How many unique gametes could be produced thorugh independent assortment by an individual with the genotype AaBbCcDdEe? Answer is 8 why? Aristotle: Lamarck: believed in evolution Linnaeus: taxonomy Cuvier: Hutton: All known organisms transcribe genetic (nucleotide) information to protein molecules wia the same genetic code. This finding strongly supports the hypothesis that A. theres only one possible way to encode information in a macromolecule- not a hypothesis B. the earliest macromolecules probably arose when lightning struck an oxygen free atmosphere.- not true C. all organisms are descended from a single common ancestor- true. It is believed that all organisms derived from a single common ancestor therefore C is correct D. the genetic code will never be broken.- not hypothesized or true E. none of the above.- c is right At a locus with a dominant and a recessive allele in Hardy Weinberg equilibrium, 9% of

Unformatted text preview: the individuals are homozygous for the recessive allele. What is the frequency of the dominant allele? Work it out [ .09= aa= p2. p= square root of .09 = .3. 1-.3=q=.7 therefore frequency of a=70%] Mutation and sexual recombination generate variation, while natural selection results in adaptation to the environment. Kinesis is a change in activity whereas a taxis is a directional response to a stimulus. Which of the following is NOT true about macroevolution? A. It is less controversial than microevolution- it is more controversial because it deals with a larger perspective B. It includes evolutionary change at or above the species level.- this is the definition C. It is not goal oriented.- surely isnt D. It frequently involves the recycling of features for new uses- yes E. it often leaves baggage behind- sure...
