Question

Following are a few statements regarding mapping populations and principles of genetic mapping in crop species. A. For self-pollinating species, both F2 and F1-derived doubled haploids can serve as mapping populations. B. For cross-pollinating species, F1 population can be used for mapping studies. C. Bulk segregant analysis (BSA) is often used to identify linked markers for complex traits with multiple genes and environmental influences. D. In crop plants, sets of different breeding lines can be exploited for trait mapping. E. Breeding methods such as single-seed descent and pedigree selection promote genetic variability. Which one of the following options represents the combination of all INCORRECT statements?
