  • They found that during evolution, a reshuffling of DNA known as translocation brought together separate chunks of sex-determining genes onto a single chromosome, essentially mimicking the human X or Y chromosome. (duke.edu)
  • In the 1960's, Japanese-American geneticist and evolutionary biologist Susumu Ohno proposed a theory in which the genes determining sex first arose at various spots scattered across the entire genome, but over time were "captured" on the sex chromosomes. (duke.edu)
  • In C. amylolentus, dozens of genes at two different locations on the chromosomes control what's called a tetrapolar, or four-part, mating system. (duke.edu)
  • The researchers sequenced the entire genome of C. amylolentus, mapping the location of all the genes as well as the centromeres on each of the organism's 14 chromosomes. (duke.edu)

  • Sequencing of several candidate genes within the mapped interval led to negative findings in terms of the underlying molecular pathogenesis of the disease in the family. (csic.es)
  • The discovery of more mutated genes allowed Morgan's group to explore how genes are arranged on the chromosome, and to discover an exception to one of Mendel's laws of inheritance. (jrank.org)
  • T is a deletion (see Table 1 for all genes mentioned) that includes a semidominant mutation that has been found in only non- t -carrying wild-type chromosomes. (genetics.org)
  • Autosomes still contain sexual determination genes even though they are not sex chromosomes. (wikipedia.org)
  • susceptibility
  • In this largest fine-mapping study to investigate a large number of rare and novel variants within 5p15.33, we identified novel lung and adenocarcinoma susceptibility loci with large effects and provided support for the role of telomere length as the potential underlying mechanism.

  • The human NAT loci (NAT1, NAT2, and a pseudogene, NATP) have been mapped to human chromosome 8p22, a region frequently deleted in tumours. (ox.ac.uk)
  • We also provide sequence information and a restriction map in the vicinity of Nat1 and Nat2 and describe a noncoding exon located 6 kb upstream of the Nat2 coding region. (ox.ac.uk)
  • A region of shared homozygosity on chromosome 10p13-p12.1 was identified in the three affected individuals. (diabetesjournals.org)
