Answer #1

8. If an allele gives a survival advantage, its frequency will increase over time. This is because of phenomenon like natural selection. THe dominant allele or the allele which is giving survival advantage will be passed over to generations with offsprings and its frequency will always increase. This can also be considered for survival of fittest.

9. If an allele gives a survival disadvantage, its frequency will decrease with time. The reason will be the same that because of natural selection and survival disadvantage the frequency of this allel will decrease because the growing generations are always the improved ones and this will be eliminated slowly. this might not get eliminated completely 100% but the frequency will be very less.
