Prior Mating Experience Modulates the Dispersal of Drosophila in Males More Than in Females [PDF]

open access: yes, 2011
Cues from both an animal’s internal physiological state and its local environment may influence its decision to disperse. However, identifying and quantifying the causative factors underlying the initiation of dispersal is difficult in uncontrolled ...

Genetic Regulation of Meiotic Cross-Overs between Related Genomes inBrassica napusHaploids and Hybrids   [PDF]

open access: yesThe Plant Cell, 2009
AbstractAlthough the genetic regulation of recombination in allopolyploid species plays a pivotal role in evolution and plant breeding, it has received little recent attention, except in wheat (Triticum aestivum). PrBn is the main locus that determines the number of nonhomologous associations during meiosis of microspore cultured Brassica napus ...

INTERFERENCE IN GENETIC CROSSING OVER AND CHROMOSOME MAPPING

open access: yesGenetics, 1979
ABSTRACT 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 Ist, n + 1th, 2n + 1th, etc., events are to be ...

Variation in human recombination rates and its genetic determinants. [PDF]

open access: yesPLoS ONE, 2011
Despite the fundamental role of crossing-over in the pairing and segregation of chromosomes during human meiosis, the rates and placements of events vary markedly among individuals.

The system of genetic exchange in Trypanosoma brucei and other trypanosomatids [PDF]

open access: yes, 2007
In this chapter, we discuss our current understanding of the systems of genetic exchange in trypanosomatids and the im-pact the recent genome projects have had on this area of research.

Point Contacts in Modeling Conducting 2D Planar Structures [PDF]

open access: yes, 2015
Use of an optimization algorithm to improve performance of antennas and electromagnetic structures usually ends up in planar unusual shapes. Using rectangular conducting elements the proposed structures sometimes have connections with only one single ...
