Creation of doubled haploid lines of maize Zea mays L. by resynthesis from a tetraploid population
The search for new, effective methods for broadening the genetic polymorphism of the original breeding material remains one of important problems of hybrid maize breeding.

Modeling Heavy-Ion Fusion Cross Section Data via a Novel Artificial Intelligence Approach [PDF]
We perform a comprehensive analysis of complete fusion cross section data with the aim to derive, in a completely data-driven way, a model suitable to predict the integrated cross section of the fusion between light to medium mass nuclei at above barrier energies.

INTERFERENCE IN GENETIC CROSSING OVER AND CHROMOSOME MAPPING
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 ...

Genetic Programming Crossover: Does It Cross over? [PDF]
One justification for the use of crossover operators in Genetic Programming is that the crossover of program syntax gives rise to the crossover of information at the semantic level. In particular, a fitness-increasing crossover is presumed to act by combining fitness-contributing components of both parents.

Several genetic tools have been developed for genome engineering in Clostridium acetobutylicum utilizing 5-fluorouracil (5FU) or 5-fluorocytosine (5FC) resistance as a selection method.

My Favorite Sites: Linkage of genetics and ethics: more crossing over is needed [PDF]
Since the development of recombinant DNA technology in the mid 1970s, there has been increasing interest in the ethical, legal, and social implications of genetics and related fields. The web sites of five different organizations (government, academic, and independent not‐for‐profit) that deal explicitly with genetics and ethics are reviewed here. Some

Background Homology-based recombination (HR) is the cornerstone of genetic mapping. However, a lack of sufficient sequence homology or the presence of a genomic rearrangement prevents HR through crossing, which inhibits genetic mapping in relevant ...

Comparison Study for Clonal Selection Algorithm and Genetic Algorithm [PDF]
Two metaheuristic algorithms namely Artificial Immune Systems (AIS) and Genetic Algorithms are classified as computational systems inspired by theoretical immunology and genetics mechanisms. In this work we examine the comparative performances of two algorithms.

The dual nature of TDC – bridging dendritic and T cells in immunity
TDC are hematopoietic cells combining dendritic and T cell features. They reach secondary lymphoid organs (SLOs) and peripheral organs (liver and lungs) after FLT3‐dependent development in the bone marrow and maturation in the thymus. TDC are activated and enriched in SLOs upon viral infection, suggesting that they might play unique immune roles, since

Meiosis is a process of essential importance for sexual reproduction, as it leads to production of gametes. The recombination event (crossing-over) generates genetic variation by introducing new combination of alleles.
