Evaluation to population genetics data (Other (Not Listed) Sample) Content: Evaluation to population genetics dataName:Course:Tutor:College:Date:The genotypes of 200 unrelated individuals as indicated in the excel file was analyzed using the Arlequin Application by providing genetics with large set of statistical tests. The graphical interface illustrated show different data set with different perspectives. The genetic data is represented in the form of haplotypes from the haploid genomes analysis. Polymorphism information and gene match probability was analyzed using the Powestat software (Ehnholm. 1992). The genetic variants identified accounted for small part of heritability. The genome wide association of the wider sample was used to determine the remaining data set. The small part of the unrelated gene shows the proportion of the total variance in the polymorphism.As seen in the data set, the makers are polymorphic because the PIC values both denote the same value. The estimated haplotypes frequencies from the data show there is 56 haplo types and estimated 107 with no missing genotypes. The estimated result show haplotype frequencies are identical. Implementation of Stephen Al's Bayesian method is used since the haplotype frequencies is not to be included in the reporting phase. After analyzing the Arlequin implementations the 56 SNPS was analyzed with haplotyper implementations. The analyzed genotype showed that data sets with 125 subjects and 234 SNPS contained in one gene. Allelic diversity which provides unbiased estimates of the expected heterozygote frequency was computed. The genotype data was used to estimate the power of discrimination (Pakstis Castiglione 1997).Table 1Distribution of DlS80 alleles of 200 individualsAllele Number of observations Frequency1415 - -16 4 0.01017 5 0.01318 75 0.18819 - -20 10 0.02521 11 0.02822 17 0.04323 6 0.01524 163 0.40825 11 0.02826 12 0.03027 2 0..00528 22 0.05529 27 0.06830 3 0.00831 13 0.03332 6 0.01533 - -34 6 0.01535 2 0.00536 2 0.00537 1 0.00338 -394041The table shows the allele distribution at the D1680 locus. 21 different alleles are seen from the table with PCR amplification of the locus and high electrophoresis'. 18 and 24 have the most common alleles with frequency of 0.188 and 0.408 respectively while the rest having a value less than 0.10. 57 different D1S80 genotypes are observed. The m ost common genotypes was 24 with frequency of 0.150 and 18 to 24 with frequency of 0.145, the rest had a frequency no more than 10. In order for the data given to be utilized in forensic science, it should have Hardy-weinberg assumption. Due to the large number of genotypes in the sample, deviations from Hardy Weinberg would be impossible. From the chi- square analysis the result was there was no deviation from the Hardy- Weinberg. With pie= 6.28. p 0.25 and df=8. With a power of discrimination as 0.94, the heterozygosity was 0.80 of 0.781 + -0.029 which proves that the sample follows Hardy- Weinberg expectations.Table 2Distribution of DlS80 genotypes of the 200 individuals.Genotype/ No. genotypes Frequency/Genotype/No. of genotypes Frequency16-18 0.005 21-29 0.01016-22 0.005 22-24 0.04516-24 0.005 22-27 0.01016-28 0.005 22-28 0.00517-24 0.015 22-29 0.00517-29 0.005 23-24 0.01517-31 0.005 23-26 0.00518-18 0.040 23-34 0.00518-20 0.005 24-24 0.15018--21 0.005 24-25 0.02018-22 0.015 24-26 0.04018-23 0.005 24-28 0.05518-24 0.145 24-29 0.07018-25 0.015 24-30 0.00518--26 0.005 24-31 0.02518-28 0.015 24-32 0.02518-29 0.025 24-34 0.00518-30 0.005 24-41 0.00518-31 0.010 25-26 0.00518-32 0.005 25-28 0.00518.-34 0.010 25-29 0.00518-35 0.010 26--28 0.00518-36 0.010 28-31 0.01518-37 0.005 28-34 0.00520-20 0.005 29-29 0.00520-21 0.015 29-31 0.00520-24 0.020 30-41 0.00521--24 0.020 31-34 0.00521-25 0.005The sampled allele is suitable for forensic analysis ranging from 16 to 41. The PCR amplified the tandem copies of the repeated motif. 21 alleles and 47 genotypes in the population sample. This type of allele distribution has been detected in various countries: Japan, Netherlands, Spain Denmark, Finland and American Causians as seen in the table the frequencies of the allele is from 0.181 to 0.307 and 0.224 to 0.414, with the uncounted alleles having frequencies less than 0.1. From table 2 the alleles of 18 and 24 are 0.124 and 0.23 which shows the frequencies to that in Chinese and American. As shown in the Recordings from global Genotype distribution.
