This preview shows page 1 - 4 out of 9 pages. Count the number of purple and yellow kernels in five of the rows on your ear of corn and record the number on the chart. In order to conduct this experimental, Mendel’s laws of inheritance were to be studied in order to understand genetics. Theoretical: We will use a Punnett square to examine the theoretical outcome of possible monohybrid crosses. Now look at a cross between a Homozygous dominant parent (PP), and a Heterozygous parent (Pp). 3. Dihybrid Cross 5. Gametes are haploid, thus a gamete has only one gene for a single trait. ... Students will gather data on two monohybrid crosses: purple crossed with yellow, and the resulting F 1 crossed with F 1 corn. In other words, an, offspring receives a pair of alleles for trait; one allele per trait from each parent. are sex cells. https://masonadams18.blogspot.com/2015/02/corn-lab-report.html Bio I Lab - Mendelian Genetics in Corn - Lab Report.docx ... Monohybrid Cross in Corn INTRODUCTION: A cross between individuals that involves one pair of contrasting traits is called a monohybrid cross. A large ear of corn has a total of 433 grains, including 271 Purple & starchy, 73 Purple & sweet, 63 Yellow & starchy, and 26 Yellow & sweet Place the allele donated by each parent in the corresponding box. Label the Punnett squares as null hypothesis number one and number two. One, gamete contains one allele, while the other gamete contains the other. The purple and yellow kernels were counted as well as the, wrinkled and round for the monohybrid cross. Results for genetic crosses are often recorded as ratios. To find the percent of purple, divide the total purple by the total for all kernels, then multiply by 100. The, chromosomes formed are a result of random sorting from all possible combinations form both, the mother and father’s chromosomes. So, the corn that comes to mind for most of us - sweet corn - is a mutant two ways - homozygous recessive for both color (pp) and shape (susu)! P1 C/C × c/c F1 C/c heterozygous Red F1 cross C/c × C/c F2 C/C C/c c/c phenotypes Red, White in a phenotype ratio of 3:1 Transposable Elements Fill-in as before. 10-1 However, we’re going to look at the light side: biology jokes! That could be painful. Monohybrid cross. Mendel’s Law of Segregation states that the, alleles that make up a gene separate from on another during the formation of gametes. The results proved that some of the data followed Mendel’s law and Chi-Square, test results while other, the null hypothesis was rejected. Lab Sheet: corn+genetics+lab+activity Summary: Our Hypothesis: The genotypes of the parents of this corn are: PpSs x PpSs. (P = purple color, p = yellow color; S = Smooth texture, s = shrunken texture) The purpose of our lab was to examine the traits exhibited on the kernels of corn found on five different rows and discern the genotypes of the parents of the ear of corn. Lab reports are an essential part of the scientific process and are … Continue reading "Proper Lab Report Format You Need to Know to Pass with Flying Colors", Web Publishing Information The HTML comments in this page contain the configurationinformation that allows users to edit pages in your web using the Microsoft Web Publishing Wizard or programs which use the Microsoft Web Publishing Wizard such as FrontPad using the same username and password they would use if they were authoring with Microsoft FrontPage.
