GIVE AN ACCOUNT OF THE ROLES OF GENETIC MUTATIONS AND MEIOSIS IN GENERATING GENETIC DIVERSITY (20) Marking Scheme Synopsis‚ Clarity‚ English Language‚ sequence of events (3) Introduction (1)‚ Scientific content (15)‚ Conclusion (1). Introduction: Genetic Diversity: Every individual has a unique genotype. This is equal to the combination of alleles of all its genes. The greater the number of genotypes in a population‚ the greater the genetic diversity. Genetic mutations produce new alleles

Determining the Crossover Frequency in Sordaria fimicola Introduction Meiosis is an important part of the life cycle that gives rise to the genetic variation in offsprings. Meiosis in fungi differs from those in plants and animals. Fungi are composed of hyphae‚ which are tubules that make up the frame. These hyphae together form a clump or a mat that is the mycelium (Campbell‚ 637). The hyphae are key to fungus reproduction. Typically fungi produce large amounts of spores through either sexual

is derived from the person’s mother and the other from the person’s father. Meiosis‚ on the other hand‚ occurs only in testis and ovary tissues‚ producing sperm and ova (eggs). The gametes that are produced by meiosis in humans are haploid‚ containing only one copy of each of the twenty-three chromosomes. Because of recombination and independent assortment of parental chromosomes‚ the daughter cells produced by meiosis are not genetically

Biology 260: gENETICS | CROSSES OF SORDARIA | Sordaria of Tan and Grey Allele | | Abstract: To understand the details of genetic behavior‚ Sordaria fimicola is used in this study by observing the asci produced from monohybrid and dihybrid crosses with observance to recombination. This experiment performed extended over a three week period. The strains that were used from S. fimicola were wild type producing black‚ and mutants producing grey and tan strains. There are seven possible phenotypes

AP BIOLOGY- Mitosis and Meiosis Cell Division Lab Part 1-MITOSIS summary: In this experiment first the stages of an onion cell undergoing mitosis are going to be observed and every stage is going to be detected and drawn on paper. A brief description to what is going on should be attached to the pictures. This is important to understand the basics of cell division which is necessary growth‚repair

Meiosis 1. What does it mean when two sets of chromosomes are homologous? It means that each of the four chromosomes that come from the male parent has a corresponding chromosomes from the female parent. 2.

Ryan Juergens 01/29/2013 Pd:05th Mitosis VS. Meiosis All living things are made of cells from bacteria to the most complex being on earth us. These cells must reproduce in some way one method is mitosis that would take place in bacteria while‚ another way is meiosis one that you may have heard of in sex education. These‚ two processes may seem similar at first but as you take a closer look like we do in this essay you will learn that these processes are very different in many distinctive
