Genetic Diversity In Agriculture Genetic variation is the raw material for the plant breeder‚ who must often select from primitive and wild plants‚ including wild species‚ in search of new genes. The appearance of new diseases‚ new pests‚ or new virulent forms of disease causing organisms makes it imperative that the plant be preserved‚ because it offers a potential for the presence of disease resistant genes not present in cultivated varieties. Also‚ there are demands for new characters-- for

understand the genetic argument that homosexuality is inborn‚ it is imperative to understand the basic concepts of behavioral genetics. Behavioral genetics‚ as stated by Baker – a scientific journalist for the [National Association for Research and Therapy of Homosexuality] otherwise known as NARTH‚ is the study of genetic influences on human behavior. Basically it is the study of genes‚ operating within the environment. There are basically three kinds of inquiries to demonstrate the genetic basis for

Discuss genetic explanations for aggression. Early research concentrated on chromosomal abnormalities but no specific genotype has been associated with aggression. Genes determine how much testosterone a person’s body produces and how quickly it circulates around their body. Genes also determine the synthesis of testosterone receptors‚ and how many and how sensitive such receptors are. The gene called monoamine oxidase A (MAOA) produces an enzyme which regulates the metabolism of serotonin in

is currently a substantial body of research supporting the argument that there is a genetic influence on numerous human behaviors‚ such as homosexuality‚ intelligence and personality. One indication that behavior has a genetic basis is that behavior is often species specific. Examples include the warning behavior of prairie dogs or the mouth to mouth sharing of blood amongst vampire bats. The closer our genetic resemblance is to a certain species‚ the more behaviors we have in common. Since long

Human Genetic Engineering Human Genetic Engineering is the alteration of genetic material. As science is improving as so does our need to make the world a “better” place. Technological advancements have let us cloned many animals but the next step you say? The next step is human engineering‚ as humans of perfection; we are always trying to find ways to make things better than others. They are able to manipulate the human genome and to cure the world of diseases. Scientists are able to make the

Is anti-social behaviour a result of genetic inheritance or your environment and upbringing? The debate of the cause of anti-social behaviour has been ongoing for many years between scientist’s‚ professionals and the general public. Experts disagree over whether genetics‚ environment or home life plays the greater role in anti-social behaviour. The general opinion over all of why people turn to violence and anti-social behaviour focuses on family breakdown‚ drug and alcohol abuse‚ poverty‚ unemployment

9.7 Option – Genetics: The Code Broken? Contextual Outline Science has come a long way since Mendel’s important work on identifying the transmission of inherited factors across generations. The code for transmitting this genetic information has been identified and models have been developed to explain gene functioning. Transcription of the information into functional proteins is now well understood and models are being developed to test how genes direct the structure‚ function and development
