Inbreeding disrupts the Hardy-Weinberg, but it does not, at least in theory, change allele frequencies. True b. False 32. Applying the biological species concept to this situation, one would conclude that lions and tigers are, in fact, the same species. True b. False 34. Hawaiian c. Galapagos d.
Drift is most important in small populations.
Drift tends to maintain or even increase genetic variation within individual populations. Drift operating in a series of populations will cause them to diverge. The direction and magnitude of changes due to drift cannot be accurately predicted. All of the above are true about genetic drift. Five breeding pairs of rabbits are introduced from the U.S. onto an isolated island in the Pacific Ocean.
