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.

Case B: In this population, the frequency of the dominant allele, B, is 0.5 and the frequency of the recessive allele, b, is 0.5. However, in this situation any individual who is born with the dominant trait has a 50 % chance of not surviving to reproductive age. Assuming that mating is still random, what will happen to the allele frequencies (p and q) after 5 generations? (le. Will one allele increase or decrease?) Prediction (1 mark): Reason (2 marks):...

1. Natural Selection happens to a population, Does NOT happen to an individual. What is the difference between a population and an individual? What happens to populations with little or no variation of genetic traits? 2. Which bean variety had an advantage? (what is your evidence?) 3. What characteristic (s) were advantageous? 4. Who or what did the selecting of the advantageous trait? 5. Did any bean variety have a disadvantage? (evidence?) 6. What changes might you expect to see...
what do you think will happen to the variety of colours as the allele frequency of...
what do you think will happen to the variety of colours as the allele frequency of the dominant allele at each of the ambiguous loci increases? We will begin to see fewer individuals with the homozygous recessive genotypes and therefore the variety of colours will decrease. We will the same number of individuals with the homozygous recessive genotypes and therefore the variety of colours will remain the same. We will begin to see more individuals with the homozygous recessive genotypes...

How you think the allele frequencies are being affected by genetic drift in our simulation. Do you think this is speeding up or slowing down the rate of allele change? Why? Plot a graph of the H (p) allele frequency over generational time (show a minimum of three generations) showing what you would expect to happen if both natural selection and genetic drift are happening. Make sure to explain why you think this pattern would occur
