Can different turtle species be crossed like dog breeds?
For example, Greek tortoise with four-toed tortoise, or German tortoise with leopard tortoise?

My question is how much math is involved in the course and how demanding it is.
Hey. This might be a weird question, but I wanted to know if you think it's weird that I feel guilty about swatting at a mosquito that kept me awake until 1:30 a.m. I really can't kill animals, and even with this mosquito, I made sure it was as quick and painless as possible for…
The intersection of different turtle species is often possible, but absolutely not desired, because most species are threatened in their stock, so you do not need the dangers of art contamination.
In Germany, too, there have already been bastards between the different Testudo species. Mostly this happened because one kept the species together and the males have not found any females of their own kind. However, such blenders do not want to have a responsible holder in his group.
In China there are crooks who deliberately cross different species to sell the descendants as specimens of a newly discovered type for a lot of money. There have even been cross-breeding mixedlings, for example from South American and Asian swamp turtles.
Very interesting, thank you for the answer! 🙂
where the Greeks (Testudo hermanni) and the Moorish land turtle (Testudo graeca) sympathetic, the two species should occasionally hybridize with each other. Whether this is true, however, is not finally clarified because the individuals identified as hybrids are also copies of T. hermanni with undivided supraaudal shield (usually divided in this way) or T. graeca with divided Supracaudale (usually undivided in this way).
In human care, various land turtles have been successfully crossed together. Fritz (2012) calls the following:
Whether the hybrids are fruitful, however, is unknown.
However, hybrid crossings must be rejected in the sense of species protection.

Dog breeds are all the same, the wolf, you can hardly compare it.
Nearly related species are combined into genera. There is often a crossability, although the descendants are not necessarily fertile. Examples would be the genus Equus with horses, donkeys and zebras or the genus Panthera with lion, tiger, leopard, jaguar and snow leopard.
Now the Greek land turtle and the four-tone turtle belong to the same genus Testudo, but a guarantee of crossability is of course not that, there is only a real chance. In doubt, you should try this or find people who tried it.
I didn’t trust the other species. The genres can be found in the Infobox at Wikipedia.
Can one can do a lot, but has no advantages, on the contrary, depending on the combination of species, even diseases and metabolic disorders can be promoted, which in turn promotes suffering and reduces life expectancy. Even in natural habitats there is no intersection, because only a few areas overlap. If the animals meet in the habitat, they do not mate with each other, as at times of juvenile age they only live in small art-pure groups, thereby taking an imprint in their own way. They therefore have no interest in an alien species. In humans, an art mix leads to a misconception that remains the entire life.
Since we have a responsibility for our animals, we want not only to promote health, but also to protect species. It has absolutely no advantages to mix species, but very many disadvantages, especially for animals. A responsible holder therefore ensures that only one (sub) type is held per walk. This also applies if one does not intend to cultivate the breeding (eggs dispose of or equal-sex attitude) because one may overlook a laying and it is wildly brewed and/or misguided for young animals.
I had a case where many years ago there was a vulnerability in the enclosure, so that the neighboring enclosure could mix. I’ve always disposed of all the eggs, but I’ve missed a laying. This slipped turtles that were “other” and all 5 died within a year. Not all mixed animals are consecrated to death, but animal and species protection means preventing such incidents. On the a Concentrate and cultivate this kindly, to serve as a wild man’s ego.

You’ve already given yourself the answer. Dogs of all breeds are always the same species. Crossings in the same way are not a problem. If you cross turtles of the same type, this also works, but crossings between different species only fold in rare cases when the species are very closely related to each other and then their descendants can no longer multiply.
