In 1831‚ Charles Darwin‚ proposed a theory of evolution occurring by the process of natural selection. This has come to be known as the Theory of Natural Selection. Darwin worked on his theory for 20 years and after learning that Alfred Russel Wallace‚ another naturalist‚ had developed similar ideas‚ the two made a joint announcement of their discovery in 1858. Darwin published ’On the Origin of Species by Means of Natural Selection’ in 1859‚ 28 years after he proposed his theory of natural selection

disease is first attributed to genetic causes ("inborn errors of metabolism"). (Sir Archibald Garrod‚ alkaptonuria) 1902 The chromosome theory of heredity is proposed by Sutton. Boveri recognizes that individual chromosomes are different from one another‚ but he doesn’t make a connection to Mendelian principles. Nevertheless‚ Boveri is given co-credit by friend E.B. Wilson (Sutton’s supervisor) for proposing the chromosome theory of inheritance. 1905 The word "genetics" is coined by William Bateson

Chapter 10 Foundations of Genetics Lecture Notes 1 Foundations of Genetics Mendel and the Garden pea The father of modern Genetics is Gregor Mendel. Gregor Mendel (1822-1884) was an Austrian monk who lived in a monastery where the experiments with the garden pea were performed. Mendel’s work with the garden pea was the fundamental study which unveiled the laws that govern genetics and heredity. Mendel was the first to use the scientific method in a very systematic and analysed his results

1. Genetic cloning is one way of studying the specific proteins involved in cell division. A gene contains the instructions for how to make a protein. By mutating a gene‚ the protein’s shape‚ size and function could all be affected. Mutating a gene changes its instructions. Once a mutated gene is created and incorporated into a cell’s DNA‚ the cell replicates‚ creating many cells containing the mutant gene. The cells with the changed gene can then be compared to normal cells. For starters‚ you must

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.

Albinism Background Information Albinism is a genetic disorder which affects the amount of melanin produced‚ in a person’s skin‚ hair‚ or eyes. Oculocutaneous albinism‚ Ocular albinism‚ and Hermansky-Pudlak syndrome are other names for this genetic disorder. The disorder affects mostly men‚ because it is a recessive gene. Females are usually carriers. Albinism does not affect any specific ethnic or religious group. Symptoms/ Effects This Genetic Disorder affects the eyes‚ skin‚ or hair’s pigmentation

Diet and Cancer There are endless hypotheses to why cancer occurs‚ some are true‚ but many are false. Diet most definitely plays a large role in the development of cancer. The main cancers that diet has an effect on are breast cancer‚ colon cancer‚ prostate cancer‚ liver cancer‚ stomach cancer‚ and esophageal cancer. There are a variety of reasons that diet can either cause or reduce an individuals risk for cancer development. As stated by the American Cancer Society‚ “Cancer is caused by changes
