- Which of the following is not an assumption of a population in Hardy-Weinberg equilibrium? The population is infinite in size All genotypes in the population survive and reproduce equally well The population is closed to migration from other populations No mortality is occurring in the population Individuals in the population mate randomly with respect to genotypearrow_forwardThree types of distribution patterns occur in wild populations of plants and animals. They are uniform, random, and clumped. Choose from the drop down menus the statements and examples of populations provided to identify the correct distribution patterns. Statements: Organisms are grouped together; occurs in highly competitive environments. No pattern exists in organism distribution; occurs in environments with little competition. Organisms are equally spaced apart; occurs in artificial environments. Examples: Orange trees grow in rows on an orange plantation. A large group of herring fish travel to their spawning grounds. Oyster larvae are dispersed over hundreds of kilometres by strong sea currents. Uniform Distribution Random Distribution Clumped Distribution Statement Answer Answer Answer Example Answer Answer Answerarrow_forwardIn populations of many organisms there is an inverse relationship between the density of individuals (number per area) and the average size of the individuals.

- In a hypothetical bug population, color is determined by a single gene and black is dominant over white. The frequency of the black allele is 0.1. If this population is in Hardy-Weinberg Equilibrium, what percentage of the bugs would we expect to be white? 81% 18% 9% 90% 10%arrow_forwardIn a hypothetical bug population, color is determined by a single gene and black is dominant over white. The frequency of the black allele is 0.1. If the population is in Hardy-Weinberg Equilibrium, what percentage of the bugs would you expect to be white? Please show your work.arrow_forwardIf a population were to remain in Hardy Weinberg Equilibrium, which of the following is correct? If a population were to remain in Hardy Weinberg Equilibrium, which of the following is correct? The population can still grow, but the allele frequencies will remain constant in each generation The population can still grow, but the allele frequencies may change with each generation Since it is at equilibrium, the population cannot growarrow_forward
- A population of 1,000 wild turkeys is studied and observed by scientists on an island. The scientists construct a study over five years to observe the temperature, amount of precipitation, daily value of berries individually consumed that were their exclusive food source, and available habitat for nesting. The scientist determined that as the climate changed, the population began to decrease. Using the Hardy-Weinberg Equilibrium as a null hypothesis, which of the following observations made by the scientists would support an associated alternative hypothesis? Due to the climate change, some birds may emigrate to a cooler location that would lead to a variation in the gene frequencies within the population. Variations in gene frequency due to advantages in natural selection would cause a greater number of males in the population to have more desirable traits. An increase in food consumption would cause the population to begin to exceed the carrying capacity that leads to a…arrow_forwardWhat is an example of a populations with organisms?arrow_forwardWhat is difference between species and population?arrow_forward
- Consider the 4 lines of data to be from the life tables of various species. Each one represents a different age class, and they report values for lx, dx, qx, and bx. Again, they are from different species. Which of the 4 choices would you say belongs to the species with the most intense age specific mortality? Group of answer choices l4 = 711, d4 = 211, q4 = 0.723, b4 = 0.98 l1 = 549, d1 = 242, q1 = 0.613, b1 = 0.08 l2 = 267, d2 = 199, q2 = 0.214, b2 = 1.28 l3 = 915, d3 = 377, q3 = 0.357, b3 = 2.90arrow_forwardThere are two traits in moths: light color and dark color. If a population has 60%of the moths with the light color, using Hardy-Weinberg, what can be predicted about the offspring of the population if no environmental factors are present? 40%of the offspring will be dark in color 40%of the offspring will be light in color 60%of the offspring will be dark in color 50%of the offspring will be each colorarrow_forwardWhich of the following would count as evidence that two populations are different species, according to the biological species concept?.arrow_forward
