Honors Biology – Genetics Mixed Review Worksheet For each of the following: o Identify the genotypes of the parents o Complete a Punnett Square o Give the genotypic AND phenotypic results of the cross (percentage OR ratio) 1. In fruit flies‚ long wings are dominant to short wings. Complete a cross between a short winged male and a heterozygous female. 2. In certain flowers‚ blue and yellow flowers are incompletely dominant to each other. Show the cross

Lab 02-Mendelian Inheritance 1. Introduction The purpose of this lab is to learn how to use Mendel’s Laws of Inheritance to generate expected phenotypic ratios of F2 generation. In order to do this‚ we cross true-breeding parents to generate F1 generation and then inter-cross the F1 generation to yield F2 generation. Then‚ we test the efficiency of the expected phenotypic ratios generated by comparing them with the observed phenotypes of randomly selected F2 generation. 2. Methods • Perform a monohybrid

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
