Can linkage maps produced from recombination frequencies between mutant loci be integrated with maps produced by restriction enzyme analysis?
What will be an ideal response?
Ans: Yes. The two maps would be colinear but there may be variation in the probability of crossing over across the chromosome so that the map estimated from recombination frequencies is not as accurate as maps made by ordering restriction fragments.

Managers of power-line rights-of-way in the northeastern United States have discovered that dense shrub thickets, once established, can prevent establishment of forest trees. By maintaining shrubs under power lines, managers can greatly reduce the maintenance expenses (for mowing or herbicide application) normally associated with prevention of tree growth beneath power lines. Of which mechanism of succession are these managers taking advantage?
A) facilitation B) inhibition C) tolerance D) none of the above
