When a chromosome has either a duplication or a deletion, the chance that the mutation will be harmful are a function of:
A. its location, if it occurs in a germ-line cell, it will be more harmful than if it occurs in a somatic cell.
B. its size, the larger the duplication or deletion, the greater the chance of harm.
C. its position on the chromosome, if it occurs at the tip of a long arm, it is likely to be less harmful than if it occurs at the tip of a short arm.
D. None of the other answer options is correct.
E. its size, the smaller the duplication or deletion, the greater the chance of harm.
Chromosomes that undergo duplication have segments of their DNA repeated while deletion happens when chromosomes have a portion of their sequence removed from he sequence. These are believed to happen side by side when there is unequal crossover of chromosomes during cell division.
