on ig as central gene because it is the gene which gat displaced in Double Cross over (oo).

if M.U.s means map units then this means we have to calculate the distance between b and vg and vg and bw.

Because we determined that vg is the central gene for other two genes.
