Part 1: Genes, Chromosomes, and Heredity Chromosome Mapping in Eukaryotes Review
  1. Genes independently if they are on different chromosomes but show if they are on the same chromosome.
     
     
     
     
  2. Genes on the same chromosome would produce gametes if between nonsister chromatids occurs during meiosis.
     
     
     
     
  3. Genes located to each other on the same chromosome are less likely to have cross-over events occur between them.
     
     
     
     
  4. The frequencies between linked genes provide an estimate of the between them (interlocus distance) and can be used to construct a chromosome .
     
     
     
     
  5. The percentage of involved in an exchange between two genes is the percentage of recombinant gametes produced.
     
     
     
     
  6. A crossover (SCO) alters linkage between two genes only if the crossover occurs those two genes.
     
     
     
     
  7. crossovers (DCOs) can be used to determine the order of genes on the chromosome.
     
     
     
     
  8. The mapping technique can be used to map three genes in one cross by two methods.
     
     
     
     
  9. As the distance between linked genes increases, the mapping accuracy due to undetected multiple crossovers that can be predicted by a distribution.
     
     
     
     
  10. The large numbers of mutants in has allowed extensive chromosome mapping in this and other organisms such as maize and mice.
     
     
     
     
  11. Mapping in maize using markers established that crossing over involves a exchange of chromosome regions.
     
     
     
     
  12. In Drosophila, homologs can pair up during , allowing mitotic recombination to take place.
     
     
     
     
  13. Agents that induce chromosome increase the frequency of sister exchange (SCE) during but do not produce recombination.
     
     
     
     
  14. In Neurospora, meiosis produces eight ordered haploid within an , allowing ordered analysis.
     
     
     
     
  15. Somatic cell can be used for testing in which a specific gene product can be correlated with a chromosome.
