cultural_requirements: A class of genes affecting meiotic recombination in specific loci or regions (175, 520). Initially detected by changed intralocus recombination (up to 25x), but interlocus crossing over may also be affected (up to 40X). Polarity of intralocus recombination may be changed or reduced by the presence of rec+. Any given target locus or region appears to be affected by alleles at only one specific rec locus (Fig. 22). High recombination is recessive. Products of dominant alleles (called rec+) are thought to repress initiation of recombination at specific recognition (cog) sites by binding to an adjacent con(control) site. Control of recombination is independent from control of gene expression (153). Allelic differences are present in commonly used laboratory wild types (174). For reviews, see references 167, 169, 170, and 343.
