Q6.4. What is the effective size of a population? The size of a population with the same heterozygosity as the actual population, but which does not lose heterozygosity over time The size of an idealized, randomly mating population losing homozygosity at the same rate as the actual population The size of an idealized, randomly mating population losing heterozygosity at the same rate as the actual population The size of a randomly mating population with the same sex ratio as the actual population

Q8 -You sample 1000 lizards in a very large population. Every individual you have sampled is brown. You conclude that all lizards in this population are brown. This is deductive reasoning.true or false? -Suppose all sex-changing fish are from coral reef habitats. You discover a wild-caught sex-changing fish in a fish store. You conclude that this fish was harvested from a coral reef. This is inductive reasoning. true or false? -Populations that live in areas with high ecological mortality reproduce at younger ages than similar species living in areas with low ecological mortality. You decide to run an experiment comparing two populations. The environment of population 1 has many predators, parasites, and pathogens; the environment of population 2 is free of predators, etc. You predict that population 1 will reproduce at a younger age than population 2. This is deductive reasoning. true or false?
37. When 2 different species are competing for a resource, in the absence of other factors, one will usually win because the competition is asymmetrical. That is because: One species usually cheats. Populations have different numbers of individuals. Different species have different morphologies (how they look) and physiologies (how they function). All of the choices are true.
Need help Please answer both.All it is one question. 1. List down and describe methods used for marking animals in population estimate studies? 2. What would be the effect of the following circumstances on your estimate of population size, P? Will your estimate be too high or too low in each of the following situations? 1. some animals lose their mark 2. marked animals have higher death rates 3. marked animals hide 4. marked animals are sluggish 5. immigration occurs
77)Each graph below shows the frequency of the A allele in six simulated populations (each line in a graph) over 500 generations. Each of the six simulations within a graph were done with the exact same settings of relative fitness among the genotypes and population size BUT these settings differed between the four graphs. Which graph shows a situation in which the effect of selection is the highest relative to the effect of drift? C D A B
Scenario 1In the 1960s, a population of squirrels (Sciurus carolensis) was being studied in Alabama and the coat color of the squirrels was found to range from the more common gray color (dominant) to the less common red color (recessive). When they sampled an area, they found 536 gray squirrels and 64 red squirrels. Assume that the population is at Hardy-Weinberg equilibrium. 3A. Show your work to find the number of heterozygous squirrels.
Scenario 2In the year 2015, another group of scientists studied the squirrel coat color and found that the population of squirrels had increased. They found 850 squirrels in the same area, of which 115 had a red coat. Assume that the population is in Hardy Weinberg’s equilibrium. 4A. Show your work to identify how many of the 850 squirrels would be expected to be gray.
Question 51 of 51 Click Submit to complete this assessment. Question 51 You have been doing extensive research for 30 years on the frequency of coat colors (black, gray, white) in a guinea pig population located in the Andes Mountains. You suspect that your guinea pig population is undergoing stabilizing selection. If this is the case, what would you expect to find when you graph your data? Select all that apply.A) Two peaks, one at each end of the graph.B) A graph with a single peak towards the far right.C) A graph with a single tall and narrow peak located in the center.D) A graph indicating gray guinea pigs have an advantage over black guinea pigs and white guinea pigs.E) A graph indicating that gray guinea pigs are being selected against.
The population is an important unit in ecology as well as other biological sciences. How is a population defined, and what are the strengths and weaknesses of this definition? Are there some species that at certain times or places are not in populations?
