Genetics of Ustilago violacea. III. Crossing Over and Nondisjunction

Botanical Gazette, 1978
The frequency of crossing over between two sporidial color mutations, between mutant sites in the white (w) locus and the centromere, and between two complementing mutations in the w locus was determined by teliospore colony (intact tetrad) analysis.

Apparent Double Crossing-Over in a Short Genetic Interval in Drosophila melanogaster

Nature, 1960
IN view of the reported occurrence of double crossing-over within a short genetic interval in Aspergillus 1 and of the purported existence of negative interference in bacteriophage2, it is worth while to record the recovery in Drosophila melanogaster of apparent double cross-over types within a short genetic interval where interference is nominally ...

Crossing-over modifiers and other genetical changes in the crossing-over value

1932
This is probably one of the most fascinating chapters in analytic genetics, and one of the most important chapters in cyto-genetics. The fact is, as Rasmusson (93) puts it, “... the linkage values are inherited as any quantitative character of any organism propagating in a sexual way ....

Vigenere and genetic cross-over acting at the restricted ASCII code level for color image encryption

Medical & Biological Engineering & Computing, 2022
In the current high-tech era, the growing popularity of e-healthcare has heightened the attention focused on data security against cyber-attacks. As digital medical images are transported over the public network, an intermediate degree of protection must be in place.

Ring Cross Over Based Genetic Algorithm For DFMB Chip Design And Medical Image Compression

Current Signal Transduction Therapy, 2019
Objective: Recent days, medical data are stored in the cloud for easy access and sharing the data of patients between the health center for treatments. In such a situation, the data stored in the cloud should be of lesser size to accommodate more information.

Unequal crossing over and the genetical organization of the white locus ofDrosophila melanogaster

Zeitschrift f�r Vererbungslehre, 1963
Unequal crossing over occurs in females heterozygousw a /w a4 such that a deficiency and duplication can be recovered regularly. A triplication was also found following crossing over in the homozygous duplication.

Modified cross-over techniques in genetic algorithm for performance enhancement of retinal image classification system

Third International Conference on Computational Intelligence and Information Technology (CIIT 2013), 2013
Abnormality identification in retinal images has become one of the significant applications in the field of medical image analysis. Most of the detection techniques are computer aided which involves several computing techniques. One of the significant computing techniques is optimization which is extremely important for any abnormality detection system.

[Genetic control of mitotic crossing over in yeasts. IV. The induction of mitotic crossing over by chemical mutagens with different mechanisms of action].

Genetika, 1983
The genetic effects of methyl methanesulphonate (MMS) and bifunctional quinacrine mustard (QM) have been studied in three diploid strains of the yeast Saccharomyces cerevisiae: T1, with normal radiosensitivity, T2 - the excision-deficient mutant (rad2 rad2) and T3 - the mutant defective in recombinational repair (rad54 rad54).

Linkage of genetics and ethics: more crossing over is needed.

Biology of the cell, 2005
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
