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.
Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
