Can you breed a box turtle with a red ear slider turtle?

Answer 1

Box Turtles are land turtles and mate on land and Sliders are water turtles and mate in the water, so this would never happen and if it did, they would not be able "procreate" (have young). A Red Eared Slider can only procreate with another Red Eared Slider but they have been known to "mate" (have sex) with Yellow Bellied Sliders. They probably wouldn't try to mate with any other kind of turtle, other than a similar species of water turtle like a Painted Turtle or maybe a Map Turtle. A Slider probably would not try to mate with a Soft Shell Turtle or a Snapping Turtle even though they live in the same water or any species of land turtle like a Box Turtle because they would not recognize it as a possible mate. When a Red Eared Slider tries to mate with a Yellow Bellied Slider, it is because its instincts are telling it that based on size, shape, and mating displays and behaviors, etc., it is another Red Eared Turtle. Interestingly, Red Eared Sliders and Yellow Bellied Sliders rages currently overlap and where they do there is a lot of unsuccessful mating going on between the two species but they cannot procreate. That is part of the "definition" of a separate species. There are very few species of land turtles in the Eastern Box turtle's Range that it could mistake for another Box Turtle and try to mate with. For much of its range the only other land turtle around would be the Wood Turtle (AKA: Red Legged Turtle) and they are not very similar.
