Working version of the 1st lecture exam, as of 19 January 2014 1. Science can prove hypotheses to be false because: 2. In a population: phenotype Average number of offspring per individual Very small nose 5. 5 Small nose 6. 0 Medium size nose 10. 7 Large nose 20. 7 What is the relative fitness of organisms with small noses? 3. In the above population, assuming that at one time the population followed a normal curve for nose size, which mode of selection occurred? . Bobbie is conducting an experiment evaluating the performance of sunflower lands from seeds produced during the winter and sunflower plants from seeds produced during the summer. Babies null hypothesis is: 5. The prediction for which Darwin had evidence that is similar to our modern evidence is: 6. In a population of plants, the following data are collected. Time 1 2. O.

Lower 10. There are two deterrent ways the water snail, Alumnae prepare, can coil: textural and Sinatra. Textural coiling is caused by the dominant allele (D) and Sinatra is caused by the recessive allele (d).

Although this is a completely dominant trait, the genotypes of all individuals in a population were determined yielding the following data: AD ad Conduct a X square test to determine if the population is evolving. Show all your work. In your answer, be sure you 1. Clearly state your hypothesis, 2. Omelet the X square table 3. Indicate the degrees of freedom 4. State the P value, 5. Interpret the P value, 6. State if you reject or fail to reject your hypothesis, 7. State if this population is evolving or not. 8.
