Macro‐Hybrid and Micro‐Hybrid of Fish

Reviews in Aquaculture, Volume 18, Issue 1, January 2026.
ABSTRACT This study reviews the progress in fish breeding, focusing on distant hybridization and gynogenesis, and introduces the theory of macro‐hybrid and micro‐hybrid. The macro‐hybrid refers to the allo‐progeny derived from distant hybridization, including the allo‐progenies.

Thermal risk of seed germination of UK's plant populations and implications for climate‐smart ecological restoration

Restoration Ecology, Volume 34, Issue 1, January 2026.
Abstract Introduction Seed‐based ecological restoration actions are needed to halt biodiversity loss and mitigate climate change effects. However, identifying populations to target for climate‐ready seed sourcing remains a major challenge due to germination and genetic constraints.

Cytology, Ploidy and Ploidy Manipulation

2016
The genus Actinidia is remarkable for the variation in ploidy both within and between taxa. There is a structured reticulate pattern of diploids, tetraploids, hexaploids, octoploids and decaploids in diminishing frequency within the genus. The basic chromosome number x = 29 suggests that diploids of Actinidia are in fact palaeopolyploids.

Cytokinesis, ploidy and aneuploidy

The Journal of Pathology, 2011
AbstractCytokinesis is the last step of cell division that physically separates the daughter cells. As such, it ensures the proper inheritance of both nuclear and cytoplasmic contents. Accomplishment of cytokinesis in eukaryotes is dictated by several key events: establishment of the division plane, furrow ingression through contraction of an ...

DNA ploidy in thin melanoma

Pathology, 1988
DNA ploidy in benign nevi (BN), thin non-metastasizing melanomas (TNM) and thin metastasizing melanomas (TMM) was investigated using an image analyser to determine whether characteristics such as nuclear area (NA) and nuclear integrated optical density (IOD) could be used to distinguish between these lesions.

The determination of megakaryocyte ploidy

The International Journal of Cell Cloning, 1990
Methods which have been used to determine megakaryocyte ploidy in animals and humans are reviewed. Although the number of megakaryocyte nuclear units counted in bone marrow squashes is roughly proportional to ploidy, accurate determinations of DNA content require the use of microphotometry or flow cytometry.
