Question
A species of plant (species 1) is diploid (2n = 6) with chromosomes AABBCC and a related species (species 2) is also diploid {2n = 4) with chromosomes PPQQ. The following statements were given by students regarding the chromosome numbers involving these plant species: A. Autotriploid of species 1 will have 12 chromosomes B. Allotetraploid involving species 1 and 2 will have 16 chromosomes C. A monosomy in species 1 will generate 5 chromosomes D. A double trisomy in species 1 will generate 8 chromosomes E. A nullisomy in species 2 will generate 2 chromosomes The combination of statements with all correct answers is:
Explanation
Analysis of a species of plant (species 1) is shows C, D and E represents established outcome. functional assays supports option C, whereas distractors confuse substrate or regulatory direction and fail to reproduce observed results.
