1. Other than the fact that the gender ratio 1:4 doesn't exist, you are correct (to a point). The gender may be the same as the test offspring, however it may also change.
Try to think of gender as a number between 1–8, with each gender ratio taking it's shares accordingly. [So for example for a 1:1 Pokémon, 1–4 being Female, 5–8 being Male. But for a 1:7 Pokémon (like starters) 1 is female, 2–8 are male.
But the IVs, nature, ability being passed are all still maintained from the test offspring.
2. I can breed you a hex 0 Pokémon if you're willing to wait a few hours.
