While studying a emerging population of seals, you're asked to determine if the population is in Hardy-Weinberg equilibrium. Given the below data determine the chi square and whether the population is in H-W equilibrium. Choose the closest numerical answer for the chi-square value and either yes or no regarding whether the population is in HWE. AA - 45 Aa - 35 aa - 20 A chi-square critical values table is here (Links to an external site.). Group of answer choices 2.56 6.42 6.20 6.92 No Yes 3.45

Suppose that none of the 44 dolphins encounteredin the second sampling had been photographed before. Would you be able tosolve the equation for N? What might you conclude about population size inthis case?
One concept of conservation biology is known as minimum viablepopulation. Some species’ populations are so fragmented andsmall that they may have very little genetic variability left. Withminimal genetic variation in the population, there is little likelihoodthat a population can adapt to an environmental threat, such as anew disease. Florida panthers are at or below the minimum viablepopulation level (estimated population less than 80). 1)Do you think that it is practical to use limited resources toconserve a population like the Florida panther? 2)Why?
A founder population of interesting creatures is established, and the average probability of identity by descent is calculated for each subsequent generation as follows: Generation F 1 0.05 2 0.0975 3 0.142625 4 0.2283625 a) What are the effective population sizes Ne for each Generation 1 through 4, relative to Generation 0 (the founder population)? b) What is the effective population size of Generation 4 relative to Generation 3? c) Is there any evidence for changes in population size after the founder event, and if so, at which generation did the size change in the number of breeding individuals occur?
In an Inuit population in Greenland it was found that among 200 people, 168 were MM, 30 were MN, and 2 were NN. Is this population in Hardy-Weinberg equilibrium?
When the frequency of sitters is 0.75 (see Figure 6.22), the fitness of rovers is much higher than that of the sitters. So why don’t rovers quickly and completely eliminate the sitters in this population? Don't write from any online source..
The ability to roll your tongue is a dominant genetic trait passed on from generation to generation. Tongue rolling is the ability to roll the lateral edges of your tongue upward into a tube. The frequency of the tongue rolling trait was collected from 1,000 individuals each year 1925 to 2000 and is show in the data table below. Year Tongue Rolling Inability to Roll Tongue 1925 67% 33% 1950 68% 32% 1975 63% 37% 2000 67% 33% (a) Determine if the human population was in equilibrium from 1925 to 2000. Justify your response. (b) (b) Discuss how the Hardy Weinberg Principle can be used to determine whether this population is evolving (c) (c) Identify and describe THREE factors that would affect whether the population of Tongue Rollers is in Hardy Weinberg equilibrium. (d) (d) A scientist recently stated a claim that it is unlikely that the inability to roll your tongue will disappear from the population. Provide reasoning to explain…
tell whether the curves for the different cohorts are different from one another.If so, what might have caused the differences? In addition, did you notice any difference in the curves for males and females? If so, what might havecaused the differences?Speculate about the future if: 1) health care costs continues to increase, and 2) medical advances continueand most diseases and infant mortality are eliminated.How can this method be used to understand or manage natural populations?

The distribution of a herd of deer is shown in Fig. 4.17. Using the values below for the dimensions shown in the figure, estimate the population size of the deer using the number of animals per transect calculated from: the count from transect A only; the mean count from transects A and B; the mean count from all three transects A, B and C. Total Area (A) = 1,600,000 m2 (160 ha). w = 75 m L = 700 m Area of transect = 2wL
