- Father of Genetics. Gregor Mendel, through his work on pea plants, discovered the fundamental laws of inheritance. He deduced that genes come in pairs and are inherited as distinct units, one from each parent. Mendel tracked the segregation of parental genes and their appearance in the offspring as dominant or recessive traits.

THE GENETIC BASIS OF INTELLIGENCE The study of intelligence genetics examines how much and by what manner mental abilities are affected by genes. Since many genetic and environmental factors influence intelligence, it is considered a complex trait.However, we do not know much about the quantity and character of genes responsible for mental abilities.n most genetic studies, researchers lump the different subcategories of intelligence into Intelligence Quotient (IQ), a single scale used to quantify intelligence. The concept of IQ was first developed by Alfred Binet, a French psychologist and lawyer, in 1905.

1. INTRODUCTION (GENES, CHROMOSOMES, AND DNA) 1924: Microscopic studies show that DNA is present in chromosomes. 1952: Biologists Hershey and Chase realize that it is DNA that encodes the genes. The gene is determined by the values of the DNA base pairs in the gene.

- These discoveries were an important foundation for the later description of DNA. In the early 1950s, the race to discover DNA was on. At Cambridge University, graduate student Francis Crick and research fellow James Watson (b. 1928) had become interested, impressed especially by Pauling's work. Meanwhile at King's College in London, Maurice Wilkins (b. 1916) and Rosalind Franklin were also studying DNA.

- Gregor Mendel was a monk and a teacher. He discovered genetics. He used pea plants to represent the 1 to 2 to 1 ratio. He mixed green and yellow peas seeds, and found out (aft … er many tries) that the characteristics of two different peas would grow a new pea.regor Mendel was a little-known monk in central Europe, later becoming 'the father of genetics' by studying dominant and recessive traits in reproduced pea plants, therefore … discovering that some of the parents' traits rule over the other, and so on.

INTRODUCTION TO GENETICS The Monk and his peas | Back to Top. An Austrian monk, Gregor Mendel, developed the fundamental principles that would become the modern science of genetics. Mendel demonstrated that heritable properties are parceled out in discrete units, independently inherited. These eventually were termed genes.

Genetics Genetics is the study of genes, genetic variation, and heredity in living organisms. It is generally considered a field of biology, but intersects frequently with many other life sciences and is strongly linked with the study of information systems. The father of genetics is Gregor Mendel, a late 19th-century scientist and Augustinian friar.

Gregor Mendel: Great Minds What did Mendel teach us about heredity? Gregor Mendel, known as the father of modern genetics, was born in Austria in 1822. A monk, Mendel discovered the basic principles of heredity through experiments in his monastery's garden. His experiments showed that the inheritance of certain traits in pea plants follows particular patterns, subsequently becoming the foundation of modern genetics and leading to the study of heredity.

genetics Genetics is the study of the traits people and other animals inherit from their family through DNA. Compare the size of your nose to your father's and you are dealing with genetics — but only if he's your biological father. Genetics involves studying genes — DNA — to look at how organisms evolve and are related. Scientists use genetics to prove whether genes for things like depression or intelligence exist.

How Did the Discovery of DNA Impact the Scientific Community? The discovery of DNA focused scientists' efforts and led to the research into genetics and heredity aimed at improving life on Earth today. Identification of DNA DNA's discovery can be traced to 1868, when Swiss medical student Johann Friedrich Miescher began work on isolating proteins from white blood cells.

Introduction The Age of Genetics Gregor Mendel performed a series of experiments on garden peas in the mid–nineteenth century. His findings laid the foundation for the study of genetics. The Discovery of DNA By then, chemists and biologists had come to a much more detailed understanding of the structure of cells, the building blocks of all living organisms, than existed in Mendel's day.

Who discovered Hemophilia? The blood of a person suffering from hemophilia doesn’t coagulate easily or quickly. This genetic disorder was first discovered in 1803 by Philadelphian physician, Dr. John Conrad Otto. He verified that the disorder was hereditary and it affected males more as compared to females.

DNA on Parade New techniques are allowing the imaging of DNA with conventional optical microscopes as well, he said, but they are in their infancy. Chromosomes, the spiraling strands of DNA that package the series of chemical bits called genes, are easily visible through a strong enough microscope if the right stain is used.In fact, the development in the 19th century of aniline dyes that make the chromosomes stand out led to their discovery.ew techniques are allowing the imaging of DNA with conventional optical microscopes as well, he said, but they are in their infancy.

Genes and Genetic Inheritance Definition: Genes are segments of DNA located on chromosomes. Genes exist in alternative forms called alleles. Alleles determine distinct traits that can be passed on from parents to offspring.The process by which genes are transmitted was discovered by Gregor Mendel and formulated in what is known as Mendel's law of segregation.lleles determine distinct traits that can be passed on from parents to offspring.

Genetics The molecular basis for genes is deoxyribonucleic acid (DNA). DNA is composed of a chain of nucleotides, of which there are four types: adenine (A), cytosine (C), guanine (G), and thymine (T).he father of genetics is Gregor Mendel, a late 19th-century scientist and Augustinian friar. Mendel studied 'trait inheritance', patterns in the way traits were handed down from parents to offspring.

History of genetics The history of genetics dates from the classical era with contributions by Hippocrates, Aristotle and Epicurus. Modern genetics began with the work of the Augustinian friar Gregor Johann Mendel. His work on pea plants, published in 1866, described what came to be known as Mendelian inheritance. Many theories of heredity proliferated in the centuries before and for several decades after Mendel's work. The year 1900 marked the rediscovery of Mendel by Hugo de Vries, Carl Correns and Erich von Ts

Introduction The Age of Genetics Early History of Genetics. Genetics is a relatively new science. It rests on two lines of research. The first is the discovery, made in the mid–nineteenth century, of how traits or characteristics (eye color or the susceptibility to a certain disease, for example) are passed from one generation of an organism to another.
