[Application of RAPD in the taxonomy of the genus Fritillaria]
Objective:
To provide the molecular data for the right application of the Chinese medicine "Beimu".
Method:
Using the technology of RAPD, we studied the relationship among 12 samples of Beimu.
Result:
The total genomic DNA of all the samples are about 21 Kb in size. Among 20 primers used, the five primers can reatedly generate a certain specified amplified band type, 27 bands were recored from all amplified products and 25 polymorphic fragments were found in it. The size of amplified fragments is between 450 bp and 1904 bp.
Conclusion:
The similarity within species is higher than those between species. The relationship of Fritillaria anhuiensis and F. puqiensis is the farest, while F. thunbergii and F. puqiensis is the closest.

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...
