_____ have the same chromosome morphology, gene loci, and alleles. Recombination occurs between _____ of homologous chromosomes. Meiosis provides for new combinations of _____ Within a tetrad, each of the two homologous chromosomes has _____ sister chromatids. A fruit fly gamete contains four chromosomes. This means that fruit flies have a diploid chromosome number of _____, and in Metaphase I of Meiosis, _____ chromosome pairs align on the metaphase plate. Mendelian Genetics Read each question carefully and be sure you understand the meaning and application of each term. You may find it helpful to draw diagrams or Punnett squares, or write out genotypes. Mendel’s postulates apply in all cases, and all genomes have a normal number of diploid chromosomes. Each question is worth one point. Considering only one locus on one chromosome pair, what is the maximum number of genetically different gametes? At the locus for flower color, violet is dominant to white. A cross is made between a violet-flowered plant and a white-flowered plant. Among the progeny plants, 27 have violet flowers and 23 have white flowers. What does this information suggest about the genotypes of the parental plants? How many different progeny phenotypes would typically be produced by selfing an individual with genotype AaBb? What is the expected ratio of these phenotypes? How many gamete types would typically be produced by an individual with genotype AaBbCc?
