Question

Given below are a few statements related to biological principles and/or techniques: A. Genetic diversity plays an important role in the identification of combiners for heterosis breeding B. Genotyping by sequencing (GBS) can be used to identify allelic diversity but is not useful for construction of linkage maps. C. Genome editing by sequence specific nucleases (SSNS) in the presence of guide RNAs would result in NHEJ-mediated knock outs and loss of function mutations. D. In a comparison of synteny and colinearity between diploid and polyploid plant genomes, colinearity is high but synteny is low. Which one of the following options represents all correct statements?
