Summary
Twenty-two sexual crosses between strains of Phycomyces blakesleeanus carrying mutations affecting phototropism (madA, madD, madE), synthesis of carotenoids (carA), auxotrophy (leu-51, nicA, pur-51), and resistance to 5-fluorouracil (fur) were studied; mating type was also included as a marker. Recombination frequencies were obtained among the ten genes involved. Linkage was found between mating type and madE; leu-51 and madA; furA401, furB402 and madD. All other gene combinations tested are unliked.
