Interference in Genetic Crossing over and Chromosome Mapping.
This paper proposes a general model for interference in genetic crossing over. The model assumes serial occurrence of chiasmata, visualized as a renewal process along the paired (or pairing) chromosomes. This process is described as an underlying Poisson process in which the 1st, n + 1th, 2n + 1th, etc., events are to be interpreted as realized chiasmata. Chromatid interference is described in ...
متن کاملChromosome Structure and Crossing Over.
A major obstacle to understanding classical genetic crossing over in higher organisms has been the lack of sufficient knowledge concerning the structure of chromosomes. Without accurate information, in particular, as to how the hereditary substance (DNA) is built into the chromosome, it may be premature to devise models depicting how that material may be recombined in crossing over. In recent y...
متن کاملMeiotic Crossing-over: Obligation and Interference
During meiosis, crossing-over--the exchange of genetic material between maternal and paternal chromosomes--is stringently controlled to restrict the number of crossovers per chromosome pair. In this issue of Cell, Martini et al., (2006) report that the reduction of crossover-initiating events does not result in fewer crossovers. These results have important implications for our understanding of...
متن کاملCrossing-over and interference in a multiply marked chromosome arm of Neurospora.
HE experiments reported here employ Neurospora tetrads for a type of invesT i g a t ion earlier carried out with multiply marked attached-X half-tetrads of Drosophila by EMERSON and BEADLE (1933), BEADLE and EMERSON (1935), BONNIER and NORDENSKIOLD (1937) and WELSHONS (1955), within the theoretical framework developed by such workers as E. G. ANDERSON, C. B. BRIDGES, and A. WEINSTEIN (see WEINS...
متن کاملTemperature Effect on Interference and Crossing over.
A consideration of the data presented in an earlier paper (GRAUBARD 1932) brings out certain facts with regard to the mechanism of crossing over in chromosome I1 of Drosophila melanogaster which may have general significance. In the previous work experiments were performed to study crossing over and interference along the entire length of the normal chromosome I1 and of the same chromosome with...
