• phenotype
  • 2. Outline the nature and effects on the phenotype of numerical and structural changes of chromosomes. (aber.ac.uk)
  • Discerning the central role of chromosomes in governing the phenotype is an important skill in terms of pursuing a career in clinical and biomedical science. (aber.ac.uk)
  • The gene then needs to be mapped by comparing the inheritance of the phenotype with other known genetic markers. (wikipedia.org)
  • A consensus definition of the concept of epigenetic trait as "stably heritable phenotype resulting from changes in a chromosome without alterations in the DNA sequence" was formulated at a Cold Spring Harbor meeting in 2008, although alternate definitions that include non-heritable traits are still being used. (wikipedia.org)
  • centromere
  • Before this happens, every chromosome is copied once (S phase), and the copy is joined to the original by a centromere, resulting either in an X-shaped structure (pictured to the right) if the centromere is located in the middle of the chromosome or a two-arm structure if the centromere is located near one of the ends.

  • chromatin
  • Some use the term chromosome in a wider sense, to refer to the individualized portions of chromatin in cells, either visible or not under light microscopy. (wikipedia.org)
  • The author has been particularly disappointed by the illogicality of the present chromosomal (chromatin-chromosome) terminology based on, or inferred by, two terms, Chromatin (Flemming 1880) and Chromosom (Waldeyer 1888), both inappropriately ascribed to a basically non coloured state.

  • anaphase
  • In animal cells, chromosomes reach their highest compaction level in anaphase during segregation. (wikipedia.org)

  • Boveri
  • Aided by the rediscovery at the start of the 1900s of Gregor Mendel's earlier work, Boveri was able to point out the connection between the rules of inheritance and the behaviour of the chromosomes. (wikipedia.org)
  • Plants
  • The least number of chromosomes are found in Ascaris megalocephala i.e., 2 (\[n=2\]in Mucor hiemalis in plants ) while in a radiolarian protist ( Aulocantha ) has maximum number of chromosomes is 1600 ( Ophioglossum reticulatum , 2 n = 1262 in plants). (studyadda.com)
  • pattern
  • First generation offspring are heterozygous, requiring them to be inbred to create the homozygous pattern necessary for stable inheritance. (wikipedia.org)
