Chapter 25.6, Problem 2CC
Summary Introduction
To describe: An evolutionary trend that might occur in Myxoma virus or rabbit when a rabbit population has its first encounter with the virus.
Concept introduction: Myxoma virus is a lethal virus that kills 98.8% of European rabbits exposed to the virus for the first time. Myxoma virus is used as a biological agent against the rabbit population in many countries.

BASED ON THIS TEXT:
Identify the biological process by which the malaria carrying mosquitoes (Anopheles coluzzi or Anopheles gambiae) developed insecticide resistance.

- Discuss Concepts Many city-dwellers have noted that the density of cockroaches in apartment kitchens appears to vary with the habits of the occupants: people who wrap food carefully and clean their kitchen frequently tend to have fewer arthropod roommates than those who leave food on kitchen counters and clean less often. Interpret these observations from the viewpoint of a population ecologist.arrow_forwardWhich evolutionary mechanisms (natural selection, mutation, genetic drift, or gene flow) would you need to understand to predict the success of genetically modified mosquitoes to: 1. Drive the mosquito population to extinction? 2. Replace the mosquito population with genetically modified mosquitoes that can not transmit malaria?arrow_forwardPanthers are also susceptible to a respiratory infection [feline calicivirus]. Individuals in a population, who are homozygous dominant or heterozygous for genes encoding parasite or pathogen resistance, are more likely to resist an infection or parasite. Currently, population estimates of the Florida panther range from 100 – 160 individuals. Let’s assume that the population equals 160. During a particularly bad calicivirus outbreak, 40 Florida panthers die as a result of the infection. Using this information, answer the following questions utilizing the Hardy – Weinberg equation when necessary. What is the most likely genotype of the affected panthers that died from the respiratory infection? Use the letter “A” for your symbol.

Hugo de Vries hypothesized that the characteristics were transmitted via some sort of particle that was given to the offspring by the parents. 2. The particle was dubbed as pangene by Vries. Number 1 is the first statement. Number 2 is the second statement. Both statements are true Only the second statement is truel Both statements are false Only the first statement is true It occurs when a population suddenly gets much smaller. This might happen because of a natural disaster such as a forest fire. genetic drift bottleneck effect founder effect natural selection Who proposed the three kingdom system? * Ernst Haeckel Carl Woese Robert Whittaker Aristotlearrow_forward1. What roles do natural selection and sexual selection play in the evolution of a new virus species? Give an example of this found in nature. 2. List the criteria for the Hardy-Weinberg Equation.

- Which of these statements about the virulence of rabbit myxoma virus is TRUE?A. Rabbit myxoma virus needed to become less virulent so it could coexist with its rabbit hosts.B. Directional selection favored a coevolutionary escalation where resistance evolved in rabbits and less virulence evolved in the virus.C. Rabbit myxoma virus became less virulent over time because natural selection favored strains that did not immediately kill the rabbit hosts, enhancing the likelihood of spreading and infecting other rabbits.D. None of the above is a true statement.arrow_forwardThe method of applying the molecular clock to determine the timing of the most recent common ancestor of HIV to 1930 was used to.... O 1. Test the hypothesis that HIV jumped from a bat population into humans 2. Test whether HIV was circulating in the human population at the same time as the Spanish Flu influenza A virus O 3. Calculate the divergence time between HIV-1 and HIV-2 O 4. Test whether HIV was spread through a contaminated polio vaccine in the 1950s O 5. Estimate the rate of evolution for all human retrovirusesarrow_forwardQ5. Which of the following is FALSE? If a genetic disease reduces fertility and the allele that causes the disease offers no other advantage, the allele will likely eventually disappear, due to natural selection. Natural selection does not favor individuals who are homozygous for the sickle-cell allele, because these individuals typically die before they are old enough to reproduce. Individuals who are heterozygous HbA/HbS are protected from malaria, and this is why sickle-cell anemia persists in wetter, mosquito-prone regions in Africa. O In regions where malaria does not occur, individuals who are heterozygous HbA/HbS have a selective advantage over those who are homozygous for the normal hemoglobin allele (HbA).arrow_forward
