You’ve sequenced 1000 bp of your favourite gene from 5 haploid individuals

Allozyme genetics exercise

[Data_Source]: Allozyme_genotypes.txt; The data file consists of diploid genotypes for 20 fruit flies at 5 allozyme loci (EST1 to EST5) sampled from many populations. Please find the population assigned to you (Data_Assignment.txt). Each distinct allele at a locus is given a unique number (e.g. 12 = heterozygous individual with allele 1 and allele 2). There is a maximum of 3 alleles per locus.

Analyse the data to estimate the parameters below

1. Allele frequencies (p1,p2,p3)

2. Number of Alleles/Locus, a

3. Observed Heterozygosity / locus Hobs

4. Expected Heterozygosity / locus Hexp

5. Proportionate reduction in heterozygosity due to inbreeding, Fis

6. x2 for HWE test

7. df for HWE test

8. p value for HWE test

Provide me with a completed table like below; report 2 decimal places for all estimates, but keep 3 decimal places while doing the calculations


Is your population inbreeding: Yes / No

Back up you answer with evidence (2 to 3 lines):

Sequence analysis exercise:

You’ve sequenced 1000 bp of your favourite gene from 5 haploid individuals. The dataset specifies all polymorphic positions in the sequences (their location does not matter here). Estimate the following parameters;

1. Proportion of Segregating Sites, S [3 decimal places]

2. Number of mismatches at each segregating site, presented in the same order as in the dataset and separated by commons [eg: 3,4,4,3,…]

3. Nucleotide diversity, π [4 decimal places]

Hint
StatisticsAllozymes genetics is a form of enzymes that varies structurally but remains functionally independent from other alloys coded by different locus. Common in enzymes with high evolutionary conservation .they are used as markers in phylogenetic....
