Introduction Using Drosophila, the goal of this lab was to study and identify the genetics behind certain traits through to use of dihybrid crosses. With the crosses, the purpose was to find the different dominant and recessive traits in the eyes and wings of the Drosophila. Flies were used to study the genetics as opposed to other insects or animals because they are easy to mass-produce and the traits, when viewed under a microscope, are easily identifiable. The hypothesis was that the traits…

of southern California and at high altitudes in central Mexico. The beginning in their life cycle is egg, larval, chrysalis, and adult. First is a greenish egg attached to the underside of a milkweed leaf. Second is a worm like larva hatched from the egg. Third is the larva searching for a suitable place to weave into a chrysalis. Lastly turns into an adult monarch after 28 to 38 days. A few hours later, they fly off to migrate; however, the limiting factors that might affect their survival is…

males, the bottom half of the abdomen is black, while on the female, each segment of the abdomen is striped black. Drosophila have four main stages to their life cycle. These include: egg, larva, pupa and adult. The eggs small and translucent eggs take about one day to hatch after they have been laid. Next larva are formed. Larvae crawl through the food, eating and growing as they go, and later go through three molts only to climb up and glue themselves on the side of the vile after about 4 days…

reading passage and says that the reasons are inadequate. He also refutes each of the author’s reasons. First of all, the reading passage claims that the decline of the cedar trees is due to the infestation with the cedar bark beetle, since the larva can eat the tree wood. However, the professor counters this and explains that the beetle can’t infest the healthy tree. The healthy trees have powerful chemicals, which can harm the insects. Moreover, the professor points out that the beetles…

Sea Walnut, Rippenqualle (German) Venus' girdle, warty comb jelly, these are just some of the names for the Comb Jelly. This animal is “any member of a common genus (Mnemiopsis) of gelatinous, planktonic marine invertebrates of the order Lobata (class Tentaculata, phylum Ctenophora).” (""sea Walnut"." Encyclopædia Britannica.) Because of its pronounced abundance in estuaries in the heavily populated parts of the US and its precarious population growth after the 1980s, the Mnemiopsis Leidyi or…

Introduction Fruit fly Drosophila melanogaster that is used as a model to study genetics for more than a hundred years. Thomas Hunt Morgan, in the early 1900’s, used the heritable traits of a common species of fruit fly to develop our understanding of genetics. Morgan was the first to show through experiments that genes were located on chromosomes. He also found that certain fruit fly traits like eye color are found on the same chromosomes that also determine their sex. Fruit flies have several…

There are many important philosophical concepts that we have learned this year. The one that I have chosen to focus on is the idea of niche construction and evolutionary developmental biology, and relate it to different forms of causation. The article that I used as my focus is “EvoDevo and Niche Construction: Building Bridges” by Laland, Odling-Smee, and Gilbert. In this article, both niche construction and evolutionary developmental biology are talked about. The main claim is that both of…

scutellar bristles, orbital bristles, and ocellar bristles are all affected by this mutation. This mutation affects the phenotype equally in both female and male mutants. However, the mortality rate in hot cheeto females was greater than males. The larva of both the wild type and the mutant…

improvisational theater that was played. Some venetian carnival masks got their names from the characters in the plays that wore these masks. The type of mask I planned to make and wear if I was attending Capulet’s party is a Volto mask. Volto or Larva meaning mask or ghost in Latin, is a type of mask worn by commoners during holidays such as St. Marco’s Day.…
