Which female in an ant colony is the only fertile reproductive ant? ____________ 4. Female ants differ from male ants because the female ants are ________________ while the male ants are _________________. 5. How often does the fertile female ant of a colony mate? ____________________ 6. Each female ant receives ____________ copy/copies of the female parent genome. 7. Female siblings, on average, share _____________% of the genetic information they received from their female parent. 8. Female siblings share _____________% of the genetic information they received from their male parent. 9. On average, female sibling ants share ____________% of their entire genomes in common. 10. Worker ants can propagate their genes indirectly by ____________ the queen ant. 11. In this lab you will be investigating whether or not the ants show a preference for their own soil or __________________________ and whether or not they show a preference for their own soil or _______________________. 12. You should be careful when handling the ants because they can inflict a painful _____________ on the unwary. 13. What kind of hypothesis will you be testing in the lab? ___________________________ 14. State specifically the hypothesis that you will be testing: 15. How long will you observe each individual ant? ___________________________ 16. How many ants (n) will make up the initial small samples? __________________ 17. How many ants (n) will make up the pooled sample? _______________________ 18. What kind of statistical test will be performed on the data? __________________________________ 19. What happens to the null hypothesis if data are significant? __________________ 20. What happens to the null hypothesis if the data are not significant? _______________________________ 21. If the calculated T value was smaller than the appropriate T value in the Wilcoxan Signed Rank test table, what would do with your hypothesis? ______________________________ 22. If the ants have no soil preference in this investigation, how often would you expect to observe them on the non-nest soil samples? ___________________________ 23. How might the ants recognize their own soil from a sample taken from else where? __________________________________________________________ 24. At what level of significance are we testing these data? _____________________ 25. If the data are statistically significant, what is the probability that these data reflect a sampling error and are actually not significant? _____________________ 26.
