experiment was to determine what gene or genes are responsible for the white eye phenotype of two strains of Drosophila melanogaster. According the literature‚ the w+ gene is located on the X chromosome at 1.5 genetic map units (1). In addition‚ the st+ and bw+ genes are autosomal and assort independently‚ meaning they are two different genes located on two different chromosomes. It is stated that the bw+ gene is located on the 2R chromosome at 104.5 map units (2) and the st+ gene is located on the 3L chromosome

Genes are codes for certain function that are found in DNA. The combination of genes is what makes each individual unique. MCADD is a genetic disorder‚ caused by a mutation or damage to the gene‚ ACADM‚ that codes for the enzyme‚ medium chain acyl CoA dehydrogenase. This results in the enzyme being absent or existing in minimal quantities. An enzyme increases the rate of a chemical reaction. Our body needs many enzymes in order to make the materials needed for our bodies to function and be healthy

four daughter cells‚ each having one-half the normal number of chromosomes (23). Genes that code for a particular trait come in several forms or alleles. Genotype refers to the particular set of alleles an individual receives. Phenotype refers to an individual’s observable attributes. People with different genotypes may have similar phenotypes. Some traits involve only one gene locus and are called single-gene traits. The transmission of these traits from parent to offspring follows predictable

lay claim to individual genes in the human body‚ or is the practice of patenting genes a bad idea? In his work entitled “Patenting Life‚” famed author Michael Crichton uses several illustrations of why he believes the practice of issuing patents on human genes is not only a bad idea‚ but goes against common sense. Saying “you cannot patent snow‚ eagles‚ or gravity‚ and you shouldn’t be able to patent genes‚ either” (Crichton 442). Crichton compares “owning” a patent on a gene to some of the most majestic
