The fertility and crossing behavior of a tetraploid hybrid of 4x Andean blueberry (V. meridionale) and lingonberry (V. vitis-idaea) was evaluated through a series of crosses. Crosses of the hybrid with highbush blueberry produced divergent results.

Distant hybridization is a significant method for creating new hybrid lineages and potentially hybrid species. In the past ten years, we have established a hybrid lineage population, BTF1-BTF6 (six generations), via crosses between Megalobrama ...

Ploidy Status of Ovarian Cancer Cell Lines and Their Association with Gene Expression Profiles
As a cancer type potentially dominated by copy number variations, ovarian cancer shows hyperploid karyotypes and large-scale chromosome alterations, which might be promising biomarkers correlated with tumor metastasis and chemoresistance.

Application of Flow Cytometry to Determine Cell DNA Content in the Genetic Breeding of Fish
In the field of fish genetic breeding, accurately determining the DNA content and ploidy of fish is of great significance. This article introduces the use of flow cytometry (FCM) to measure the DNA content and conduct ploidy analysis by sampling ...

Full-Length Transcriptome Reveals Heterologous Sperm Fragments in Natural Gynogenetic Grass Carp
Grass carp (Ctenopharyngodon idella) is one of the most economically important cyprinid species cultured in China. The diploid gynogenetic grass carp (2nGGC, 2n = 48) was generated from the hybrid of female grass carp (GC, 2n = 48) and male topmouth ...

Polyploidization and epigenetics [PDF]
The occurrence of polyploidy, or whole genome duplication, can result in instantaneous speciation. Because new polyploids are immediately reproductively isolated from their non-polyploid congeners, polyploidization has played an important role in the diversification of flowering plants and some vertebrates.
