Which chromosomal defect is caused when part of a chromosome breaks off at either end and attaches to another chromosome?

Answer
A
insertion
B
translocation
C
deletion
D
nondisjunction

Explanation

When a chromosome segment breaks off and attaches to a different chromosome, the defect is called a translocation. A deletion is loss of a segment, while nondisjunction is the failure of chromosomes to separate properly. Insertion means a segment is added within a chromosome, not moved to another chromosome.
