The environment offers essential resources‚ like nutrients that are recycled to keep soil fertile‚ biological services‚ such as providing the global pollination of crops that we depend on for food‚ and natural improvements for our quality of life‚ such as controlling the chemistry of the atmosphere. These resources are vital to the survival of the human race‚ and are often taken for granted. Humans are constantly using these products and amenities to assist in their lives and consequently creating

INVESTIGATION OF THE INHERITANCE OF THE ROSETTE GENE IN BRASSICA RAPA By: Justine Poorbaugh Foundations of Biology 2 Laboratory Thursday 2:30 PM Professor Cheek April 21‚ 2011 ABSTRACT The Brassica rapa is a rapid growing plant that has a standard form and a mutant rosette form. Relative to normal plants‚ the rosette form is shorter and takes longer to flower. The mode of inheritance of the rosette gene was tested by crossing two true-breeding plants‚ one of each form. The F1 generation

However‚ others believe that this kind of genetic engineering cannot be justified because GM crops threaten the environment and may cause havoc through cross-pollination. They could have as yet unknown effects on human health by causing unexpected allergic reactions and transferring antibiotic resistance markers. A potentially more serious criticism is that it leads to the exploitation of developing countries: many

Inheritance System of anthocyanin pigments in Brassica rapa. Introduction The observations of Brassica rapa in class revealed a variation in color. Brassica rapa‚ also called fast plants‚ was studied because as their name suggests‚ they are able to complete a lifecycle in a short period of time. (www.fastplants.org) The color variations we observed among the plants were that some had green stalks while others were purple. The pigment which gives plants their color is called anthocyanin.
