Cytological Analysis of Crossover Frequency and Distribution in Male Meiosis of Cardueline Finches (Fringillidae, Aves)

Animals, 2023
Meiotic recombination is an important source of genetic diversity. Using immunolocalization of several meiotic proteins at the spreads of male pachytene cells, we estimated the number of recombination nodules per cell and their distribution along the ...

Effect of Female Age on Crossing Over Frequency in Drosophila melanogaster Crosses N x bcl and N x ym and Their Reciprocals

Biology, Medicine & Natural Product Chemistry, 2023
Crossing over is the occurrence of disconnection and reconnection followed by a reciprocal exchange between the two chromatids in a bivalent form. The crossing event will produce parental type and recombinant type.

Preferential Disomic Segregation and C. micrantha/C. medica Interspecific Recombination in Tetraploid ‘Giant Key’ Lime; Outlook for Triploid Lime Breeding

Frontiers in Plant Science, 2020
The triploid ‘Tahiti’ lime (C. x latifolia (Yu. Tanaka) Tanaka) naturally originated from a merger between a haploid ovule of lemon (C. x limon (L.) Burm) and a diploid pollen from a ‘Mexican’ lime (C. x aurantiifolia (Christm.) Swing).

The unsung hero of science: Barbara McClintock, who won the Nobel Prize in Physiology or Medicine in 1983 for her discovery of mobile genetic elements [PDF]

The Ukrainian Biochemical Journal
In 1983, American plant biologist and cytogeneticist McClintock, one of the great loners of modern­ scien­ce, received the first woman scientist’s unshared Nobel Prize in Physiology or Medicine. Barbara McClintock’s research, conducted in the 1930s, long

Levels of Heterochiasmy During Arabidopsis Development as Reported by Fluorescent Tagged Lines

G3: Genes, Genomes, Genetics, 2020
Crossing over, the exchange of DNA between the chromosomes during meiosis, contributes significantly to genetic variation. The rate of crossovers (CO) varies depending upon the taxon, population, age, external conditions, and also, sometimes, between the

Self-dual quiver moduli and orientifold Donaldson-Thomas invariants [PDF]

, 2015
Motivated by the counting of BPS states in string theory with orientifolds, we study moduli spaces of self-dual representations of a quiver with contravariant involution.

A Complete Set of Solutions For Caustic-Crossing Binary Microlensing Events [PDF]

, 1999
We present a method to analyze binary-lens microlensing light curves with one well-sampled fold caustic crossing. In general, the surface of chi^2 shows extremely complicated behavior over the 9-parameter space that characterizes binary lenses.

Third Chromosome Balancer Inversions Disrupt Protein-Coding Genes and Influence Distal Recombination Events in Drosophila melanogaster

G3: Genes, Genomes, Genetics, 2016
Balancer chromosomes are multiply inverted chromosomes that suppress meiotic crossing over and prevent the recovery of crossover products. Balancers are commonly used in Drosophila melanogaster to maintain deleterious alleles and in stock construction ...
