Solution
The correct option is B Trisomics
Trisomics are those organisms, which have an extra chromosome (2n + 1). Trisomics were obtained for the first time in Datura stramonium (jimson weed) by A.F. Blakeslee and his co-workers. Since haploid chromosome number in this species is n = 12, 12 primary trisomics, 24 secondary trisomics and a large number of tertiary trisomics are possible. Most of the trisomics were identified by size, shape and other morphological features of the fruit.So, the correct answer is 'Trisomics'.
