Crossing Over in Chicken Oogenesis: Cytological and Chiasma-Based Genetic Maps of the Chicken Lampbrush Chromosome 1 [PDF]

open access: yesJournal of Heredity, 2002
Chiasmata in diplotene bivalents are located at the points of physical exchange (crossing-over) between homologous chromosomes. We have studied chiasma distribution within chicken lampbrush chromosome 1 to estimate the crossing-over frequency between chromosome landmarks.

The Use of Mitotic Crossing-over for Genetic Analysis in Dictyostelium discoideum: Mapping of Linkage Group II [PDF]

open access: yesJournal of General Microbiology, 1975
SUMMARY: Mitotic mapping in the cellular slime mould Dictyostelium discoideum was investigated by analysing the gene order and map distances of four genetic markers on linkage group II: whi, acrA, tsgD (previously reported) and a new spore shape marker sprB.

Genetic variation in recombination in Drosophila. III. Regional effects on crossing over and effects on non-disjunction [PDF]

open access: yesHeredity, 1985
Multiply marked X, 2nd and 3rd chromosomes were used to study the patterns of regional specificity of effects on crossing over of chromosomes from a stock of D. melanogaster selected for high Gl-Sb recombination. It was found that the HX chromosome increased crossover frequencies more or less uniformly throughout chromosome 3, and did not significantly

Induced mitotic crossing-over in relation to genetic replication in synchronously dividing cells ofUstilago maydis

open access: yesGenetical Research, 1965
A method is now available for synchronizing the division of populations of cells of the smut fungusUstilago maydis. In two experiments carried out with a diploid strain heterozygous for several biochemical markers, samples of cells were removed at intervals through the synchronized division cycle and treated with a constant dose of ultra-violet light ...

Genetic Renal Diseases: The Emerging Role of Zebrafish Models

open access: yesCells, 2018
The structural and functional similarity of the larval zebrafish pronephros to the human nephron, together with the recent development of easier and more precise techniques to manipulate the zebrafish genome have motivated many researchers to model human

Selection strategies for the development of maize introgression populations. [PDF]

open access: yesPLoS ONE, 2014
Introgression libraries are valuable resources for QTL detection and breeding, but their development is costly and time-consuming. Selection strategies for the development of introgression populations with a limited number of individuals and high ...
