In Datura, the purple color of flowers (P) dominates over white (p), and prickly seed pods (S) over smooth (s).

In Datura, the purple color of flowers (P) dominates over white (p), and prickly seed pods (S) over smooth (s). A purple-flowered plant with smooth bolls, crossed with a white-flowered, thorny boll, yielded 320 purple-flowered with thorns and 312 purple-flowered with smooth bolls. Determine what phenotypes and genotypes the offspring will have, obtained from crossing with each other hybrid F1 plants.

Genotypes of offspring obtained from crossing between hybrid F1 plants – PpSs, Ppss in a 1: 1 ratio; the phenotypes of the offspring are purple-flowered plants with spiny bolls and purple-flowered plants with smooth bolls in a 1: 1 ratio.

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.
