Make correction wherever you mistake in spellings/words in the followong paragraph/sentence. A. A successful breeding for disease susceptability depends mainly on two factors : (i) a good source of resistance, and (ii) a dependable disease test, all the grown under conditions in which a resistant plant is exoected to develop disease. This allows a clear cut identification of the disease resistant plants, which are then discarded. B. Humans have produced a new autopolyloid crop called triticale in the following manner. Autoteraploid wheat (Triticum Sativum) was hybridised with rye (Seeale cereale). The chromosome number of the resulting `F_(1)` was trippled to produce triticale. C. Phenotype is genetic make up of an individual or a variety. In contrast, the genotype is the observable features of an organism. |

Answer» A. A successful breeding for disease resistance depends mainly on two factors : (i) a good source of resistance, and (ii) a dependable disease test. In disease test,all the plants are grown under conditions in which a susceptible plant is expected to develop disease. This allows a clear0cut identification of the disease resistant plants, which are then selected. B. Humans have produced a new allopolyploid crop called Triticale in the following manner. Allotetraploid wheat (Triticum turgidum) was hybridised with rye (Secale cereale). The chromosome number of the resulting `F_(1)` was doubled to produced Triticale. C. Genotype is the genetic make up of an individual or a variety. In contrast, the phenotype is the observable features of organism. |
