and characteristics which in the case of humans, derive theirs’ from their common ancestors. However these characteristics are similar but their genetic composition vary in one way or the other. For instance, the early day human, from whom all humans of the present day derived their characteristics, looked alike in genetical formation. The degree of genetic variation has significantly increased over the years to include blacks, Whites, Latinos and many others, thanks to reproduction. The increase in

results in greater degree of variation. Two parents give rise to offspring that have unique combinations of genes inherited from two parents. Sexual reproduction generates genetic variation by homologous parings (half of the chromosomes form the mother and half from the father). The process crossing over is the exchange of genetic material which enhances variation in a species; it produces recombinant chromosomes, which combine genes inherited from two parents. Crossing over occurs early in meiosis

Cystic fibrosis is on of the leading autosomal recessive diseases affecting people worldwide. It generally affects people of European decent more than those from descendants of other countries. Cystic fibrosis has a wide range of phenotypes, and it also can effect several different organ systems, including respiratory, gastrointestinal, and even the reproductive system. The disease is usually fatal, although the average life expectancy is about 40 years old. The mutation effects the regulation of

According to Declarations de Berne (n.d.) the general views against the patent are as follow: - There is a negative impact on innovation as breeders are not allowed to use the patented plants, animals or genetic material freely for further breeding. - Patents have been the engine behind tremendous market concentration in the seed sector, destroying competition and forcing small and medium enterprises out of the market. - Patents lead to higher

INTRO In 1963 Sydney Brenner age 36, introduced Caenorhabditis elegans (C. elegans) as a model organism for developmental biology and the study of the nervous system. A model organism is an animal model with certain characteristics that make it easy to use. Dr. Brenner found that C. elegans meets a certain set of criteria that make it a model organism. Such as having a rapid life cycle, a simple reproductive cycle, and small in size and easily observed phenotypic characteristics. Within three years

[pic] Moral and Ethical Issues in Gene Therapy • Dr • [pic] Introduction Genetic research has advanced in a dramatic fashion in the last decade or so, to the point where it has now become possible to attempt therapeutic genetic modification, in a few cases of human genes, where a defects exists which manifests itself in certain serious diseases. This possibility, known as gene therapy, is only in its infancy. At present, no one knows how effective it will prove to be, even

organism, however primitive. For example, the smallest genetic organism known to exist is the Mycoplasma genitalium (a bacterium that lives in the urinary and genital tracts of humans), which has around 500 genes. Scientists have attempted to remove the genes (the genetic material) from this organism to see at what point it could no longer function, i.e. at what point it ceases to be and dies. This would give them an idea of the minimum amount of genetic material required for life. They concluded that they
