Peditree: pedigree database analysis and visualization for breeding and science
1Laboratory of Plant Breeding, Wageningen University and Research Centre, P.O. Box 386, NL-6700 AJ Wageningen, The Netherlands.
Abstract:
At the Wageningen Laboratory of Plant Breeding, a software package has been developed to query a simple structured database with variety pedigree data. The package, called Peditree, creates a tree-shaped representation of pedigree information and has several visualization and lookup options. Estimates of inbreeding coefficient within a pedigree or coefficients of coancestry among pedigrees can be obtained. Furthermore trait data--if available--can be linked, displayed within the pedigree tree, and used to highlight pedigree entries that comply with set criteria.

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...
