Question 1: What is NOT a force of evolution?
Mutation of genes
Genetic drift
Equilibrium of populations
Migration of populations
Question 2:
Crossing true breeding dark-coated sheep with true breeding light-coated sheep always results in 100% dark-coated offspring. You are screening a population of 300 Soay sheep for coat color, and you count 243 dark sheep and 57 light sheep. What is the genotype frequency of the homozygous recessive sheep for TYRP1 gene if the population is in Hardy-Weinberg equilibrium?
.421
0..176
0.864
0.190
Question 3:
In the same population, if it is under Hardy-Weinberg equilibrium, how many individuals do you expect to be heterozygous at TYRP1?
217
0.492
148
124
Question 4:
Rabbit’s ears can be either short (dominant) or floppy (recessive). If a population of rabbits in Hardy-Weinberg equilibrium has 250 short eared rabbits and 100 floppy eared rabbits, what is the allele frequency of the “short” allele?
.465
0.714
0.845
0.535
Question 5:
To calculate degrees of freedom, we use the following formula: Degrees of freedom – the number of constraints imposed on your comparison. How many constraints are there when we use the Chi-square test for Hardy Weinberg equilibrium?
1
2
3
0
Question 6:
You perform a Chi-square test for gene X and find the p-value to be greater than 0.05. What can you say with 95% certainty about this population?
This population is in Hardy-Weinberg equilibrium at the X locus: gene X isinfluenced by at least one force of evolution.
This population is in Hardy-Weinberg equilibrium at the X locus: gene X is notinfluenced by any forces of evolution.
This population is not in Hardy-Weinberg equilibrium at the X locus: gene X isinfluenced by at least one force of evolution.
This population is not in Hardy-Weinberg equilibrium at the X locus: gene X is notinfluenced by any forces of evolution.
