In maize, the bp, wx genes are located on chromosome IX. These genes are recessive in relation to the norm and determine the development of the following signs of the caryopsis: bp – brown color of the pericarp, wx – waxy endosperm. In Fa, 600 plants were obtained, of which 281 had dominant characters; 298 – recessive; 9 – caryopses with brown pericarp and normal endosperm; 12 – caryopses with normal pericarp and waxy endosperm. Determine the distance between the bp and wx genes in morganids.

The distance between the bp and wx genes is 3.5 morganids.
