Answer is : E) A and B are correct Gene dosage is defined as number of times a given gene is present in the nucleus of cell. Imbalance in gene dosage alter the amount of a particular protein relative to all other proteins, and lead to variety of phenotypic effects. Deletion causes loss of part of a chromosome that results on monosomy for that segment of the chromosome. Duplication results in doubling of part of a chromosome, resulting in trisomy for that segment. Thus, gene dosage result is either decrease or increase in that part of a chromosome...
