In this study, we report a woman who carries a unique pericentric inversion of one chromosome 21: inv (21) (p12; q22).
Two Down syndrome patients with rec(21),dupq,inv(21)(p11;q2109) from a familial pericentric inversion.
Pericentric inversion of chromosome 9: prevalence in 300 Down syndrome families and molecular studies of nondisjunction.
Two pericentric inversions, inv(2) (p11q13) and inv(5)(p13q13), in a patient referred for psychiatric problems.
Trimerotropis pallidipennis is an American grasshopper whose South American populations are polymorphic for pericentric inversions
(Mesa 1971, Vaio et al.
Lack of underdominance in a naturally occurring pericentric inversion in Drosophila melanogaster and its implications for chromosome evolution.
Pericentric inversion heteromorphism of the F5 cytotype.
1995), but this study provides no direct evidence for underdominance in the Tulancingo hybrid zone associated with the centric fissions of chromosomes 1, 3, 4, and 6 or the pericentric inversion of chromosome 4.
Fine structure and behaviour of a pericentric inversion in the sand rat, Psammomys obesus.
The relative length of chromosomes 1 to 18 was not different between the species, but 5 of their chromosomes (numbers 4, 7, 9, 11, & 18) were significantly different in relative lengths of short and long arm and in centromeric index, differences that can be explained by pericentric inversions
The sex chromosomes consist of three variations of subtelocentric, telocentric, and metacentric types caused by two pericentric inversions
and conduct the different sex determining systems (19,20).
severum (Heckel, 1840), which show a smaller number, mainly through robertsonian rearrangements and pericentric inversions
Examples of pericentric inversions
, partial-arm translocations, or multiple translocation/inversion events were observed less frequently.
