In a population of lynx, a census was taken in the spring and again a year later. In the spring, there were 400 baby lynx born, of which 300 had a normal speckled coat phenotype and 100 had a black phenotype. A year later, there were 200 speckled coat lynx and 50 black lynx that had survived to adulthood. Calculate the survivorship for each phenotype, and determine the relative fitnesses based on survivorship. What is the relative fitness of the black fur phenotype (wb)?
a) 0.00 < w < 0.25
b) 0.25 < w < 0.50
c) 0.50 < w < 0.75
d) 0.75 < w < 1.00
In this version of the simulation (500 population size; 500 carrying capacity), all fish are equally likely (though not 100% likely) to survive and reproduce. There are no mutations, nor are there any entering or leaving the population. When they reproduce, they choose a mate from the pool at random and produce ten offspring by chance with the probability of the offspring’s genotypes determined by the punnett square. What caused the allele frequencies to change and vary in the trials? (ex attached).
Does Figure 6.5(C) use relative fitness or absolute fitness of the horned lizards in calculating the fitness function? How can you tell from the graph?

- There 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_forwardTwo human populations have the same net reproductive rates (R0), but different generationtimes.

- n 1978, scientists studied how the fitness of marine sticklebacks would be affected if they were introduced into a freshwater environment. They collected 90 male and 90 female sticklebacks from a marine population and 10 male and 10 female sticklebacks from a freshwater population. The 200 sticklebacks were introduced into a freshwater environment that had no stickleback fish previously. Which of the following best describes the likely results of the scientists’ investigation of the fitness of the sticklebacks that were originally from a marine environment? The fitness of the sticklebacks from the marine environment increased because their chance of survival and reproduction is greater in the freshwater environment than in the marine environment. Answer A: The fitness of the sticklebacks from the marine environment increased because their chance of survival and reproduction is greater in the freshwater environment than in the marine environment.

Correlation coefficient = -0.1 Number of predators From the correlation analysis, is there strong evidence that the number of predators affects the number of parrot chicks? Yes, because the number of chicks decreases as the number of predators increases. No, because the correlation coefficient is close to zero. Yes, because correlation analysis is used to determine the effect of one variable on another. No, because correlation analysis does not determine if there is a causal link between the two variables. Number of parrot chicksarrow_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.
