Part 3 – Calculating allele frequency changes and Hardy-Weinberg proportions

The observed genotype frequencies will be posted on blackboard as an announcement during class. The excel-based Hardy-Weinberg calculator (HWE.xls) will be helpful for filling out the table below.

Focus on the dark colour soil population and calculate allele frequencies, frequencies of heterozygous individuals, etc.

Simulation step	#DD	#Dd	#dd	Observed frequency of D allele	Observed frequency of Dd individuals	Expected frequency of Dd (assuming HWE)	Chi-squared value*
Starting conditions	250	500	250
After natural selection in a heterogeneous environment	240	492	127
After random mating	328	489	191
After gene flow between two populations	305	480	219

For this project, you are to modify the Employee class posted on Blackboard by adding a bonus field. The bonus field should be equal to zero when an Employee object is created. You need to add a setter and a getter method to the new bonus field. The Dirany’s company saves all employee information in the dirany.txt file (attached). The file saves each employee’s information in a new line and all attributes are separated by tabs. For example, the first...

You obtain three samples from three different populations. Observed genotype frequencies. Population 1 AA=0.70 ; Aa=0.25 ; aa = 0.05 Population 2 AA=0.35 ; Aa=0.55 ; aa=0.10 Population 3 AA=0.45 ; Aa=0.40 ; aa=0.15 Populations 2 and 3 have no barrier between them. But populations 1 and 2, and populations 1 and 3 have a barrier between them. What are the FST values between these three pairs of populations?

Suppose you used allozymes to estimate allele and genotype frequencies in a natural population as we discussed in class. Now suppose there were a number of silent mutations occurring. Can these be detected using allozymes? What influence would the presence of silent mutations have on your estimates of allele and genotype frequencies from allozyme data?

Question

The observed genotype frequencies will be posted on blackboard as an announcement during class.
