Read the Lab 12 procedures and watch the online Hardy-Weinberg video (https://youtu.be/xPkOAnK20kw and posted on BlackBoard), then complete this assignment prior to lab.
The Hardy-Weinberg Theorem states
What are the five key assumptions that are necessary for the H-W Theorem to be valid?
Write the Hardy-Weinberg equation:
Dominant allele R has a frequency (p) of 0.45 in a particular gene pool. Calculate the following showing all your work and using the proper variables for each value (e.g. p, q, p2, q2, 2pg).
The frequency of allele r in that same gene pool?
The proportion of the population that has the genotype RR.
The proportion of the population that has the genotype Rr.
The proportion of the population that has the genotype rr.
If 17% of a population displays the recessive trait for Disease B, what are the frequencies of the recessive allele b and the dominant allele B in the gene pool?
You perform an experiment where you allow a large population of fruit flies to mate randomly. The parental generation had 30% homozygous recessive genotypes. The F1 generation consisted of 100 flies, 40 of which displayed the recessive trait. Calculate the expected values for each phenotype assuming Hardy-Weinberg equilibrium, then fill in the table below and use the Chi-Square test instructions document (posted online) to compare your calculated X2 value with the tabulated X2 value for a P-value of 0.05.
# of dominant phenotype individuals
# of recessive phenotype individuals
Observed value (o)
Expected value (e)
Deviation (o e) = d
d2
d2/e
Calculated Chi-square (X2) = ?d2/e
Degrees of Freedom
Tabulated X2 value at P=0.05
(from X2 instructions document)
According to your analysis above, are the observed proportion of genotypes in the F1 generation the same, or significantly different, than those expected according to the H-W theorem?
If you allowed your F1 generation to mate, what would you expect the frequency

I really appreciate the work all your amazing writers do to ensure that my papers are always delivered on time and always of the highest quality. I was at a crossroads last semester and I almost dropped out of school because of the many issues that were bombarding but I am glad a friend referred me to you guys. You came up big for me and continue to do so. I just wish I knew about your services earlier.

You can't fault the paper quality and speed of delivery. I have been using these guys for the past 3 years and I not even once have they ever failed me. They deliver properly researched papers way ahead of time. Each time I think I have had the best their professional writers surprise me with even better quality work. Elite Academic Research is a true Gem among essay writing companies.
Got an A and plagiarism percent was less than 10%! Thanks!
