The X/Y sex chromosomes and the 2‚3‚4‚ autosomes. It is important to know the differences between the two adult sexes in order to record and collect the data accurately. The major sexual differences in Drosophila are apparent in the abdominal segment of the flies. In males‚ the last abdominal segment of the male is much larger and rounded than that in the female. Another indicator is the presence of sex combs present in males. Male flies has a small‚ densely

Madison Fowler Fruit Fly Genetics: Dihybrid Cross Abstract Vestigial and ebony are two commonly studied mutations in fruit flies. Studies of these mutations have even been correlated with reproduction. In this study‚ a dihybrid cross is conducted between heterozygous vestigial and ebony flies in order to determine the acceptance of the nine to three to three to one ratio. If the results of this experiment come out as what is expected‚ about nineteen percent of the filial two generation should

2/2/15 Block 1 Introduction and Background Drosophila melanogaster or more commonly referred to as “fruit flies” have been used for genetic research for over 100 years. During his time at Harvard university‚ Charles W. Woodworth is credited with being the first to suggest fruit flies be used for genetic research. A century later‚ fruit flies are the most widely used eukaryotic organism for genetic research (Drosophila). Their ease of use and rapid rate of reproduction has allowed

Introduction Drosophila melanogaster is a common fruit fly that has been useful for most experiments in the study of Genetics. The male and the female fruit fly are similar and different in regards to how they look‚ structurally. They are similar because both genders have a head‚ thorax‚ proboscis‚ antennae‚ eyes‚ and mouth parts. However‚ males are smaller than females and have about five abdominal segments as opposed to the seven that the female has. The life cycle of these fruit flies consist

saliva or medicine to stimulate the salivary glands is sometimes used. What are the salivary glands? The salivary glands make spit (saliva). Saliva is important in the breaking down of the food that you eat. It makes food moist‚ lubricating it as it passes from the mouth to the gullet. It also contains enzymes in the saliva which break down some of the starch and fat in your food. [pic] There are three pairs of glands that make saliva. From these glands‚ saliva drains into the mouth down short
