You are studying a population of squirrels in a city park in McMinniville Tn,. You are interested in this population because it contains some albinos (caused by a recessive allele for fur color). Recent studies in rural areas have shown that albino squirrels suffer predator mortality at a higher rate than normally colored squirrels. You want to know if natural selection acts on albinism in a city park in the same manner that it does in the wild. You go to the park, shot all 120 squirrels in the park, and sample their DNA. From these samples you determine that:
68 were homozygous dominant (B,B)
28 were heterozygous (B,b)
24 were homozygous recessive (b,b)
Use the Chi Square Goodness of Fit Test to test the Null hypothesis that this population is not undergoing natural selection for fur color. If you conclude that it is experiencing natural selection, state whether albinism is being selected for or selected against.

2. Imaginary scenario: You are walking in an alpine meadow. You notice a population of "Icelandic Musky Marmots". This species is interesting because it exhibits two very distinct fur color phenotypes: 1) brown back with yellow belly, and 2) yellow all over with brown stripes. Individuals with the fur color combination brown back + yellow belly + brown stripes are never observed in the population. Individuals with the fur color combination yellow back + brown belly are never observed in...

1. You are studying a population of sandblossoms (Linanthus parryae) that has individuals with blue and white flowers. The allele for white flowers (A) is dominant to the allele for blue flowers (a). In the population you survey, 91 out of 100 individuals have white flowers. Based on this information: a. Calculate the frequency of the A and a alleles. b. Calculate the numbers of each genotype. 2. A population of snapdragons (Antirrhinum hispanicum) has two additive alleles for flower...

On the island of Notion, in the Factotum Archipelago, there lives a population of pencil bears. A portion of these bears have silky fur, and as a result, are much better surfers. The texture of the fur is determined by a single autosomal locus with two alleles: S (trait allele) and s (wild type allele). In a recent study, researched collected the values in the following table: Table 1. Counts of Pencil Bear fur style by genotype Phenotype Genotype Silky...

In a population of wild sweet pea plants that you assume are in Hardy-Weinberg equilibrium, 1% of plants express a recessive white flower color. A) What is the expected frequency of heterozygotes in the population? Number You have noticed a shift in pollinator frequency and you want to test whether this has resulted in selection on flower color. You sample 1000 plants and genotype them at this locus. B) How many of each genotype do you expect based on the...
