Drosophila melanogaster - Sex linkage and inheritance of genes through cross breeding Abstract This experiment looks at the relationship between genes‚ generations of a population and if genes are carried from one generation to another. By studying Drosophila melanogaster‚ starting with a parent group we crossed a variety of flies and observe the characteristics of the F1 generation. We then concluded that sex-linked genes and autosomal genes could indeed be traced through from the parent generation

A Study of Gene Mapping Using Tetrad Analysis in the Fungus Sordaira Fimicola BISC 302 Genetics Lab: Wednesday June 14 2006 ABSTRACT The fungus‚ Sordaria fimicola‚ selected for tetrad analysis due to its ease in observation of recombination events. These fungi have mutation in genes that control spore colour. Tetrad analysis can be conducted by crossing wild type spores with the two mutant types‚ tan and gray. Crossing wild type with the mutants can allow for direct observation of

Describe the process by which genes and environment operate together to influence development. Discuss the significance of these processes for our understanding of child development. This essay will give a detailed account of the process by which genes and the environment operate together to influence development. Looking at Physical development and Language development and the perspectives of Natavism‚ Behaviourism. Constructivism and Social Constructivism it will explain the role of these perspectives

I strongly believe that it was a combination of both nature and nurture‚ but if I had to choose one‚ I would have to say that the genes that came from my father have a big impact on this trait. My father is also a disorganized person. I am very much alike to him in this regard. On the other hand‚ my mother is extremely organized. She’s someone who tries to keep everything as organized

The technique of gene cloning has important applications in medicine‚ biotechnology‚ agriculture and research. Discuss two applications of this technique‚ which in your opinion‚ have had significant impact on society. Gene cloning is achieved by inserting a required gene into a vector DNA. This produces Recombinant DNA and when introduced to a host cell the vector is copied. It divides to produce lots of copies of the gene of interest (Willey‚ Sherwood and Woolverton‚ 2012). There are many applications

The word gene comes from the word for origin’ in Greek. Genes are sections of DNA that determine the structure of a protein. They are the foundation of all life on earth. They form and decide the characteristics of every living creature and the genes that exist today are there because they have been successfully reproduced in the past. The DNA that determines the person that we grow into is created from half of each of our parents DNA. In the process of evolution certain genes have been eradicated

article‚ “Elephant Genes Hold Cancer-Fighting Secret‚” the author‚ Laura Geggel‚ explains how researchers have recently discovered that cancer is less common in elephants than in humans because they have more copies of a gene that stops tumor growth. Researchers that understand how this gene has evolved and why it works to stop cancer growth in elephants may be able help find ways to treat or cure cancer in humans. Researchers conducted a study that focused mainly on the TP53 gene‚ which normally codes

Longevity pathways converge on autophagy genes to regulate life span in Caenorhabditis elegans Autophagy‚ translated from Greek means to ‘self eat’. It is a basic catabolic mechanism involving cell degradation of unwanted or dysfunctional cellular components through the lysosome. Autophagy has been speculated to alter lifespan in organisms. Autophagy is triggered in response to varied stress and physiological conditions like food deficit‚ hyperthermia‚ etc. At molecular level‚ an autophagy pathway
