How would you recognize Blights?
-term blight properly applies to rapidly spreading and extensive necrosis of plant foliage due to generalized invasion by a pathogen-word 'blight' is often used in the names of diseases more appropriately classified as leaf spot/limited lesion diseases-blights are mostly caused by fungi and bacteria

What would happen if the Hardy-Weinberg assumptions were violated?
Well, they usually are not true, and thats the point. allelic frequencies can and do change over time. But often times, these are just fluctuations. some traits could theoretically be eliminated from a population as well. (perhaps if there was a very few number of individuals or the trait was extremely disadvantageous.)

Life Tables
Life tables take into consideration: survivorship (l), the percentage of individuals that live to a certain age; and fecundity (b), the average number of female offspring one female has during her time in that age bracket.Multiplying l x b gives the age class specific contribution to reproduction (lb) for each age group.To find the net reproductive rae (R), we sum up all the l x b values.If the population size is stable, the R value is one. If it is growing, it will be greaer than one. If the population is in decline, it will be less than one.

What 4 points should you keep in mind when classifying diseases?
1)-some diseases may not readily fit into any of the groups presented-merely emphasises the fact that classification is an artificial process-in order to accommodate all diseases more readily, some groups might be split or new groups added2)-some diseases may fit more than one group, again illustrating how artificial classification is3)-some diseases may fit into one or anothe group according to environment conditions-predisposition of the host by weather favourable to the pathogen may result in more severe symptoms4)-some groups are not only based on symptoms, but also on parasite taxonomy-in several cases, members o particular taxa of fungi all induce similar symptoms on the host
