Abstract:
The inheritance of the dehiscent pod character was investigated in two recombinant inbred populations using a simplified correlation analysis. The approach identified three regions on the pea genome that affect the expression of pod dehiscence. The region on linkage group III corresponded to the expected position of Dpo, a gene known to influence pod dehiscence. A locus on linkage group V appeared to have a slightly smaller effect on expression of the phenotype. The third region was observed only in one cross, had a greater effect than Dpo, and was postulated to be yellow pod allele at the Gp locus

Trihybrid Crosses
Some of Mendel’s crosses examined three pairs of contrasting characteristics. Such a cross is called a trihybrid cross. A trihybrid cross is a combination of three individual monohybrid crosses. For example, plant height (tall vs. short), seed shape (round vs. wrinkled), and seed color (yellow vs. green).
The F1 generation plants of a trihybrid cross are heterozygous for all three traits and produce eight gametes. Upon self-fertilization, these gametes have an equal chance to...
