A test of a counting model for chiasma interference.
According to the model of FOSS, LANDE, STAHL and STEINBERG, chiasma interference is a reflection of the requirement for crossovers to be separated by an organism-specific number of potential conversion events without associated crossovers. This model predicts that tetrads with close double crossovers should be enriched for conversion events that themselves are not associated with crossing over....
متن کاملA polymerization model of chiasma interference and corresponding computer simulation.
A model of chiasma interference is proposed and simulated on a computer. The model uses random events and a polymerization reaction to regulate meiotic recombination between and along chromosomes. A computer simulation of the model generates distributions of crossovers per chromosome arm, position of events along the chromosome arm, distance between crossovers in two-event tetrads, and coincide...
متن کاملBlind Fractional Interference Alignment
Fractional Interference Alignment (FIA) is a transmission scheme which achieves any value between [0,1] for the Symbols transmitted per Antenna per Channel use (SpAC). FIA was designed in [1] specifically for Finite Alphabet (FA) signals, under the constraint that the Minimum Distance (MD) detector is used at all the receivers. Similar to classical interference alignment, the FIA precoder also ...
متن کاملAn Analysis of Chiasma Pairs Showing Chromatid Interference in Trillium Erectum L.
NTIL comparatively recently there has been no compelling evidence U that genetic “interference” involves more than the occurrence of one crossover reducing the chance of another occurring in nearby regions. Genetic data from Drosophila have generally been interpreted as indicating that there is no “chromatid interference,” that is, that a crossover between two of the four chromatids does not in...
متن کاملCentromeres
Also known as... The terms ‘centromere’ and ‘kinetochore’ are often used synonymously but it is best to consider the centromere as the DNA and chromatin on which the kinetochore is assembled and the kinetochore as the protein machine, including centromeric chromatin, which mediates attachment to the spindle. Centromeres are found near the centre of the chromosome on metacentric chromosomes, but...
