Abstract:
Two pollen diagrams from within one metre of each other at a blanket peat site on the North York Moors are similar, and fully justify the usual practice of preparing only one diagram. There are however minor differences. These indicate the degree of random variation that can occur and should be borne in mind when interpreting pollen diagrams from blanket peat.

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...
