Heredity and Hormones and How They influence Behavior There are many things that are unknown about the reasons behind people’s thoughts and actions‚ but in recent years‚ concepts about how a person’s own genetic make-up and hormones can affect our own behavior. Although there have been no breakthroughs that can definitively say this hormone causes people to act one way all the time‚ there have been instances where a person’s genetics and hormones can contribute to certain behavioral ideas. There

MENDEL`S PRINCIPLES OF GENETICS 1.0 INTRODUCTION: 1.1 BACKGROUND Gregor Mendel‚ who is now considered as founder of classical genetics‚ ( Elrod S. & Stansfield w‚2010)‚ conducted a series of experiments using garden pea plants‚ his aim was to find a way of explaining to his fellow scientists who believed the blending theory which had been proposed earlier by Wiseman‚ that heredity involved the interaction of discrete separable factors (now known as genes) After a statistical analysis of the

GENETIC TESTING Genes‚ the chemical messages of heredity‚ represent a blueprint of our possibilities and limitations. The legacy of generations of ancestors‚ our genes carry the key to our similarities and our uniqueness. When genes are working properly‚ our bodies develop and function smoothly. But should a single gene or even a tiny segment of a single gene go askew‚ the consequences can lead to deformities and disease‚ even death. In the past 20 years‚ amazing new techniques have allowed

Technologies and resources generated by the human genome project and other genomics research are already having a major impact on research across the life sciences. By genetic science the legislators and judges easily understand criminal behavior. They also predict that for what reason the guilty person has occurred such occurrences. Genetic tests will flood the courtroom with evidence purporting

Mendelian Genetics * Pea plants have several advantages for genetics. * Pea plants are available in many varieties with distinct heritable features (characters) with different variants (traits). * Another advantage of peas is that Mendel had strict control over which plants mated with which. * Each pea plant has male (stamens) and female (carpal) sexual organs. * In nature‚ pea plants typically self-fertilize‚ fertilizing ova with their own sperm.
