an allele starts with a frequency of 0.2 in a population. what is the probability that this allele will go to fixation?
Homework Answers
The probability that this allele will go to fixation is 0.2 or 20%.This is as suggested by genetist Sewall Wright in 1931.According to him, the probability of allele fixation is equal to the starting frequency of the allele.In this case , the starting frequency of allele is 0.2.So, the probability of allele fixation is 0.2 .

An allele, A1, in a diploid population of size N, starts at an allele frequency of 0.7. What is the expected allele frequency in the next generation? In the 100thgeneration? What is the probability that the allele frequency will increase in the next generation? If you follow 100 populations that start with the same conditions for millions of generations, how many would you expect to be fixed for A1?

9. In another population the frequency of individuals with each genotype is MM = 0.25, MN=0.45, NN=0.30. a. Given the following relative fitness values for each genotype, calculate the total population fitness: WMM-1, WMN=0.9, WNN=0.8. b.

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):...
