To the left are two images of natural hybridization in rattlesnakes (Western Diamond-backed
Rattlesnake (C. atrox) x Timber Rattlesnake (C. horridus)) from Texas. It is extremely rare
between these two species and only three individuals have ever been recorded to this date.
Identify which isolation mechanisms are not active when this type of event occurs and the
potential microevolutionary mechanism that could weaken reinforcement between the two
species. (hint: There can be more than one answer for this question) Mechanical isolation;
mutation behavioral isolation; gene flow temporal isolation; mutation gametic isolation: gene
flow \& mutation.
