species concepts
which species concept describes a group of populations whose members have the potential to interbreed in nature and produce viable, fertile offspring?
biological species concept
what is the transfer of genes between two populations called?
gene flow
which mode of speciation requires a land barrier?
allopatric
is a zonkey considered a species?
no
ecological, behavioral, temporal, and mechanical isolation are all examples of (prezygotic/postzygotic) isolation
prezygotic
which species concept does a hybrid animal violate?
biological species concept
what mechanism for evolution involves fitness?
which mode of speciation does not involve a land barrier?
sympatric
what is it called when new species are formed?
speciation
postzygotic
if two organisms are very genetically similar, but can be reliably distinguished by a physical feature, what species concept applies to this situation?
morphological species concept
what type of evolution happens at the population level?
microevolution

what two conditions make up a species?
ability to reproduce and produce fertile offspring
two animals having different mating calls is an example of _____ isolation
behavioral
if two organisms share a common ancestor, what species concept is applied here?
phylogenetic species concept
what is evolution at or above the species level?
macroevolution
which mode of speciation is more common?
allopatric
what is the offspring of two different species called?
hybrid
is the formation of zonkeys due to prezygotic or postzygotic isolation?
postzygotic
if two organisms diverge into populations which breed on different types of fruit, but can interbreed if placed in a lab setting, what species concept is applicable here?
ecological species concept
what can occur if a barrier preventing gene flow is lifted, but gene flow does not resume?
speciation
polyploidy, sexual selection, and habitat differentiation are examples of which mode of speciation?
what is an example (besides the zonkey) of an animal that is not a species?
mule
what isolation mechanism is acting when two animals breed at different times of day/month/year?
temporal isolation
