Sample text

Mendel was very observant, and was a good botanist. 4. Traits of the pea plant used by Mendel to discover the genetic laws of segregation and independent assortment. Each trait had two phenotypes: one controlled by a dominant allele and one by a recessive allele. 2. MENDELIAN GENETICS 27 genetics much simpler than would be the case if he’d picked plants that were normally (or even partially) outcrossers. He used plant lines that would only generate plants of a single type when the plants were allowed to self-fertilize.

2c). The different versions of each gene are called alleles, and differ from one another in the sequence of DNA at that chromosomal locus. Mendelian traits are also characterized by discrete variation, where the different phenotypes of the trait can be broken into obvious categories. In the example of pea plant height, tall versus short plant type is determined by the genotype at a single genetic locus that controls height. As you will see throughout this book, most traits are more complex than Mendelian traits because they are controlled by the gene products of many genes, and hence are called polygenic traits.

HOW THE ADOPTION OF PLANT BIOTECHNOLOGY HAS IMPACTED THE ENVIRONMENT The two key aspects of environmental impact of biotech crops examined below are decreased insecticide and herbicide use, and the impact on carbon emissions and soil conservation. 4. 1. Environmental Impacts from Changes in Insecticide and Herbicide Use Usually, changes in pesticide use with GM crops have traditionally been presented in terms of the volume (quantity) of pesticide applied. While comparisons of total pesticide volume used in GM and non-GM crop production systems can be a useful indicator of environmental impacts, it is an imperfect measure because it does not account for differences in the specific pest control programs used in GM and non-GM cropping systems.
