Describe how allele frequencies change due to random genetic drift in a small population versus a large population, showing an example of calculating the probability of drift leading to loss of an allele in a small diploid population of size 10, versus a population of size 100.

Expert Solution

Genetic drift is the sudden loss of individuals from a population due to some natural calamity or anthropogenic factor. Because individuals are dead, the alleles present in them will also be lost from the population.

In the given example, we can see that the effect of genetic drift is more prominent in small population. It is because it is giving a change of 0.5 in 10 individuals where as it is giving a change of 0.7 in hundred individuals. So we can say that it is a stronger force in small population.

Please rate high.

Explain why the rate at which allele frequencies change under drift is influenced by the effective population size, yet the neutral substitution rate under drift is uncorrelated with population size.

If genetic drift causes a population to become less diverse, how does it affect the degree of similarity between populations? Can this be thought of as a source of diversity? (will up vote and comment if correct)

Allele frequencies at a wing length locus are measured for a natural population of a migratory cricket species as P(A1) = 0.4 and Q (A2) = 0.6. Observed genotype frequencies in the field population are shown below. Compute the expected frequency of the three genotypes if the population is in Hardy-Weinberg Equilibrium for this locus? Observed frequency Expected frequency Show your work A1A1 = 0.28 A1A2 = 0.22 A2A2 = 0.50 The...
