Comparison of Allosyndesis and Autosyndesis at MI between Haploid Darmor-bzh and Yudal

Average Meiotic Behaviora
Autosyndesis

No. of PMCs Ia IC IIAA IICC IIAC III+IV (IIAA+ IICC)/IItot IIAC/IItot
Darmor-bzhb 37 3 (96) 2.2 (66) 0.8 (31) 0.7 (25) 5.2 (203) 0.14 (50) 0.22 0.78

IA and IC indicate univalents belonging to the A and C genomes, respectively; IIAA and IICC indicate autosyndetic bivalents formed between a pair of A or a pair C chromosomes, respectively; IIAC indicates allosyndetic bivalents formed between A and C chromosomes; IIAA + IICC + IIAC = IItot; III and IV indicate trivalents and quadrivalents, respectively.

a

Total number of chromosomes present as IA, IC, IIAA, IICC, IIAC, III, and IV, respectively, are indicated in parentheses.
