  • differences
  • The conservation of this division between macro- and microchromosomes over a long evolutionary timescale makes it interesting to characterize the similarities and differences between the two types of chromosomes, including the distribution of epigenetic marks. (biomedcentral.com)
  • Attention is paid to their length, the position of the centromeres, banding pattern, any differences between the sex chromosomes, and any other physical characteristics. (wikipedia.org)
  • mechanisms
  • Genomic studies in non-domestic avian models, such as the California condor and white-throated sparrow, can lead to more comprehensive conservation plans and provide clues for understanding mechanisms affecting genetic variation, adaptation and evolution. (biomedcentral.com)
  • found
  • Then, in 1959 Susumu Ohno proved that these satellite-like structures found exclusively in female cells were actually derived from female X chromosomes. (wikipedia.org)
  • female
  • On November 3, 2010, scientists announced the discovery of a female Boa constrictor that can produce offspring without mating and, through such asexual reproduction, produced 22 female offspring, all with a WW chromosome genetic makeup. (wikipedia.org)
  • However, because of their WW chromosomes, any offspring they produce will be female. (wikipedia.org)
  • Long-suspected connection between female sex hormones and development of cancer identified for the first time. (cshlpress.com)
  • common
  • To determine whether this is likely to be a common feature of amniote microchromosomes, we have analysed the distribution of epigenetic marks using immunofluorescence on metaphase chromosomes of the central bearded dragon ( Pogona vitticeps ). (biomedcentral.com)
  • multiple
  • Our karyotypic analyses of the sparrow in combination with other studies indicate that the rearrangements in both chromosomes 2 m and 3 a are complex and likely involve multiple inversions, interchromosomal linkage, and pleiotropy. (biomedcentral.com)

  • Simultaneously, Mary F. Lyon began investigating manipulations of X-linked traits that had phenotypically visible consequences, particularly in mice, whose fur color is a trait intimately linked to the X chromosome. (wikipedia.org)

  • Simultaneously, Mary F. Lyon began investigating manipulations of X-linked traits that had phenotypically visible consequences, particularly in mice, whose fur color is a trait intimately linked to the X chromosome. (wikipedia.org)

  • Mutations can also be observed directly every so often right after meiotic divisions of the sex cells. (blogspot.com)
