| 1. Dihybrid cross (corn) |
| · Recessive alleles |
| · Linkage |
| · Recombination |
| · Cis arrangement |
| · Recombination frequency, map units |
| · Using F2 progeny ratios to determine map units |
| · Using map units to determine F2 progeny ratios |
| |
| 2. Dihybrid cross (FlyLab: forked and scalloped) |
| · X-linked recessives in cis |
| · Test cross vs sibling cross |
| · Recombinants and parentals |
| · Map distance |
| |
| 3. Dihybrid cross (FlyLab: forked and miniature) |
| · X-linked recessive |
| · Cis vs trans |
| · 3 two factor crosses to build map (forked, scalloped and miniature) |
| |
| 4. Dihybrid cross (FlyLab: spineless and incomplete) |
| · Autosomal recessives |
| · Test cross |
| · No recombination in males |
| |
| 5. Trihybrid cross (FlyLab: miniature, singed, tan) |
| · Gene order |
| · Genetic map |
| |
| 6. Dihybrid, trihibrid cross (mice) |
| · Autosomal dominant, autosomal recessive |
| · Genotypes |
| · Given map with three markers, predict number of F2 progeny |
