Introduction When analyzing biological processes and development, Drosophila melanogaster is an ideal organism to utilize. Compared to other organisms, the functions of D. melanogaster are easier to manipulate due to its quick sedation time from carbon dioxide. These flies can be sedated in less than ten seconds with a carbon dioxide flow rate of 5L/min. D. melanogaster also produces offspring in a short amount of time (roughly 10 days at 25 degrees Celsius), which makes it a desirable species…

the PD (parental ditype) and NPD (non-parental ditype) asci along with the segregation independently, should be equal. The second hypothesis is for linked genes and this is that both of the spore coloration are seen on the same pair of homologous chromosomes. This just makes them inherited together due to the linkage physically together. The rule states that Mendel’s law doesn’t correspond with this and it would not make sense if the genes were linked. If the genes were linked then the PD and T…

creates four daughter cells that have only half of the amount of chromosomes that are contained within a human body, 23 instead of 46. Within the book it explains that meiosis goes through Interphase, Prophase, Metaphase, Anaphase, Telophase and finally Cytokinesis (a separate process) twice, to create all four of the daughter cells. Interphase is the life of the cell before it divides. Prophase is when the DNA condenses into Chromosomes, the…

JD’s Therapeutic Riding Ax Plan 1. Life story over JD: JD is an eight-year-old boy, who turns nine on Oct 26, who has been riding for a total of 12, 6 sessions with Kandy and 6 with Bowen. JD was adopted by his family when he was only 4 days old. JD is homeschooled by his mother and lives his parents. He has two siblings, a 12-year-old brother and 7-year-old sister, who are very helpful with JD. JD has a wonderful family, who is his main support system and helps when needed. JD’s mother…

formula was used: Cross Over= (B+C)/(A+B+C) Therefore, the cross-over frequency is found by adding the total number of recombinant asci and dividing that by the total number of asci. In order to calculate map distance, which is the distance the chromosome is from the centromere, the following formula was used: Map Distance= (% Crossed Over)/2 The percentage of cross-over must be divided by two because mitosis occurred, duplicating the cells. Therefore, only half of the spores are from…

In the movie Spiderman, the protagonist Peter Parker is a geeky, introverted, intelligent high school boy who gets bit by an engineered spider during a field trip to a lab. After the biting of the spider, Parker turns into a stronger and confident person who possesses spider-like qualities. Throughout the movie it is clear Spiderman’s legacy is that he wishes to protect civilians, he can be considered as a superhero vigilante or be considered as a criminal. Parker develops super speed, strength,…

While in the Meiosis there takes cell div ision two times but chromosomes divides only single time. 2) Mitosis usually occurs in the somatic cells. While Meiosis takes place in the germ cells. 3) Mitosis generally takes place in both sexually and asexually reproducing organisms. While we should know that Meiosis only…

The chromosomes condense and become so compact that they are able to be seen with light microscope. This marks the beginning of prophase. Each chromosome contains two identical copies called sister chromatids. The sister chromatids are attached at a central point called a centromere. The second key event in prophase is the assembly…

Section 1 The genetic disorder Cri Du Chat stems from the deletion of a portion the p arm of chromosome 5 in the affected person. This deletion is seemingly spontaneous in most affected individuals. “Approximately 90% of cases results from a sporadic, or randomly-occurring, de novo deletion” (6. pg. 606). This deletion may include a fraction to the entire loss of the p arm of the fifth chromosome as a whole. Taking into consideration the very spontaneous nature of this disorder, at…

of one or more modifier genes, for example the genetic background, the example of this is the complete baldness gene to the brown hair gene. Sex-linkage Sex linkage is the phenotypic manifestation of an allele which is connected to the sex chromosome of an individual, examples of this include the genes that control colour blindness and the male pattern baldness Sex-influenced effects Sex influenced effects are traits that are influenced by sex, for example if a male has one recessive…
