The following three recessive genes are found in corn: bt1, brittle endosperm. g117 glossy leaf and rgdl, ragged seedling. A trihybrid of unknown origin is testcrossed producing the following offsprings:
Brittle, glossy, ragged 357 Brittle glossy 74 Ragged 66 Glossy 79 |
Wildtype 343 Brittle ragged 61 Glossy ragged 11 Brittle 9 |
What are the genotypes and phenotypes of the original parents?
Diagram the linkage relationship in the F1.
Determine the gene order.
Calculate the amount of recombination observed between the genes and diagram the gene map.
Is there any crossover interference? If yes, how much inference is operative?
