. Why does (or doesn’t) the frequency of a physical trait change in a rabbit population in different environments?
c. This is an important investigation as understanding how populations are affected by different traits helps to understand why certain species thrive in an a certain an environment and why others don’t. This is an interesting investigation as there are no predators in this investigation, the rabbits are competing for food and that is why they are dying at an alarming rate.
2a. I will test my design in different environments to determine if the frequency of a trait in a population changes over time in different environments.
b. I will investigate tail length. I’m interested in tail length as it is a physical trait that may or may not lead to the survival or destruction of the rabbit population.

In my investigation the mutation will be introduced before every generation, so the mutation will be prominent and there will be no doubt that it played a key role in the survival of the population. In one of the trial the mutation will be expressed as a dominant allele and in another trial, it will be expressed as a recessive allele.
e. I will conduct three replicates of this investigation. The number of trials is immensely important as it establishes a pattern that can be observed by other researchers looking to understand if rabbits having long tails will cause the population to adapt to having long tails to survive or resort to not having long tails as the trait is not the best for the longevity of the population.
f. For each trial I will need to run the simulation until the population of bunnies has died. For the mutated trial, it will be about 7 generations, and for the baseline trial it will be up to 15 generations. The number of trials is a biologically important variable in this investigation as it determines the length of the which in turn determines how effective the investigation is in regards to whether the mutation has a significant impact or

    Husky assembly team had a concern in regards to quality of gun drilled holes in columns today. The parts have deep spiral marks all the way thru the features. I understand that these holes can be difficult to manufacture and chips evacuation might be a challenge. Use of optimal cutting parameters and properly maintained tools should help to overcome the challenge. Please, let me know if Triumph made recently any changes to this process and verify condition of the tools.…

    Population Growth Lab Populations of different species interact with their environment in a myriad of ways. This may also impact the population, especially concerning its size. The question trying to be answered was how changes in the amount and nature of the plant life available in an ecosystem does, in fact, influence herbivore population growth over time. Answering this question will determine which environmental factor has the greatest impact on the population growth of herbivores. In this lab the herbivores, are rabbits, and the plant life is grass and weeds.…

    Taster Genotype Lab Report

    Five conditions must be met for the population to have a non-evolving gene pool: no mutation, random mating, infinite population size, no gene flow, and no selection (177-178). Within the student body, not all the conditions are met. The class is not an infinite population size, mating is not random, and there is gene flow. Despite all of this, we still use the Hardy Weinberg equilibrium as a base for the expected genotypes for the TAS2R38 gene. For the TAS2R38, there was a x2 value of .6325 and with one degree of freedom had a P-value well off the high end of the charts.…

    Predators affect the size in population . The population can either decrease or increase. If the population number increases then that means that the number of preys are high. The point of this lab is to figure out the factors of the stability and the unstability. The size of a predator population and prey population goes in a cycle over time.…

    Our group collected how the population changed overtime and see if one specie goes extinct in our experiment. We put the experiment on a specific time and also observed what changes if we change things differently, like the grass is off or on, and see if it’s a factor to the stability of a population. We made four trials and in each trials we compared it to one another and see how they are different…

    I will collect data on a single variable which will be the total rabbits with short tails in a population. I decided to design it this way because I am interested in seeing how well the rabbits survive in an environment with predators. b. The way I will keep track and organize my data will be writing it down on a chart. More specifically, a short tail population, a long tail, and a total population chart.…

    Due to the lynx being a specialist predator, even slight changes in the snowshoe hare will impact the population enormously. Furthermore, according to the 1998 studies, functional responses found of the lynx population in response to the snowshoe hare was that there was no evidence that the handling time of the lynx changed in accordance to the hare population dynamics. Moreover, the numeric response of the lynx population could be perceived in the pattern of the population graphs. During periods of hare population explosion, lynx population typically bloomed as well, and when time of population depression occurs in the hare community the lynx population will drop as well.…

    Another mistake was made when a group member knocked the dish containing the male flies in the F2 generation onto the floor. The flies were not yet counted or sorted by phenotype so the number retrieved from the floor could not be certain. This could be improved upon by limiting the number of people at the microscope at a time to avoid jostling or keeping a closer eye on where the dish is sitting. In the real world this experiment could be applied to many genetic trait and their inheritance. The lab is a simple way to show the complex reasons behind how phenotypes are determined and the links between generations and how traits can skip generations.…

    The null hypothesis stated that there is no difference in genetic variability or heterozygosity between the wild and founding populations. Based on the statistical Chi-square test comparison of genetic diversity between populations, the null hypothesis is valid and should not be rejected. The SPSS statistical results yielded a chi-square value of 0.773a and a P-value of 0.942 (Table 2). 0.942 is greater than 0.05, which means that statistically, there is no significant difference between the two populations. Thus, the wild and founding population are not different.…

    Traits are inherited in a variety of ways ranging from dominate or recessive and sex-linked or autosomal. Using different model organism, scientists are able to study inheritance patterns of many generations in a short period of time. Different model organisms are utilized in many different ways. In the case of this experiment, a model organism must have a rapid rate of maturation and reproduction. The use of Drosophila (fruit fly) was chosen for its fast gestation period and ease of trait comparison between generations (Cartier and Stewart, 2000).…
