- Download BLOSUM30 and BLOSUMB0 substitu- tion matrices and place them side by side on your computer screen. What are the differences between the two matrices? Why do you see these differences?The genotype at one CODIS Core Locus for the mother is (3,8) and for the father is (5, 7). Answer the questions below as they relate to that one CODIS Core Locus. Show your calculations and explain your logic. If a forensic profile is (7, 8) for this CODIS Core locus, what is the probability that one of the two sons will match at both alleles and the other will match at just one allele?Using the product rule, what is the total frequency of the profile, given the following genotype frequencies for each of the loci: D3S1358 = 0.04453 vWA = 0.02725 D5S818 = 0.07534 0.008406 0.0000914 0.14712 10,491 0.914208

- Secretors (genotypes SS and Ss) secrete their A and B blood group antigens into their saliva and other bodily fluids, while nonsecretors (genotype ss) do not. What would be the apparent phenotypic blood group proportions among the offspring of an IAIB Ss woman and an IAIA Ss man if typing was done using only saliva?Calculate the Chi square for cross 1 and cross 2 from the data in the attached image. Cross1: Phenotypes Ratio Observed Expected (O-E)2/E Totals X2 = Cross 2: Phenotypes Ratio Observed Expected (O-E)2/E Totals X2 =Coloured and white beads were carefully selected for equality of size and shape. Equal quantities of each colour were then placed in a container. Randomly select enough beads to fill the cover of a petri dish. Count the number of beads of each colour and record your data in table 1.6. Then calculate the expected numbers based on the sample size and the known ratio of white to coloured beads. Complete the table and calculate 32. Table 1.6 Chi-Square Calculations for Colored And White Beads Phenotype O E (O-E) (O-E)2 (O-E)2/E Colored White Totals How many degrees of freedom are there? Using table 1.5, what 32 values lie on either side of your calculated 32 value? What are the probability values associated with the 32 values? Briefly interpret the 32 value you have just calculated.
