right or wrong questions : evolution

please answer the next questions in right or wrong  :
When humuzigottym advantage over Ahtrozigottym:
1. Common result is the common allele (frequency 50%) control the population.
On
2? Genetic variation will fade away.
When otrozigottym advantage over Ahhumuzigottym:
3. Selective advantage without damaging in the htrozigott has exactly the balance that has in the humuzigott disadvantage.
4 Locus genetic variation is maintained despite the action of selection against one of alleles.
5. Allele of an humuzigott against which operates more robust selection of the population will disappear first.
And.
6 Created a stable polymorphism and incidence of different alleles in equilibrium will be equal (p = q = 0.5).
7. Allele effect on fitness depends on the second allele with whom he appears in particular.
VIII.
8. Two alleles found after a different frequency than expected population balance - Weight Hardy - Weinberg.
