Index of Slides : Graphic Version 800x600

  1. GENETIC LINKAGE
  2. Independent Assortment
  3. LINKAGE
  4. LINKAGE & parental types
  5. Meiosis with no crossover
  6. Recombination fraction, r, is a variable with a different value for each pair of loci.
  7. Estimating r & map distance
  8. r = (86+44)/(86+44+4292+4605)= 0.014, so 1.4 map units
  9. No Title
  10. An Example of Linkage
  11. Linkage of height and hairiness
  12. EVALUATING GAMETIC PROPORTIONS with test cross
  13. Observed proportions are not compatible with equal amounts of each gametic genotype.
  14. Expected equalities
  15. Getting a Value for r
  16. If the F1 had Sg/sG genotype then the following is a typical result.
  17. No Title
  18. Crossing over in 3 linked loci
  19. 3 linked loci (ordered HQR)
  20. Ordering loci on a chromosome
  21. CONSTRUCTING THE MAP
  22. Bacterial GENES
  23. Bacterial SEX
  24. LINKAGE RECAPITULATION
  25. Vocabulary
