Genetic exchange across a paracentric in version of the mouse t complex.
74) The most common rearrangement event, a small paracentric intrachromosomal inversion fusing EML4 and ALK, may be difficult to perceive because it may lead to a subtle split in the probes, leading to false-negative results if overlooked, and to false-positive results as a result of assay noise due to aberrant probe hybridization or high background signal.
Shields and Procunier (1982) described four sibling species of the Simulium arcticum complex in Alaska, and Procunier (1984) described a fifth in western Canada based on possession of unique paracentric inversions in Y chromosomes.
Other rearrangements involving 12q14~q15, such as paracentric inversions, have also been reported.
The presence of translocations, paracentric inversions or fusions and differences in C-banding patterns of their chromosomes by amplification or shrinking of heterochromatic segments, reveal a complex multispaced genome configuration where about 30 different clones of W.
Often, the roof hatches are designed with security locks, requiring the use of a paracentric or mogel key to unlock them.
Crossovers within the loops of both pericentric and paracentric inversions result in chromatids with duplications and deficiencies.
They owe their prevalence in part to two biological peculiarities of Drosophila that minimize the harmful effects of crossing-over within a paracentric inversion loop.
This chromosome has been shown to be polymorphic for up to six paracentric inversions (Ruiz et al.
As with the food service equipment, CDC conducted a field survey of the durability, maintenance and operational characteristics of hollow metal cell doors, glazing, security glazing, electro-mechanical door-sliding mechanisms and both paracentric and mortise locksets.
