Detective Pux here, ready to investigate the possibility of crossing a lemon with an orange.

First off, let's establish some facts about citrus fruits. Oranges and lemons are both members of the citrus family, which also includes grapefruits, limes, and tangerines. They share many similarities, such as a thick rind and a juicy interior, but they also have distinct differences, such as their size, color, and flavor.

Now, let's talk about the feasibility of crossing a lemon with an orange. In short, it's not possible. There are several reasons why.

First and foremost, lemons and oranges are different species within the citrus family. They are not closely related enough to be able to crossbreed, similar to a lion and a tiger can't breed to create a liger.

Secondly, even if the genetic makeup of the two fruits were compatible for crossbreeding, it would be very difficult to achieve. The process of crossbreeding plants is a complex and time-consuming process that requires a lot of skill and knowledge. It would be impossible for a person without this skill and knowledge to achieve.

Additionally, even if someone did manage to cross a lemon with an orange, it is unlikely that the result would be a desirable fruit. The resulting fruit would likely have a combination of traits from both the lemon and orange, which may not be desirable.

Finally, it's worth mentioning that there are already some citrus hybrids available in the market like the limequat, which is a cross between a key lime and a kumquat.

In conclusion, while the idea of crossing a lemon with an orange may sound exciting, it's not possible due to the fact that they are different species and even if it was possible the result would be unpredictable and probably not desirable.

This is Detective Pux signing off, always ready to separate fact from fiction and get to the bottom of things.
