What is the practical consequence of the Westiepoo being an F1 cross regarding its genetic makeup?

Answer

Its genetic makeup is inherently variable, leading to unpredictable outcomes in appearance and temperament among littermates.

As an F1 cross, the Westiepoo inherits a 50% genetic contribution from the Westie and 50% from the Poodle. This exact combination results in significant genetic variability within a single litter, meaning appearance and temperament traits are often unpredictable, leading to a 'genetic lottery.' This lack of uniformity is a direct consequence of the hybrid designation and is why these crosses are not given formal scientific classifications; breeders attempting stabilization must pursue multigenerational crosses over many generations.
