A Summary of Alkaptonuria Alkaptonuria is an inborn error of metabolism that presents most notably with the occurrence of black urine when the urine is exposed to air. For this reason‚ it is also called the “Black Urine” disease. It is an autosomal recessive disorder and is therefore inherited genetically. Alkaptonuria is very rare‚ with a presentation of about 1:250‚000(ref1). The causality behind Alkaptonuria is a deficiency in homogentisic acid 1‚2 dioxygenase‚ an enzyme that is found in the

Drosophila melanogaster are a species more commonly known to us as fruit flies. They are extremely important in biological research due to the fact that they make excellent model organisms for understanding genetics. Reasons behind their frequent use include; easily cultured in the lab‚ short generation time‚ and they can produce many offspring. In this lab report‚ we began with three different strains of Drosophila. Introduction The common form of Drosophila is known as the “wild type”‚ any fly

Question: If I cross a female apterous fly with a male wild fly‚ what would the offspring look like? Hypothesis: If I cross a female apterous fly with a male wild fly‚ then the offspring will be a 50% chance of a apterous fly or 50% chance of a wild fly. If I cross a female apterous fly with a male wild fly‚ then the offspring will be a 100% wild fly. Supporting Evidence for Hypothesis: Apterous flies have no wings‚ and are a recessive gene‚ while wild flies have wings and are a dominant gene
