The degree of freedom in chi-square analysis is usually calculated by df= (r-1)(c-1).
Row = Blood type, Column = Alleles.
df (degree of freedom) =(The number of values in row -1)*(the number of values in column -1)
df= (3-1)*(3-1)
df=4.

- While studying the frequency of sickle-cell disease ("sickle cell anemia") in a population living in sub-Saharan Africa, you obtain the following data from a sample of n= 100 people (note that I chose a simpler system for identifying the alleles rather than using "Hb S" for sickle cell allele), which is the actual name and what you used in lab). What is the frequency of the sickle cell allele (b) in the sample below from a human population? Sample Data BB-60 individuals (No sickle cell disease) Bb-30 individuals (No sickle cell disease) bb-10 individuals (Sickle cell disease) 1. 0.25 2. 0.10 3. 0.35 4. 0.60 5. 0.20A total of 6129 North American Caucasians were blood typed for the MN locus, which is determined by two codominant alleles, LM and LN. The following data were obtained: Blood type Number M 1787 MN 3039 N 1303 Carry out a chi-square test to determine whether this population is in Hardy–Weinberg equilibrium at the MN locus.In an island population, the following data were obtained for thenumbers of people with each of the four blood types:Type O 721Type A 932Type B 235Type AB 112Is this population in Hardy-Weinberg equilibrium?

- A sample of 600 individuals from a population is examined for the presence of the HindIII polymorphism in an autsomal Sca gene. There are two alleles of Sca gene, A and a. The results are 14 individuals are AA, 212 are Aa, 374 are aa. Please answer the following questions accordingly? How many alleles are present in the gene pool in the sample population fort he Sca gene? What are the genotype frequencies? What are the frequencies of A and a alleles? What are the expected numbers of the three genotypes, assuming random matings.. A gene called Q has two alleles, QFand QG, that encode alternative forms of a red blood cell protein thatallows blood group typing. A different, independentlysegregating gene called R has two alleles, RC and RD,permitting a different kind of blood group typing.

After one generation of random mating, what fraction of the next generation of football fans will…The basis for rejecting any null hypothesis is arbitrary. The researcher can set more or less stringent standards by deciding to raise or lower the p value used to reject or not reject the hypothesis. In the case of the chi-square analysis of genetic crosses, would the use of a standard of p = 0.10 be more or less stringent about not rejecting the null hypothesis? Explain.
