the present study reports the chromosome number and meiotic behaviour of 14 populationsbelonging to four taxa of anchusa subgenus buglossum gusul. from iran. all populationsshowed the chromosome number 2n= 4x= 32. it is the first meiotic study for a. subg.buglossum. we discuss some habit form and evolutionary aspect in the light of cytogeneticdata. the origin of polyploidy (auto-allopolyploidy)...
Intuitively, in four-dimensional gauge theories one counts instantons, and in twodimensional string theory one counts holomorphic curves. These correspond to the instanton counting and curve counting in the title. There is no obvious connection between them, but a remarkable physical idea called geometric engineering [9, 10, 11] dictates that they are indeed related. More precisely, the generat...
Background and Objective: Hybrid cells are made from fusion of two or more somatic cells. After formation chromosomes are located in one membrane . . So nucleic condition of each fused cell has changes and two genomes and chromosomes interact with each other. Locating the genes in new nucleic and cytoplasmic condition and great chromosomal rearrangement in these new formed cells can affect th...
Abstract Selection not only increases the frequency of new-useful mutations but also remains some signals throughout the genome. Since these areas are often control economically important traits, identifying and tracking these areas is the most important issue in the animal genetics. The aim of this study was to detecting signals of selection in the genome of Turkmen horse using 70K SNP chip...
