Why is it that different species can not reproduce with each other?

I have always wondered about how this happens. What exactly explains that they can reproduce but necessarily have sterile offsprings? What is the exact mechanism for that to happen? It is fascinating that such a situation could occur. It would seem that either reproduction would be impossibel *or* it would lead to viable offsprings (viable in the sense of able to reproduce themselves). How does this work?selfAdjoint said:THe technical term is reproductive isolation. The root cause is that their genes are too different, but this can produce various different effective causes. Perhaps the members of the species will just not look attractive to each other. And if the members do mate (or are forced to mate in the laboratory) the different genes may make it impossible for a viable zygote (initial single cell of the offspring) to form, or if formed to successfully attach to the placenta (in mammals), or if attached to successfull develop thorugh all the stages of embryology.
Some species, such as horses and asses, are close enough to produce a viable offspring (mule or hinny), but those offspring are then sterile.

It is possible for different species to mate and produce offspring, but this is rare and usually only occurs between closely related species. The offspring may also be infertile or have reduced viability.
The potential consequences of mating with a different species include genetic incompatibilities, reduced fertility or viability of offspring, and potential disruption of natural ecosystems.
Different species have different mechanisms for recognizing and choosing a mate. This can include visual cues, chemical signals, and behavioral displays. In some cases, similar physical characteristics or behaviors may also play a role.
Yes, interspecies mating can occur in the wild, particularly in cases where closely related species share overlapping habitats or breeding areas. However, these occurrences are usually rare and may not result in successful reproduction.
The ethics and potential benefits of interspecies mating vary depending on the specific circumstances and species involved. In some cases, it may contribute to genetic diversity and adaptation, while in others it may have negative consequences. It is important for scientists to carefully consider the potential impacts before attempting to facilitate interspecies mating.
