In genetics , chromosomal polymorphism is a condition where one species contains members with varying chromosome counts or shapes. Polymorphism biology Polymorphism is a general concept in biology where more than one version of a trait is present in a population. In some cases of differing counts, the difference in chromosome counts is the result of a single chromosome undergoing fission, where it splits into two smaller chromosomes, or two undergoing fusion, where two chromosomes join to form one. This condition has been detected in many species. Trichomycterus davisi , for example, is an extreme case where the polymorphism was present within a single Chimera genetics chimeric individual. ref cite journal journal Genet. Mol.

Use dmy dates date February 2012 Y chromosomal Aaron is the name given to the hypothesised most recent common ancestor of many of the patrilineal descent patrilineal Jewish priestly caste known as Kohen Kohanim singular Kohen , Cohen , or Kohane . In the Torah , this ancestor is identified as Aaron , the brother of Moses . The hypothetical most recent common ancestor was therefore jocularly dubbed Y chromosomal Aaron , in analogy to Y chromosomal Adam . Although most priestly functions of the Kohanim such as Temple sacrifices ended with the destruction of the second Temple by the Romans in 70 CE, the identity of Kohanim has been carefully preserved throughout history. In traditional synagogues, a Kohen will always be the first person called to the Torah, will be asked to publicly bless the congregation at specified times, will be asked to bless a bride and groom at the wedding, and will be asked to redeem every first born male child. Until recently, however, there was neither scientific support nor continuous written record to support the claim of patrilineal descent from Aaron. The original scientific research was based on the discovery that a majority of present day Jewish Kohanim either share, or are only one step removed from, a pattern of values for 6 Y STR markers, which researchers named the Cohen Modal Haplotype CMH . However it subsequently became clear that this six marker ... Y chromosomal Haplogroup J1c3 Y DNA haplogroup J1c3 also called J P58 , do indeed appear to be very ... .

Image Inversioncartoon.gif thumb right 250px A clay model showing why heterozygous inversion loops are visible in polytene chromosome preparations Image a arm inversion.jpg thumb right 250px An inversion loop in the A arm of a chromosome from an Axarus species midge An inversion is a chromosome rearrangement in which a segment of a chromosome is reversed end to end. An inversion occurs when a single chromosome undergoes breakage and rearrangement within itself. Inversions are of two types paracentric and pericentric . Paracentric inversions do not include the centromere and both breaks occur in one arm of the chromosome. Pericentric inversions include the centromere and there is a break point in each arm. Cytogenetic techniques may be able to detect inversions, or inversions may be inferred from genetic analysis . Nevertheless, in most species small inversions go undetected. In insects with polytene chromosome s, for example Drosophila , preparations of larval salivary gland chromosomes allow inversions to be seen when they are heterozygous . This useful characteristic of polytene chromosome s was first advertised by Theophilus Shickel Painter in 1933. ref cite journal author Painter TS year 1933 title A new method for the study of chromosome rearrangements and the plotting of chromosome maps journal Science volume 78 pages 585 586 pmid 17801695 doi 10.1126 science.78.2034.585 issue 2034 ref Inversions usually do not cause any abnormalities in carriers as long as the rearrangement is balanced with no extra or missing genetic information. However, in individuals which are heterozygous for an inversion, there is an increased production of abnormal chromatids this occurs when crossing over occurs within the span of the inversion . This leads to lowered fertility due to production of unbalanced gametes. The most common inversion seen in humans is on chromosome 9 , at inv 9 p12q13 . This inversion is generally considered to have no deleterious or harmful effects, but the ... more details
