Biology Exam 2013 - Review UNIT: PATERNS OF INHERITENCE Describe Mendel’s experiments: * Chose a female parent; chooses a male parent; pollen is collected from the stamens and dusted onto the female parent stigma; pollen fertilizes the eggs. The ovary develops into the pod and eggs develop into the peas; when peas are planted they develop into pea plants. Why Pea Plants? * Easily obtained * Grown quickly; several generation of peas can be observed * Traits are easily visible

Mediterranean Scrub Introduction: Regions of Mediterranean-type climate occur roughly between 30° and 40° latitude on the west coasts of continents‚ where offshore there are cold ocean currents. Each region in which the Mediterranean shrublands and woodlands occur is island-like in character and thus there is frequently a high degree of endemism. Comparative studies of the several regional expressions of this biome reveal interesting examples of convergent evolution in plant families and birds (but
