B. A woman is a carrier of a Robertsonian translocation between chromosomes 18 and 21. (i) Her chromosome set with respect to chromosomes 18 and 21 would consist of which specific chromosomes. Please draw a DIAGRAM illustrating these chromosomes as they would appear in their unreplicated state, clearly labeling the chromosomes and the chromosome arms present. (ii) If this woman were to have a child with a man who possess a completely normal set of chromosomes, there are six different possible outcomes with respect to the combinations of chromosomes 18, 21, and Robertsonian translocation chromosome that could be present in their offspring. Please indicate the TYPES and NUMBERS of chromosomes of each type present in their potential offspring. You may label the chromosomes as follows: 18 (for chromosome 18), 21 (for chromosome 21) or 18/21 (for the Robertsonian translocation chromosome). Also, please indicate the specific genetic abnormality (if any) that would be present in each type of offspring.
