    A ship was caught in a storm and driven to a small island in the middle of the South Pacific. For generations, no one encountered this small colony, who despite the odds made a thriving settlement on their island. After many years, what characteristics would be unique about this population? A: The people on the island would all look very different from each other, and they may have evolved some odd characteristics that aren't seen in other humans. B: The...

    1) Suppose that on a small island off the coast of Scotland, 32 percent of the population has blue eyes, which means that these individuals must be homozygous for the blue eye color gene (bb). The only other eye color found on the island is brown, and individuals that are homozygous for the brown eye color gene (BB) or heterozygous (Bb) will have brown eyes because brown is the dominant gene. Assume this population is in Hardy-Weinberg equilibrium. If 100...

    Stochastic Population Growth Model Next, we are going to monitor the population growth of an asexually reproducing single-celled organism, centinia lincolni (pennies). This Centina population has a mortality rate of 50% per year, but all individuals that survive the year divide to produce an additional individual. The very most basic growth model of a closed population is: N+ N-deaths births Rewritten to use rates instead of individuals, this equation becomes: N+ -N,S+N.BS where S is the probability of survival (0.5)...

    please help me with these problems. thank you Introduction The Island of Daphne Major, one of several islands that make up the archipelago of islands off the coast of Ecuador, supports a population of ground finches, Geospiza fortis. Finches are small songbirds with chunky beaks which they use to crack open seeds from various shrubs and trees on the island. These seeds make up most of the finch diet. Biologists have been studying this population for over 30 years. Each...

    For this exercise we will be re-enacting founder effect on a population of hypothetical people. You can use red and white beans (or any other small household item that comes in two colors) to complete the exercise. The beans will represent genes and the different colors will represent different alleles (gene variants). Red beans will represent the dominant (R) allele for the trait, while white beans will represent the recessive (r) allele. Humans have two copies of each gene, so...

    4) (8 points) Assume that a population of newly discovered small creatures called "porgs" in a remote island lays eggs with three distinct appearances: patterned with dots, white, or dark grey. Last year, the porgs laid 30 dotted eggs, 40 grey eggs, and 15 white eggs. You randomly selected 25 eggs, 10 of which were dotted, 13 were grey and 2 were white. Based on this information, please answer these questions a) (2.5 points) What is the probability that you...

    1.While working on the coral project, you notice that each coral population tends to have its own population of parrotfish that eat the large algae that can grow on corals and smother them. One population of parrotfish seems to be doing a poor job of eating the algae and the parrotfish seem skinny from their inefficient feeding. This fish population also seems to be much smaller that the populations at the other two coral sites and the fish all look...

The freshmen and sophomores fill the Treasurer and Secretary positions, while the juniors and seniors fill the Vice President and President's positions. If there are 14 freshmen and sophomores running and 20 juniors and seniors running, how many student councils can be formed? Jake has two different bags of candy.

    You have a cup of beans in front of you with 20 white beans and 24 red beans. These beans represent the alleles for a simple Mendelian trait, where red is dominant (R) and white is recessive (r). In 1997, a self-isolated group of people living on a small island was joined by a group of explorers from a nearby island. STEP 1. Create the original, self-isolated population. The self-isolated population consists of six males. Three of them are homozygous...
