New detection of haploid chromosomes, pollen size and sterility in Lychnis indica Benth. var. fimbriata Wall.
Bibliographic record
Abstract
Lychnis indica Benth. a member of the family Caryophyllaceae is commonly distributed in the temperate regions of the Himalayas. Two varieties- var. indica and var. fimbriata are recognized by Hooker in Indian taxa. Presently two accessions of var. fimbriata have been studied meiotically from Dalhousie Hills, Himachal Pradesh, India. Both the accessions uniformly exist at tetraploid level based on x=12 which is confirmed from the presence of 24 bivalents at metaphase I. The present chromosome count of n=24 is the first ever record for var. fimbriata. However, the same tetraploid chromosome number has been reported in the species from Kashmir Himalayas. In majority of the PMCs (pollen mother cells), the meiotic course is regular resulting into normal tetrad formation. However, some PMCs depict the phenomenon of cytomixis involving inter PMC transfer of chromatin material and associated meiotic anomalies. Chromatin transfer resulted into the formation of hypo- and hyper-ploid PMCs. Such PMCs results into the formation of pollen grains of heterogeneous sizes and some pollen sterility.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
