Abstract:
Genomic DNAs of 37 cultivars of yellow peach (Amgdalus persica) were amplified by RAPD (Randomly Amplified Polymorphic DNA) with 22 primers selected from 200 arbitrary 10 decamer primers. Phylogenetic relationship was analyzed through cluster of bands in 180 amplified sites. Molecular checking index and conservation of key germplasm were put forward according to special bands.

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...
