Heterozygosity is important in a population because genetic diversity is a good measure.. Genetic drift has more pronounced effects of small population. Where as some population genetic drift go through a risk named allele fixation. In this one allele occurs at 100 percentage frequency & others lost entirely. It results complete loss of heterozygosity.. .

QUESTION 4 1 points Save Answer One metric of genetic diversity in a population is heterozygosity, i.e., the frequency of heterozygotes. For the marker(s) that are not in Hardy-Weinberg equilibrium, does the difference between Ho and He indicate increased or decreased heterozygosity for those markers? Increased heterozygosity Decreased heterozygosity QUESTION 5 2 points Save Answer Select all the mechanisms of evolution that could explain the deviations from H-W expected frequencies for those markers, based on the difference in heterozygosity? Selection...

One major concern in conservation biology is the loss of genetic variation in small populations due to genetic drift via bottlenecks. If a drastic bottleneck reduces the size of the population to 12 which had an initial heterozygosity of 0.38, How much of the initial heterozygosity will be lost after one generation? After the bottleneck If the population size remains the same in each following generation how much of the initial heterozygosity will remain after 10 generations?

A population of timber rattlesnakes in eastern Kentucky is surveyed to estimate genetic diversity and structuring of the species across the landscape. Six populations are tissue sampled and are genetically analyzed; these appear to be metapopulations that are fragmented and separated by surface mining. The following data describe the distribution of genetic diversity within this population. HP = 9%; DPT = 91%. Explain these findings and why they may or may not be important knowing that 3 of these 6...

3. You are part of a restoration ecology program that is attempting to reintroduce endangered European bison, Bison bonasus, into to suitable habitats in the Eurasia. This species went through an extreme bottleneck after they were almost wiped out during WWI. Maintaining what limited genetic diversity remains is an important priority, especially because diseases spread from cattle represent a major threat. A remote site for reintroduction has been identified in Belarus. Captive-bred bison destined for this site have been genotyped...

Research diversity expert Martin Davidson, author of “The End of Diversity as We Know It: Why Diversity Efforts Fail and How Leveraging Difference Can Succeed”. What is his direction for “how you adopt a leveraging difference mind-set? (There are three actions that can be instrumental in helping leaders transform how they approach difference!) Name them and tell us how you as a team leader might facilitate the process?

because real life populations, are, of course, not infinetly large, why is the hardy-weinberg condition of an infinitely large popualtion usually met for natural population? none drift naturally happens in every population most natural popualtions are large enough that chance favtors have negligible effects on allelic frequencies most population are anyway not following any of the 5 assumptions
