Genetics & Drosophila Melanogaster Lab Report Background: For two months‚ you will breed Drosphila melanogaster (fruit flies) and set up genetic crosses in order to determine the pattern of inheritance of certain mutant traits. The traits for which we will examine the pattern of inheritance are apterous (wingless)‚ vestigial (crippled wings) or white eyes. These are all mutant strains. The normal condition (winged and red eyes) is referred to as the wild type strain. Objective: The intial

PROBABILITY and MENDELIAN GENETICS LAB Hypothesis: If we toss the coin(s) for many times‚ then we will have more chances to reach the prediction that we expect based on the principle of probability. Results: As for part 1: probability of the occurrence of a single event‚ the deviation of heads and tails of 20 tosses is zero‚ which means that the possibility of heads and tails is ten to ten‚ which means equally chances. The deviation of heads and tails of 30 tosses is 4‚ which means that the

Dihybrid Cross Worksheet 1. Set up a punnett square using the following information: • • • • • Dominate allele for tall plants = D Recessive allele for dwarf plants = d Dominate allele for purple flowers = W Recessive allele for white flowers = w Cross a homozygous dominate parent (DDWW) with a homozygous recessive parent (ddww) 2. Using the punnett square in question #1: a. What is the probability of producing tall plants with purple flowers? Possible genotype(s)? b. What is the probability of

Plants vs. Zombies: A Lesson on Artificial Selection and Classification Team Name: Team Members: Performance Task: There is a Zombie Apocalypse caused by a comet that traveled too close to the earth. People who were not sheltered during the comet’s passing were turned into zombies. It is believed that the comet was created by aliens to prepare our planet for invasion. Plants and Fungi were also affected by the comet and mutated and now carry many unusual traits. For some unknown reason these plants

According to the pedigree‚ is cystic fibrosis inherited as a dominant or as a recessive trait? Explain how you made your conclusion using evidence from the pedigree and the principles of genetics. -Cystic fibrosis is inherited as a recessive trait. Each child of 2 carriers has a ¼ chance of inheriting

Materials and Methods Section What came first was a bitter experience. We were given strips of PTC paper‚ so we could see if we tasted them. After spitting mine out‚ I knew right away I was a taster. Luckily for others‚ they weren’t tasters‚ and they didn’t get the thrill of having a bitter flavor enhance their mouths. What came next was swabbing our mouths. In order for us to get the DNA that we wanted to break down‚ we used the easiest supply of free DNA- our saliva. It was this saliva that was

Character Analysis: Gregor Samsa in “The Metamorphosis” by Franz Kafka “The Metamorphosis” by Franz Kafka is a novel in which Gregor Samsa is the main character. Gregor is also the protagonist in the story. “The Metamorphosis” is a depiction of Gregor’s life and how he transforms from a human into a bug. In the novel‚ it describes the journey and struggle he has been through. Most people don’t turn into bugs‚ but a lot of people may be able Gregor had many feelings towards life and how he viewed

INVESTIGATION OF THE INHERITANCE OF THE ROSETTE GENE IN BRASSICA RAPA By: Justine Poorbaugh Foundations of Biology 2 Laboratory Thursday 2:30 PM Professor Cheek April 21‚ 2011 ABSTRACT The Brassica rapa is a rapid growing plant that has a standard form and a mutant rosette form. Relative to normal plants‚ the rosette form is shorter and takes longer to flower. The mode of inheritance of the rosette gene was tested by crossing two true-breeding plants‚ one of each form. The F1 generation

Kayla Berezne Mrs. Cohen Honors Biology 24 March 2013 Genetic Predictions in the Fruit Fly The Drosophila melanogaster is a fruit fly with a very short life cycle. They can be winged or wingless‚ and have red eyes or white eyes. The different options are called alleles. Alleles are the variants of a specific gene‚ and one is received from each parent on each chromosome. (“What Are Dominant and Recessive?”). It was chosen to use winged females and wingless males to predict the offspring in this
