What happens if a flying squirrel mates with regular squirrel?

Flying squirrels and regular squirrels are different species. While they share a common ancestor, they have evolved differently over time and are unable to interbreed. This is due to a number of factors, including:

* Differences in genetics: Their DNA is significantly different, preventing successful fertilization.

* Physical incompatibilities: Their reproductive organs are not compatible, making physical mating impossible.

* Behavioral differences: Flying squirrels are nocturnal and arboreal, while regular squirrels are diurnal and live primarily on the ground. These differences make mating unlikely even if they were physically compatible.

Therefore, a flying squirrel cannot mate with a regular squirrel. They are separate species with distinct evolutionary paths.
