Games in Tetrads: Segregation, Recombination, and Meiotic Drive [PDF]
, 2012 The two alleles at a heterozygous locus segregate during meiosis, sometimes at meiosis I and sometimes at meiosis II. The timing of segregation is determined by the pattern of crossing‐over between a locus and its attached centromeres.

New Phytologist, Volume 248, Issue 5, Page 2616-2635, December 2025.Summary Hybrid zones provide excellent opportunities to study evolutionary processes linked to interspecific gene flow, including introgression, genetic erosion, polyploid establishment, and speciation. The genus Cardamine (Brassicaceae) serves as an excellent model for polyploid evolution, including one of the few well‐documented neo‐allopolyploid ...

ON THE NATURE OF SPOROGENESIS IN SOME AEROBIC BACTERIA [PDF]
Journal of General Physiology, 1952 Washed vegetative cells of various species of aerobic spore-forming bacteria sporulate abundantly when shaken in distilled water in air. The spores thus formed possess the same heat resistance as spores formed in a complete growth medium. Various factors influencing sporogenesis in water are described. Glucose in low concentration completely suppresses

Food and Energy Security, Volume 14, Issue 5, September/October 2025.ABSTRACT Asian soybean rust (ASR), caused by Phakopsora pachyrhizi, is the most destructive foliar disease of soybean, with yield losses up to 90%. With climate change intensifying drought and expanding disease incidence, it is critical to understand how combined abiotic and biotic stresses influence plant defense.
