Question

There are two populations of mid-western ferret-badgers: one population lives in the Hoosier National Forest in Indiana, the other lives in the Wayne We will be using computer simulations this week in lab. If you wish to bring your own laptop, . download the Populus software from the web site mentioned in this handout and install it. It is a Java-based application that should run on any operating system if you have Java installed Complete the following practice questions: ractice Questions Speciation is thought to occur as a result of different populations accumulating enough genetic differences so that they become unable to reproduce with one another. The evolutionary force called is thought to greatly retard this process. a) gene flow b) genetic drift c) inbreeding d) natural selection e) mutation . Lidicker and McCollum (1997) examined genetic variation in populations of sea otters (Enhydre lutris) in the easten Pacific Ocean. Sea otters were distributed throughout this region before fur hunting nearly led to their local extinction. Along the central California coast only one population of 50 or fewer individuals is thought to have survived; this population was protectedi 1911 and has grown to its current size of approximately 1500 otters. From this information, it is obvious that this population has gone through a , and is likely to have genetic variation. a) migration event; high levels of b) bottleneck; lost some c) mutation: less fit d) founder event: high levels of e) gene pool; Hardy Weinberg

Explanation / Answer

Ans. 1 gene flow is the evolutionary force that retard the process of speciation because gene flow is the process by which genetic material is transferred from one population to another. So if gene flow is there no two population can be isolated. This force retard speciation.
