$10.$ If the researcher found a gene for Jollyness that happened to map in

between B and R$,$ what would happen to the map?

A$.$ This would only decrease the B to R distance

B$.$ This would only increase the B to R distance

C$.$ This would increase the B to R and G to R distance but not B to G

D$.$ This would increase the B to R$,$ G to R and B to G distances.

E$.$ This would decrease the B to G and G to R distances while increasing the B

to R distance.
