Abstract

Spermatogenesis is a finely regulated process of germ cell multiplication and differentiation leading to the production of spermatozoa in the seminiferous tubules. Spermatogenesis can be divided into three parts: spermatocytogenesis, meiosis and spermiogenesis. During spermatocytogenesis, germ...

Abstract

Western honey bees (Apis mellifera) far exceed the commonly observed 1-2 meiotic recombination events per chromosome and exhibit the highest Metazoan recombination rate (20 cM/Mb) described thus far. However, the reasons for this exceptional rate of recombination are not sufficiently understood. In ...

Abstract

Meiotic recombination contributes to augmentation of genetic diversity, exclusion of deleterious alleles and proper segregation of chromatids. PRDM9 has been identified as the gene responsible for specifying the location of recombination hotspots during meiosis and is also the only known vertebrate ...

Abstract

Recombination is a major evolutionary force, increasing genetic diversity and permitting efficient coevolution of fungal pathogen(s) with their host(s). The ascomycete Fusarium graminearum is a devastating pathogen of cereal crops, and can contaminate food and feed with harmful mycotoxins. Previous ...

Abstract

A detailed cytogenetic analysis of the aspidogastrean fluke Aspidogaster limacoides revealed a karyotype consisting of six medium-sized chromosome pairs. The first and the last pairs were two-armed while four remaining were one-armed; 2n=12, n=1 m+1 m-sm+4a. Fluorescence in situ hybridization with...

Abstract

Semen was treated with ultraviolet irradiation to genetically inactivate the sperm. Gynogenetic haploidy was induced artificially in the German mirror carp, Cyprinus carpio L. A systematic study of the status of early embryonic development, the number of chromosomes, chromosomal banding patterns...

Abstract

Despite similar genome sizes, a great variability in recombination rates is observed in mammals. We used antibodies against SYCP3, MLH1 and centromeres to compare crossover frequency, position along chromosome arms and the effect of crossover interference in spermatocytes of 4 species from the...

Abstract

Sturgeons (order Acipenseriformes) are members of an ancient evolutionary lineage that has experienced multiple rounds of whole-genome duplication. As a result, most extant species are polyploid and possess more than two complete sets of chromosomes. While interspecific variation in ploidy and...

Abstract

Interspecific hybridization, polyploidization and transitions from sexuality to asexuality considerably affect organismal genomes. Especially the last mentioned process has been assumed to play a significant role in the initiation of chromosomal rearrangements, causing increased rates of karyotype...

Abstract

Intragenomic conflict has the potential to cause widespread changes in patterns of genetic diversity and genome evolution. In this study, we investigate the consequences of sex-ratio (SR) drive on the population genetic patterns of the X-chromosome in Drosophila neotestacea. An SR X-chromosome...
