Quantitative trait loci affecting differences in floral morphology between two species of monkeyflower (Mimulus).

abstract：:Crossovers (COs) between homologous chromosomes are critical for meiotic chromosome segregation and form in the context of the synaptonemal complex (SC), a meiosis-specific structure that assembles between aligned homologs. During Caenorhabditis elegans meiosis, central region components of the SC (SYP proteins) are e...
