a)It is impossible to answer this question with the information provided.b)My orchard sample was at Hardy-Weinberg equilibrium.The observed orchard genotype frequencies were the same as the expected genotype frequencies.c)My orchard sample was not at Hardy-Weinberg equilibrium.The observed orchard genotype frequencies were the same as the expected genotype frequencies.d)My orchard sample was at Hardy-Weinberg equilibrium.......
I am interested in determining whether a local population of fruit flies (Drosophila melanogaster) is at Hardy-Weinberg equilibrium, so I recently visited a local orchard where I collected 100 individual flies, and took them back to the lab. There, I sequenced the DNA of each fly to determine their specific genotype at the autosomal gene locus that codes for alcohol dehydrogenase (ADH; an enzyme that is necessary for flies to metabolize and detoxify ethanol).

The results of this study revealed that there were 75 individuals that were homozygous for the dominant allele E, 10 individuals that were heterozygous, and 15 individuals that were homozygous for the recessive allele e (and are thus incapable of metabolizing and detoxifying ethanol).

Based on your answer to the previous question (expected frequencies of genotypes at Hardy-Weinberg equilibrium), was the sample of 100 parental flies I collected from the orchard at Hardy-Weinberg Equilibrium?

a)It is impossible to answer this question with the information provided.


b)My orchard sample was at Hardy-Weinberg equilibrium.

The observed orchard genotype frequencies were the same as the expected genotype frequencies.


c)My orchard sample was not at Hardy-Weinberg equilibrium.

The observed orchard genotype frequencies were the same as the expected genotype frequencies.


d)My orchard sample was at Hardy-Weinberg equilibrium.

The observed orchard genotype frequencies were the not same as the expected genotype frequencies.


e)My orchard sample was not at Hardy-Weinberg equilibrium.

The observed orchard genotype frequencies were the not same as the expected genotype frequencies.

It appears that the observed ratios were not in agreement with the expected ratios.
Observed ratios: ee = 0.15, Ee = 0.10, EE = 0.75
Expected ratios: ee = 0.15, Ee = 0.4746, EE = 0.3754
Therefore, it can be concluded that the population was not in equilibrium.
