Genetic Algorithms, Orthogonal Arrays and Diploid Chromosomes
… from the orthogonal array contributions a novel diploid chromosomes genetic algorithm that searches for robust optima was developed. Tests showed that it found the required optimum 100% of the time. A set of new measurement techniques suitable for presenting the results of the experiments …

Inference of 3D structure of diploid chromosomes
… fact that most eukaryotes including humans are diploid and therefore contain two (from the available data) indistinguishable copies of each genomic locus. Due to this, the standard approach performs very poorly on diploid organisms. We prove that the 3D organization of the DNA is not …

Studies of androgenic processes in diploid potato
Androgenic processes in diploid potato (2n=2x=24) were studied in three interspecific hybrids. Five incubation temperature treatments were examined. Temperature shock (35°C) during the first 12 h of anther culture and elevated incubation temperature (30°C 16h/20°C 8h) (hereafter 35°C-30°C/20°C) …

Corydoras aeneus: a diploid-tetraploid fish species complex
… with a highly reduced chromosome number. A diploid form of C. aeneus was discovered. Only those fishes from our Belem sample were diploid. A comparison of the diploid and tetraploid forms was done. Both forms were karyotyped, the tetraploid form of C. aeneus has 134 chromosomes and the …

Evaluation of Diploid and Triploid Rainbow Trout in South Dakota Ponds
… triploids tend to be smaller, then surpass diploids after sexual maturation. The purpose of this study was to evaluate the lengths, weights, relative weights (Wr), survival, and gonadosomatic indices (GSI) of triploid and diploid rainbow trout Oncorhynchus mykiss in natural systems. In May …

The relationship between fruit color traits and anthocyanin genes in diploid Fragaria
… locus (yellow fruit color) in Fragaria vesca, a diploid (2n = 2x = 14) strawberry. Using PCR with degenerate primer pairs, intron-containing segments of structural genes coding for the enzymes: chalcone synthase (CHS), chalcone isomerase (CHI), flavanone 3-hydroxylase (F3H), dihydroflavonol …

Incomplete concerted evolution in the non-hybrid diploid Clematic fremontii S. Watston (Rananculaceae)
Clematis fremontii S. Wats. (Ranunculaceae) is a diploid perennial forb with strict habitat requirements that occurs in isolated populations in the cedar glades of Missouri and the mixed-grass prairies of Kansas and Nebraska. Based on geographical isolation and morphological differences, this …

OVERT AND LATENT PATHWAYS OF POLARITY SPECIFICATION IN ZYGOTES: THE HAPLOID-TO-DIPLOID TRANSITION
… cell cycle. The transition from haploid to diploid states involves complex signal transduction cascades, leadingto cell cycle arrest, chemotropic polarized growth, cell-cell fusion and nuclear fusion, culminating in zygote formation. Following substantial remodeling of the cell wall, plasma …

Morphological and Biochemical Analysis of Variation in Diploid Glycine Tomentella Hayata (2N = 38, 40)
… by gaining a greater understanding of the diploid members of the species. A better understanding of the diploids would then be a basis for understanding the complex of tetraploids and for clarifying relationships to other species. A total of 76 diploid accessions plus three outgroup species …

Regulatory Factors of Cellular Senescence in Human Diploid Fibroblast : SA-p-Erk1/2, PP1/2A, PKCα
Proliferation of normal diploid cells is arrested irreversibly after a certain number of divisions, called replicative senescence, which is paragon of the general process of cellular senescence. Once senescent, cells continue to function metabolically, but will not respond to mitogens. Decreased …
