Question

The following data was obtained from a previous BIO 340 class. Data obtained from reference papers regarding the USA population are also provided and will be used to determine the “Expected” frequency and counts. You will have to analyze the data and provide phenotype, genotype and allele frequencies as well as perform a chi-square analysis. Complete every single empty square (up to two decimals required).

Use the Chi-square stable, which can be found in the Chi-Square Analysis of Mendel's Data page of your online textbook as well as in the Module IV Chi-square analysis lecture, in order to determine if the null hypothesis (H0) for each of the Test papers is rejected or not. Write down your answer next to each of the compounds.

Sodium benzoate H0=

Phenyilthiocarbamide (PTC) H0=

Thiourea H0=

How do the BIO 340 results compare to those of previously published data from the USA population? Did you expect these results? Explain why.

Mention 3 reasons why most populations are not in Hardy-Weinberg equilibrium:

1)

2)

3)

Explanation / Answer

The three reason why most populations are not in Hardy -Weinberg equilibrium :

1) No population is infinitely large.

2) Spontaneous mutation cannot be prevented.

3) Selection and migration pressure equally exist among in most natural populations.
