The following options are all reproductive barriers. which one is an example of a prezygotic barrier in which the two different species do mate? view available hint(s) the following options are all reproductive barriers. which one is an example of a prezygotic barrier in which the two different species do mate? two dragonfly species regularly mate, but their gametes are incompatible. one bird species lives in wetlands, the other in dry forests; hence, they do not encounter each other. hybrid mules produced by mating donkeys and horses are sterile. two crayfish species cannot interbreed because their genitalia do not engage properly with each other.

The correct option is this: TWO DRAGONFLY SPECIES REGULARLY MATE BUT THEIR GAMETES ARE INCOMPATIBLE.

In biology, there are different types of reproductive barriers, one of these is prezygotic barrier. A prezygotic barrier is a kind of mechanism that prevent reproduction from occurring by blocking fertilization. In this case, the concerned species will be mating together, but their gametes will not be compatible and thus, zygote will not be formed.

A postzygotic barrier on the other hand is said to occur when the reproduction process is blocked after the formation of zygote or after fertilization has taken place. A good example of this is an hybrid mule that is sterile and can not reproduce.  

i do not know and i have a 100 in this class

i wish i could with all of them i can barley see the first one so here's the answer to the first one b
