For most cases, a p value of 0.05 is used to determine whether results fit expected values. Is this a magic number, or could p values be set more stringently, say 0.01, or more lax, say 0.10? What effect would these values have on the reliability of the chi-square test?

In a series of three experiments, M. G. Addo sought to use chi-square test to determine the goodness of fit at 5% for each of his results below. Carry out the calculations and determine whether the results obtained in each case are consistent with the 3:1 or 1:1:1:1 ratio he predicted in his hypothesis. Comment on your results.

The S-s antigen system in humans is controlled by two codominant alleles S and s. In a group of 3146 individuals the following genotypic frequencies were found:188 SS, 717 Ss, and 2241 ss. Is this population in equilibrium ? The frequency of S is ________________ and the frequency is s is__________________? Under equilibrium , the expected number of SS genotypes is_____________ andUnder equilibrium , the expected number of Ss genotypes is________________?
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?
Codominance ABO blood typing is an example of codominance, where A and B are both dominant to O. A woman who is AB type has a child with a man who is O type. Use I allele formatting to designate each genotypes: IA IA, IA i, IB IB, IB i, IA IB, ii A) List the genotype of each parent. B) Complete a Punnett square. List all the genotypes for the predicted offspring of this mating (using the format of genotypes listed above) C) What is the probability that any of their offspring will be O type? D) What is the probability that any of their offspring will be AB type?
Which of the following would NOT be characteristic of a single-source non-compromised STR profile? Group of answer choices A. No more than two (2) allelic peaks at any locus. B. Well-balanced heterozygote peaks. C. Sharply pointed peaks with even spectral distribution D. Well-defined smooth peaks with a bell-shaped distribution.
