Genetics

Introduction At the year of 2000, the first designed baby was born. When the technology of designing babies was introduced, it became a controversial topic between people. Designer babies are those whose DNA has been altered to bring desired results in gender, appearance, intellectual, health, and more.(The Friendly Brain) Despite its advantages, critics have stated […]

The effects of chromosome activity upon the inherited traits of organisms have been formulated into a number of principles, or laws. Some of these principles were observed long before anything was known about chromosomes and genes. Gregor Mendel made the first scientific study of heredity and published his findings in 1866. Mendel’s method was to […]

One image can change one’s real-world perception, especially in science. From photographs of movement to microscopic images of atomic molecules, images are often used to spark public interest in science and engineering. For instance, the first X-ray taken by Wilhelm Conrad R?ntgen in 1895 would eventually transform medical science, allowing doctors to examine their patients’ […]

Case Analysis #1: DNA is the molecule of heredity             From Gregor Mendel’s theory of existence of gene and their transmission from generation to generation, to Friedrich Mischer discovery of DNA, the creation of Watson-Crick Model  leading to the advancement of genetic engineering, biotechnology and cloning. These are among the historical evidences that DNA is […]

A Murder and Possible Rape Case: Victim, young woman found in a foreclosed building. The victim was found lying on the floor, facing the ceiling, in between the couch and the dusty fireplace. There were no signs of serious injury; she had some bruising on her face and forearms, reddish colouration around her eyes (suspected […]

In this analysis review by Hendrik Emons, the new EU GMO rules are constantly being regulated and tested through investigations to determine their sustainability and reliability for farming in Europe. Further investigations are concerned with existing GMO rules, as suggestions for potential new rules for genome editing and new breeding techniques may arise. GMOs may […]

Several studies have been carried out particularly on polygenic traits that have different alternate forms for example, white flower color vs. purple flower color. However many traits are more multifaceted than this and can take on any number of incessant values. For instance in humans there are not just two groups of people i.e. tall […]

As William Penn says in his book, Some Fruits of Solitude, in Reflections and Maxims Relating to the Conduct of Human Life, “Men are generally more careful of the breed of their horses and dogs than of their children. ” This statement is true, to a point. While eugenical artificial selection could in fact ‘breed’ […]

Transferability of simple sequence repeat (SSR) markers developed in red clover (Trifolium pratense L.) to some Trifolium species Abstract Microsatellite markers previously developed for red clover (Trifolium pratense L.) were used in cross-amplification tests of eight other Trifolium species. Of the 20 SSR loci tested, 9 (47.37%) had positive results and were found to be transferable […]

The variability of a biological population is a result of the genetic make – up of the individuals in this population in relation to their respective environments. To begin an effective breeding program it is absolutely necessary to evaluate genetic variability with parameters such as genotypic coefficient of variation, heritability estimates and genetic advance. All […]
