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

regards heredity and states‚ “two alleles for each trait separate (segregate) during gamete formation‚ and then unite at random‚ one from each parent‚ at fertilization. This is deemed the law of segregation. To go along with this general rule of thumb‚ Mendel also considered the potential for shuffling of genes during di-hybrid crosses. When there are two individual genes in play‚ their inheritance pattern act completely independent from one another. Thus‚ “during gamete formation‚ different pairs of alleles

Ebbinghaus became the first psychologist to investigate learning and memory experimentally. In doing so‚ he not only showed that Wundt was wrong on that point but also changed the way in which association‚ or learning‚ could be studied. His goal was nothing less than to apply the experimental method to the higher mental processes. Most likely influenced by the popularity of the work of the British associationists‚ Ebbinghaus chose to under- take his breakthrough research in the area of human

Introduction: The study of genes‚ Genetics‚ is a branch in Medicine that studies how genes are formed‚ distributed and how they change the organisms’ characteristics. The pioneer in the field of Genetics‚ Mendel‚ was able to formulate various laws based on genes‚ such as the law of segregation. Even though Mendel did not know about the existence of DNA‚ he was able to show that some traits are carried to offspring‚ even though the parents did not appear to have the gene. There are two types of genes‚ the

behavior of matter. He proclaimed that living and non-living matter all obey the same laws as physics and chemistry‚ and proposed that living organisms should be treated in terms of molecular and atomic structure. 1865 Gregor Mendel discovered the basic laws of heredity‚ and first used the word “gene.” He deuced that genes come in pairs and are inherited as distinct units‚ one from each parent. He also tracked the segregation of parental genes and their appearance in
